The term “processor” may refer to an arbitrary logic circuitry configured to perform basic operations of a computer or system, and/or, generally, to a device which is configured for performing calculations or logic operations. In particular, the processor, or computer processor may be configured for processing basic instructions that drive the computer or system. It may be a semi-conductor based processor, a quantum processor, or any other type of processor configures for processing instructions. As an example, the processor may be or may comprise a Central Processing Unit (“CPU”). The processor may be a (“GPU”) graphics processing unit, (“TPU”) tensor processing unit, (“CISC”) Complex Instruction Set Computing microprocessor, Reduced Instruction Set Computing (“RISC”) microprocessor, Very Long Instruction Word (“VLIW”) microprocessor, or a processor implementing other instruction sets or processors implementing a combination of instruction sets. The processing means may also be one or more special-purpose processing devices such as an Application-Specific Integrated Circuit (“ASIC”), a Field Programmable Gate Array (“FPGA”), a Complex Programmable Logic Device (“CPLD”), a Digital Signal Processor (“DSP”), a network processor, or the like. The methods, systems and devices described herein may be implemented as software in a DSP, in a micro-controller, or in any other side-processor or as hardware circuit within an ASIC, CPLD, or FPGA. It is to be understood that the term processor may also refer to one or more processing devices, such as a distributed system of processing devices located across multiple computer systems (e.g., cloud computing), and is not limited to a single device unless otherwise specified.
The memory 104 may refer to a physical system memory, which may be volatile, non-volatile, or a combination thereof. The memory may include non-volatile mass storage such as physical storage media. The memory may be a computer-readable storage media such as RAM, ROM, EEPROM, CD-ROM, or other optical disk storage, magnetic disk storage, or other magnetic storage devices, non-magnetic disk storage such as solid-state disk or any other physical and tangible storage medium which can be used to store desired program code means in the form of computer-executable instructions or data structures and which can be accessed by the computing system. Moreover, the memory may be a computer-readable media that carries computer-executable instructions (also called transmission media). Further, upon reaching various computing system components, program code means in the form of computer-executable instructions or data structures can be transferred automatically from transmission media to storage media (or vice versa). For example, computer-executable instructions or data structures received over a network or data link can be buffered in RAM within a network interface module (e.g., a “NIC”), and then eventually transferred to computing system RAM and/or to less volatile storage media at a computing system. Thus, it should be understood that storage media can be included in computing components that also (or even primarily) utilize transmission media.
The computing nodes 101, 101.1 . . . 101.n may include multiple structures 106 often referred to as an “executable component, executable instructions, computer-executable instructions or instructions”. For instance, memory 104 of the computing nodes 101, 101.1 . . . 101.n may be illustrated as including executable component 106. The term “executable component” or any equivalent thereof may be the name for a structure that is well understood to one of ordinary skill in the art in the field of computing as being a structure that can be software, hardware, or a combination thereof or which can be implemented in software, hardware, or a combination. For instance, when implemented in software, one of ordinary skill in the art would understand that the structure of an executable component includes software objects, routines, methods, and so forth, that is executed on the computing nodes 101, 101.1 . . . 101.n, whether such an executable component exists in the heap of a computing node 101, 101.1 . . . 101.n, or whether the executable component exists on computer-readable storage media. In such a case, one of ordinary skill in the art will recognize that the structure of the executable component exists on a computer-readable medium such that, when interpreted by one or more processors of a computing node 101, 101.1 . . . 101.n (e.g., by a processor thread), the computing node 101, 101.1 . . . 101.n is caused to perform a function. Such a structure may be computer-readable directly by the processors (as is the case if the executable component were binary). Alternatively, the structure may be structured to be interpretable and/or compiled (whether in a single stage or in multiple stages) so as to generate such binary that is directly interpretable by the processors. Such an understanding of example structures of an executable component is well within the understanding of one of ordinary skill in the art of computing when using the term “executable component”. Examples of executable components implemented in hardware include hardcoded or hard-wired logic gates, that are implemented exclusively or near-exclusively in hardware, such as within a field-programmable gate array (FPGA), an application-specific integrated circuit (ASIC), or any other specialized circuit. In this description, the terms “component”, “agent”, “manager”, “service”, “engine”, “module”, “virtual machine” or the like are used synonymous with the term “executable component.
The processor 102 of each computing node 101, 101.1 . . . 101.n may direct the operation of each computing node 101, 101.1 . . . 101.n in response to having executed computer-executable instructions that constitute an executable component. For example, such computer-executable instructions may be embodied on one or more computer-readable media that form a computer program product. The computer-executable instructions may be stored in the memory 104 of each computing node 101, 101.1 . . . 101.n. Computer-executable instructions comprise, for example, instructions and data which, when executed at a processor 101, cause a general purpose computing node 101, 101.1 . . . 101.n, special purpose computing node 101, 101.1 . . . 101.n, or special purpose processing device to perform a certain function or group of functions. Alternatively or in addition, the computer-executable instructions may configure the computing node 101, 101.1 . . . 101.n to perform a certain function or group of functions. The computer executable instructions may be, for example, binaries or even instructions that undergo some translation (such as compilation) before direct execution by the processors, such as intermediate format instructions such as assembly language, or even source code.
Each computing node 101, 101.1 . . . 101.n may contain communication channels 108 that allow each computing node 101.1 . . . 101.n to communicate with the central computing node 101, for example, a network (depicted as solid line between peripheral computing nodes and the central computing node in
The computing node(s) 101, 101.1 to 101.n may further comprise a user interface system 110 for use in interfacing with a user. The user interface system 110 may include output mechanisms 110A as well as input mechanisms 110B. The principles described herein are not limited to the precise output mechanisms 110A or input mechanisms 110B as such will depend on the nature of the device. However, output mechanisms 110A might include, for instance, displays, speakers, displays, tactile output, holograms and so forth. Examples of input mechanisms 110B might include, for instance, microphones, touchscreens, holograms, cameras, keyboards, mouse or other pointer input, sensors of any type, and so forth.

An at least partially decentralized structure based on decentral identifiers allows for novel methods, apparatuses, systems, computer elements, computer executable instructions and their uses in the battery recycling process, which will be described in the following.
The ID may be a decentralized ID (DID). The ID-based battery passport may be a DID document associated with the DID. The ID-based owner data may relate to at least one battery component such as the battery material, the battery cell, the battery cell pack or the battery. The ID-based battery component data may include an ID associated with at least one battery component such as the battery material, the battery cell, the battery cell pack or the battery and may include authentication mechanisms. The ID-based battery component data may include battery data that is electronically associated with the physical entity of at least one battery component. In this context electronically associated may refer to data that is stored in an producer's repository or wallet. Such data may be securely stored and/or managed on a system associated with a production facility, such as an organizational server or client device. The ID-based battery component data may include a DID, a private key and a public key. The ID-based battery component data may be owned and controlled by at least one producer of the at least one battery component. The at least one producer of the at least one battery component may own and control the DID that represents an identity associated with the at least one battery component as DID subject, a private key and public key pair that are associated with the DID. DID may be understood as an identifier and authentication information may be associated with or uniquely linked to such identifier.
The DID subject may be at least one component of the battery including raw material, intermediate product, component, component assembly or end product. The DID subject may be the raw material, the electrode active material, the battery cell, the battery cell pack, the battery or any combination thereof. The DID owner may be a supply chain participant or a manufacturer such as a chemical manufacturer producing chemicals. The DID owner may be an upstream participant in the supply chain of the chemical manufacturer such as a supplier that supplies raw chemical products or precursors to produce chemicals. The DID owner may be a downstream participant in the supply chain of the chemical manufacturer such as a customer that consumes chemicals to produce the intermediate product, the component, the component assembly or the end product. The DID owner may be any participant of the supply chain including raw chemical product supplier, intermediate chemical products manufacturer, intermediate part manufacturer, component manufacturer, component assembly manufacturer, electrode active material manufacturer, battery cell manufacturer, battery cell pack manufacturer, the battery manufacturer or the end product manufacturer.
The DID may be any identifier that is associated with the DID subject and/or the DID owner. Preferably, the identifier is unique to the DID subject and/or DID owner. The identifier may be unique at least within the scope in which the DID is anticipated to be in use. The identifier may be a locally or globally unique identifier for at least one component of the battery including raw material, intermediate product, component, component assembly or end product or a collection thereof; the chemical manufacturer producing chemicals, the upstream participant in the supply chain of the chemical manufacturer, the downstream participant in the supply chain of the chemical manufacturer or a collection thereof; any participant of the supply chain including raw chemical product supplier, intermediate chemical products manufacturer, intermediate part manufacturer, component manufacturer, component assembly manufacturer or end product manufacturer or a collection thereof.
The DID may be a Uniform Resource Identifier (URI) such as a Uniform Resource Locator (URL). The DID may be an Internationalized Resource Identifier (IRI). The DID may be a random string of numbers and letters for increased security. In one embodiment, the DID may be a string of 128 letters and numbers e.g. according to the scheme did:method name:method specific-did such as did:example:ebfeb1f712ebc6f1c276e12ec21. The DID may be decentralized independent of a centralized, third-party management system and under the control of the DID owner.
The battery passport as DID document 16 may be associated with the DID. Accordingly, the battery passport 16 may include a reference to the DID, which is associated with the DID subject that is described by the DID document. The DID document 16 may also an authentication information such as the public key. The public key may be used by third-party entities that are given permission by the DID owner/subject 14 to access information and data owned by the DID owner/subject 14. The public key may also be used for verifying that the DID owner 14, in fact, owns or controls the DID. The DID document 16 may include authentication information, authorization information e.g. to authorize third party entities to read the DID document or some part of the DID document 16 e.g. without giving the third party the right to prove ownership of the DID.
The battery passport may include one or more representations that digitally link to the product data or chemical product data, e.g. by way of service endpoints. A service endpoint may include a network address at which a service operates on behalf of the DID owner. In particular, the service endpoints may refer to services of the DID owner that give access to battery data. Such services may include services to read or analyze battery data. Battery data may include chemical product declaration data, chemical product safety data, certificate of analysis data, emission data, product carbon footprint data, product environmental footprint data, chemical product specification data, product information, technical application data, production data, material configuration data, recyclate content data or combinations thereof.
The battery passport 16 may include various other information such metadata specifying when the battery passport 16 was created, when it was last modified and/or when it expires or when the at least one component of the battery was manufactured or shipped.
The DID and battery passport may be associated with a data registry node such as a centralized data service system or a decentralized data service system, e.g. a distributed ledger or blockchain 10. Possible blockchain systems include Quorum, Hyperledger Fabric. The distributed ledger or blockchain 10 may be used to store a representation of the DID 14 that points to the battery passport 16. A representation of the DID may be stored on distributed computing nodes of the distributed ledger or blockchain 10. For example, DID hash may be stored on multiple computing nodes of the distributed ledger 10 and point to the location of the battery passport 16. In some embodiments, the battery passport 16 may be stored on the distributed ledger. Alternatively, in other embodiments the battery passport 16 may be stored in a data storage (not illustrated) that is associated with the distributed ledger or blockchain 10.
The distributed ledger or blockchain 10 may be any decentralized, distributed network that includes various computing nodes that are in communication with each other. For example, the distributed ledger 10 may include a first distributed computing node 12.1, a second distributed computing node 12.2, a third distributed computing node 12.3, and any number of additional distributed computing node as illustrated by 12.4, 12.5. The distributed ledger or blockchain 10 may operate according to any known standards or methods for distributed ledgers. Examples of conventional distributed ledgers that correspond to the distributed ledger or blockchain 10 include, but are not limited to, Bitcoin [BTC], Ethereum, and Litecoin.
The example of
The ID may be a unique ID (such as UID) as described in relation to the DID of
In this certificate-based example, the ID-based battery passport data includes one or more certificate(s) associated with the data owner. The certificates may be associated with an identity manager including e.g. a certificate issuing service and/or a dynamic provisioning service providing dynamic attribute tokens (e.g. OAuth Access Tokens). The information required to verify the certificates are provided via an authentication registry associated with the certificate issuing service and/or a dynamic provisioning service. For instance, in the IDSA Reference Architecture Model, Version 3.0 of April 2019, a connector associated with the data owner, a Certification Authority (CA), a Dynamic Attribute Provisioning Service (DAPS) and a connector associated with the data consumer service are used to verify the identity prior to performing a data exchange (not shown). For this purpose, such connectors include one or more certificate(s) such as X.509 certificate(s). This way the connector possesses a unique identifier embedded in a X.509 certificate that identifies the connector instance.
The production facility illustrated in
The physical inputs to the production facility may include materials, such raw materials, intermediate materials or components to be assembled. Raw materials may be virgin or recycled raw materials. In the case of cathode active materials raw materials, such as metals like cobalt, lithium, copper or nickel, may be virgin materials or recycled materials. The physical inputs to the production facility may include discrete battery components, such as battery cells, battery packs or batteries, which may be assembled.
The physical inputs may be associated with the decentral identifier as described in the context of
Based on the provided decentral identifier, battery data associated with such decentral identifier may be accessed. Access may be granted through authentication and authorization based on authentication and authorization information associated with the decentral identifier. Based on the decentral identifier, battery data such as chemical product declaration data, chemical product safety data, certificate of analysis data, emission data, product carbon footprint data, product environmental footprint data, chemical product specification data, product information, technical application data, production data, performance data, quality data, material configuration data, recyclate content data or combinations thereof may be accessed. Battery data may be accessed through a data service requesting access to the battery data associated with each decentral identifier and controlled by a physical input data owner. Data owner may be the producer of the physical inputs. The data service may include computer executable instructions operating in an at least partially decentral computing environment. Such computer executable instructions may be based on a Json Web Token (JWT) including authentication information, authorization information and/or a digital representation pointing to battery data or parts thereof. The digital representation may include an endpoint for data exchange or sharing (resource endpoint) or an endpoint for service interaction (service endpoint), that may be uniquely identified via a communication protocol. The digital representation(s) pointing to battery data or parts thereof may be uniquely associated with the decentral identifier. Battery data may be used for the manufacturing process of the production facility.
The production facility may produce the physical output based on one or more physical input(s). The physical output of the production facility may be associated with a physical identifier. The physical output of the production facility may be physically connected to a physical identifier element as described in the context of
The process steps described above may be executed via an operating system of the production facility. In this embodiment the operating system includes a collector configured to collect battery data and/or physical identifiers as described above. The collector may be configured to collect battery data associated with the component of the battery or battery data associated with the production of the component of the battery, wherein the component of the battery is connected to or comprises the physical identifier.

The decentral identifier may be associated with raw materials data such as a tag for virgin or recyclate material, material properties related to their environmental impact or material properties associated with their origin.
The production of electrode active material may comprise a two-step process: 1) production of precursor material, 2) production of electrode active material. To produce the precursor material, the raw materials may be used as physical inputs. The operating system of the precursor production may access data related to the raw materials based on the decentral identifier e.g. from a raw materials provider. Such data may be used to operate the production. For instance, if the raw materials are recycled materials, production steps purifying the recyclate may be comprised. For instance, if the raw materials are virgin materials, purification steps may be omitted. The precursor material may be formed by co-precipitating the raw materials such as transition metals as carbonates, oxides or preferably as hydroxides that may or may not be basic.
Production data from precursor production may be stored and/or associated with a decentral identifier.

Such precursor material may be associated with a decentral identifier via which data related to the precursor material may be accessible.
The precursor may be mixed with a source of lithium such as, but not limited to LiOH, LhO or U2CO3 and calcined (fired) at high temperatures. Lithium salt(s) may be employed as hydrate(s) or in dehydrated form. The calcination—or firing—generally also referred to as thermal treatment or heat treatment of the precursor—may be carried out at temperatures in the range of from 600 to 1000° C. The thermal treatment may be performed in the heating zone of an oven or kiln. During the thermal treatment a solid-state reaction takes place, and the electrode active material is formed. The electrode active material may be packaged e.g. in powder form.
The produced and packaged electrode active material may be assigned to a decentral identifier and associated information as lined out in
For instance, the packaging line may comprise a detector detecting the physical identifier on each package. Based on such recognition the operating system of the electrode active material production may request to provide a decentral identifier and the provided decentral identifier may be assigned to the physical identifier. In response to the request, the battery passport including the decentral identifier and data related to the electrode active material may be generated. For such generation, data related to the electrode active material as recorded prior and/or during production of the electrode active material may be gathered or accessed. Such data may be provided by the operating system of the electrode material production, or a storage environment connect to the operating system of the electrode material production. This may include data collected and stored during precursor material production.
The data related to the electrode active material may include the identifier of raw materials used to produce the electrode active material. The data related to the electrode active material may include the data related to the raw material as e.g. accessible via the decentral identifier of the raw materials. The data related to the electrode active material may include data related to the material configuration of the electrode active material. The material configuration data may relate to the chemical composition of the electrode active material. The material configuration data may specify at least one constituent of the chemical composition of the electrode active material, such as transition-metal containing constituents. The material configuration data may be associated with the cathode active material. In such an embodiment the material configuration may specify the chemical composition of the cathode active material. Examples are material configurations based on Lithium Nickel Manganese (NCM-type) such as Lithium Nickel Cobalt Manganese Oxide (LiNiCoMnO2), Lithium Iron Phosphate (LPF-type) such as Lithium Iron Phosphate (LiFePO4/C), Lithium Nickel Manganese (LMNO-type) such as Lithium Nickel Manganese Spinel (LiNi0.5Mn1.5O4), Lithium Nickel Cobalt Aluminium (NCA-type) such as Lithium Nickel Cobalt Aluminium Oxide (LiNiCoAlO2), Lithium Manganese (LMO-type) such as Lithium Manganese Oxide (LiMn2O4), Lithium Cobalt (LCO-type) such as Lithium Cobalt Oxide (LiCoO2) or combinations thereof.

For instance, the packaging line may comprise a detector detecting the physical identifier on each package. Based on such recognition the operating system of the electrode production may request to provide a decentral identifier assigned to the physical identifier. In response to the request, the battery passport including the decentral identifier and data related to the electrode active material may be generated. For such generation, data related to the electrode as recorded prior and/or during production of the electrode may be gathered or accessed. Such data may be provided by the operating system of the electrode material production, or a storage environment connect to the operating system of the electrode production.

The embodiments illustrated in
In the example of
The cathode active material producer may store environmental impact data, such as carbon footprint data. The cathode active material producer may store recyclate data from production such as recyclate content of cobalt, nickel, lithium, lead or the like. The cathode active material producer may store data related to production such as production date, site, batch number, producer identity, or the like. The cathode active material producer may store data related to the material configuration or the chemical composition.
The cathode active material producer may provide access to the data related to the electrode active material, that the cathode active material producer provided to a battery producer. Such data sharing may be conducted by way of the decentral network, where the decentral data provider may provide the data and the data consumer may consume the data directly or indirectly.
For accessing in data related to the electrode active material, the service component on the battery producer side may use the public piece of the cryptographic information such as the public key of the electrode active material producer and the battery producer. Based on cryptographic information and an authentication protocol the access by the service component on the battery producer side may be authenticated. In a further step the service component on the battery producer side may request access to the data related to the electrode active material or a subset of such data. The data or the subset may be linked to authorization rules. Based on such authorization rules the access by the service component on the battery producer side may be granted or denied. If access is granted data may be transferred or processed from the service component on the battery producer side as provided by the service component on the electrode active material producer side.
This way a secure and controlled sharing of data may be realized. In particular, the data remains under control by the data owner, while battery data may be shared with selected participants of the network. The battery data including material configuration may be made available to production participants along the value chain. This allows for property tracking and aggregation, appropriate handling in production, testing or quality control.
Via the decentral setup described above different supply chain participants or producers up to end consumers may access data from supply chain participants or producers. Access to such data may include transferring the data to the requester or processing the data and transferring the processed result to the requester. The example of
