This application is related to and claims priority under 35 U.S.C. § 119(e) from U.S. Patent Application No. 63/614,269, filed Dec. 22, 2023 titled “Lithium Dispenser System for Manufacture of an Electrode,” the entire contents of which is incorporated herein by reference for all purposes.
Various embodiments described herein relate to the field of solid-electrolyte containing primary and/or secondary electrochemical cells, separators, electrodes, and electrode materials, and the corresponding methods of making and using the same.
The evolution of hybrid and electric automobiles and other battery powered vehicles, and more generally battery-powered devices, is creating needs for battery technologies with improved reliability, capacity, thermal characteristics, lifetime, and recharge performance, among other things. Currently, although lithium-based and other solid-state battery technologies offer potential improvements in safety, packaging efficiency, and enable new high-energy chemistries as compared to other types of batteries, improvements in lithium-based and other solid-state battery technologies are needed, including advances in high volume production and cost reductions to the same.
It is with these observations in mind, among others, that various aspects of the present disclosure were conceived.
One aspect of the present disclosure relates to a system for manufacturing a battery electrode. The system including a feeder spool containing a conductive foil layer and an interleaf layer, an application roller receiving the conductive foil layer and the interleaf layer from the feeder spool, the application roller applying the conductive foil layer onto a solid-state electrolyte (SSE) layer of an electrode stack, and a rewind spool containing the remaining interleaf layer after the conductive foil layer is applied onto the SSE layer. The conductive foil is deposited onto the SSE layer through a gravitational force on the conductive layer and/or a surface energy between the conductive foil layer and the SSE layer, the rewind spool providing a pulling force to remove the interleaf layer as the conductive layer is deposited onto the SSE layer by the application roller.
Another aspect of the present disclosure relates to a method for manufacturing a battery electrode. The method may comprise the operations of feeding an interleaf layer comprising a polymer material from a feeder spool, around an application roller, and to a rewind spool, the feeder spool containing a conductive foil layer and the interleaf layer in a layered configuration, rotating the rewind spool to generate a pulling force on the interleaf layer to apply, at the application roller, the conductive foil layer onto a solid-state electrolyte (SSE) layer of an electrode stack through a gravitational force on the conductive layer and/or a surface energy between the conductive foil layer and the SSE layer, the pulling force removing the interleaf layer as the conductive layer is deposited onto the SSE layer by the application roller, and passing, while rotating the rewind spool, the conductive foil layer and the SSE layer through a pressing device.
Lithium-based rechargeable batteries are popular to power many forms of modern electronics and have the capability to serve as the power source for hybrid and fully electric vehicles. Traditional electrode manufacturing for lithium-based rechargeable batteries can be a time-consuming and inefficient process, however. To manufacture a graphite anode, for example, a graphite slurry is produced that includes graphite components, binders, and some kind of solvent that is then applied to a metal foil, such as a copper foil, by a process of extrusion, rolling, or tape-casting, depending on selected process and solvents used. After application, the coated graphite mixture is dried by evaporation of solvents, such as by running the coated slurry through an oven or other drying machine. Cathode construction may occur in a similar manner with an aluminum foil used.
In an alternate approach, the electrode may be comprised of solid-state components layered in an electrode configuration. In particular, an electrode laminate for a battery may include a solid-state separator layer in place of a traditional separator layer/liquid electrolyte used in conventional liquid electrolyte battery architectures. Typical solid-state separator layers use some type of polyethylene material with a ceramic coating to separate the anode from the cathode and prevent shorts within the battery. The stack electrode may also include the solid-state electrolyte separator layer to allow the flow of electrons between the cathode and anode through the layer, without the use of a liquid electrolyte. Regardless, each of the multiple steps to produce the battery stack may introduce inefficiencies or opportunities for flaws to in the battery design, resulting in shorter battery life or potential for a short within the battery itself. For example, one or more layers of the battery stack may be quite delicate and may tear or break if handled roughly during construction of the electrode stack. These tears or breakages within the layers of the electrode stack can lead to an inefficient battery. As such, tremendous care is typically required in the manufacturing and handling of battery electrodes to prevent damaging one or more layers of the electrode stack.
The term “battery” in the art and herein can be used in various ways and may refer to an individual cell having an anode and cathode separated by an electrolyte, solid or liquid, as well as a collection of such cells connected in various arrangements. A battery or battery cell is a form of electrochemical device. Batteries generally comprise repeating units of sources of a countercharge and electrode layers separated by an ionically conductive barrier, often a liquid or polymer membrane saturated with an electrolyte. These layers are made to be thin so multiple units can occupy the volume of a battery cell, increasing the available power of the battery cell with each stacked unit. Although many examples are discussed herein as applicable to a battery cell, it should be appreciated that the systems and methods described may apply to many different types of batteries ranging from an individual cell to batteries involving different possible interconnections of cells, such as cells coupled in parallel, series, and parallel and series. For example, the systems and methods discussed herein may apply to a battery pack comprising numerous cells arranged to provide a defined pack voltage, output current, and/or capacity. Moreover, the implementations discussed herein may apply to different types of electrochemical devices such as various different types of batteries and solid-state batteries of various possible chemistries, to name a few. The various implementations discussed herein may also apply to different structural battery cell arrangements such as button or “coin” type batteries, cylindrical battery cells, pouch battery cells, and prismatic battery cells.
Aspects of the present disclosure involve systems and methods of producing an electrode, which may be for a battery that includes a solid-electrolyte separator layer. Further, the present disclosure involves systems and methods for reducing or preventing damage to one or more of the layers within the electrode stack, which may include one or more anode layers, one or more cathode layers, one or more solid-electrolyte separator layers, etc., during the manufacturing process. For example, a layer of lithium material may be used as a conductive layer of the stack. However, such a lithium layer may be very fragile and susceptible to tearing, breaking, or other damage during the manufacturing process (e.g., the layering of materials to create the electrode stack). To address the observed instabilities of solid-state electrode manufacturing, aspects of the present disclosure involve utilizing one or more spools and/or rollers for the gentle application of a lithium layer onto a separator layer in an electrode stack of a solid-state battery cell to prevent or minimize damage to the fragile conductive layer. Further, although described herein as applying to a lithium layer, it should be appreciated that the systems and methods discussed herein may apply to any material or layer of a battery cell. The system including spools and/or rollers described herein may reduce one or more pulling forces on a fragile layer of the electrode stack (such as a lithium conductive layer) during manufacturing to protect the layer from tearing or suffering other mechanical flaws in the layer. The electrode laminate discussed herein may then be utilized in any type of battery or electrochemical cell, including solid state, semi-solid state, or liquid-based batteries.
In one example, an electrode of a battery may comprise a stack of a center electrode layer or layers between two layers of a solid-state electrolyte (SSE) material. However, in some implementations, the conductive center electrode foil may be comprised of a fragile material that may be damaged or tear easily when manipulated. Thus, application of the conductive center electrode onto or between the SSE layer may include a process that reduces the manipulation and forces applied to the layer. In one instance, application of the conductive foil within the conductive stack may include rolling the foil onto an SSE layer by a gentle roller applicator while reducing or minimizing a pulling force on the conductive foil as compared to some previous implementations.
In particular, a feeder spool of alternating layers of a lithium or lithium alloy foil and a polymer interleaf material may be unrolled to provide the conductive foil and interleaf stack combination to an application roller. The application roller may then roll or otherwise apply the conductive foil onto an SSE layer of the electrode stack prior to the SSE layer being passed through a calender or other pressing device (generally utilized to densify or laminate one or more of the layers of the electrode, including the center conductive foil layer). An interleaf rewind spool may collect the remaining interleaf material from the conductive foil/interleaf combination once the conductive foil is deposited onto the SSE layer. In some instances, the interleaf rewind spool may be controlled or otherwise rotated to gently pull the interleaf material away from the conductive foil once the foil comes into contact or is otherwise deposited onto the SSE layer. The conductive foil may adhere to the SSE layer through a combination of a gravity force pressing the conductive foil onto the SSE layer and/or surface energy between the conductive foil and the SSE layer, thereby allowing the interleaf rewind spool to pull the interleaf material from the combination. The control of the rotation of the interleaf rewind spool may be such as to provide enough of a pulling force to rotate the feeder spool and the application roller without ripping or tearing the conductive foil as the foil is rolled onto the corresponding SSE layer. Through this combination of spools and rollers, a constant application of the conductive foil into the electrode stack may be accomplished that reduces the likelihood of tearing of the conductive foil during the manufacturing process.
These and other manufacturing systems and methods are described herein for generating a solid-electrolyte containing electrode laminate for use in a battery configuration.
To produce the solid-electrolyte electrode laminate 124 for the battery cell, two different sheets of the SSE 116 may be oriented such that the SSE layers are facing each other with the center conductor layer 110 between the two SSE sheets. When a lithium foil center conductor is positioned between SSE (separator) layers, the electrode stack may be considered a double separator sided anode. The formed electrode stack may then be used with additional cathode layers and current collectors in a battery cell, which may include multiple layers of such arrangements. The SSE layer 116 may comprise, in some implementations, a sulfide-based material. The SSE layer 116 may also include a binder solution and/or a solvent prepared in a slurry form that is mixed and dried. Each of the SSE layers 116 may be between 30-100 microns thick, although other thicknesses may be used. In one implementation, the center electrode 110 may include a lithium foil and the layers may be arranged in an [SSE-Lithium-SSE] stack. In other implementations, the center electrode may be a lithium alloy such as Li-Al (Lithium-Aluminum), Li-Mg (Lithium-Magnesium), Li-In ((Lithium-Indium). The lithium content of the center electrode alloys may be, in some examples, 5% to 99.9%, 10% to 99%, 20% to 98%, or 50% to 95%. In still another implementation, the center electrode may be a cathode comprising conductive materials, such as gold, silver, cadmium, etc. In general, any type of conductive material arranged in one or more layers may be utilized as the center electrode layer for the solid-electrolyte containing electrode.
In this implementation, the layers forming the electrode stack 124 are fed between the calender press 118 in an SSE-Lithium-SSE stack to laminate and/or densify the center electrode layer 110 (also referred to herein as the “conductive layer”) to the SSE layers 116. The calender press 118 may comprise a first roller 120 and a second roller 122 with a gap 126 between the rollers. As the electrode stack 124 is fed between the rollers 120, 122 through the gap 126 between the rollers, the rollers exert a force, which may be considered in some instances a compressive force, on the stack to press the layers together, thereby reducing the porosity of the materials within the stack (or increasing the density of the materials), enhancing material contact, and/or causing some layers to bond. In general, the respective rollers 120, 122 of the calender press 118 are spaced apart a distance less than the pre-calendered stack thickness such that pressure on the stack being fed between the calender rollers may reduce the porosity of the materials within the stack (thereby increasing the density of the SSE layers 116), enhance material contact between the layers, and/or cause the SSE layers to laminate or otherwise adhere to the center conductor layer 110.
The pressure applied to the stack 124 may correlate to a spacing 126 between the first roller 120 and the second roller 122, which may be adjustable by a controller 112, or manually prepositioned and adjustable. For example, one or both of the calender rollers 120, 122 of the press 118 may be adjustable to increase or decrease the spacing between the rollers based on the overall thickness of the electrode stack 124 or based on the thickness of one or more of the individual layers. The spacing 126 may be input to the controller 130, such as through a user input device connected to the controller, to set the spacing. In another implementation, one or more sensors may be associated with the calender press 118 and provide an output to the controller 130 which may control the spacing 126 in response. For example, the temperature of one or more of the layers of the electrode laminate 124 may affect the densification or adhesion of the layers. Thus, the temperature of the layers may be received from a sensor and the spacing of the rollers 120, 122 may be adjusted based on the received electrode temperature. Alternatively or in conjunction, the temperature of the rollers 120, 122 themselves may be adjusted or altered to change both the amount of densification of the layers of the electrode 124 and/or the adhesion of the layers. Other sensor inputs or other types of inputs may also be received at the controller 130 and used to adjust the calender spacing 126.
Application of the center electrode 110 onto the SSE layer or layers 116 of the electrode stack 124 may occur prior to the pressing of the stack by the calender press 118 such that the center electrode may be at least partially laminated to the SSE layers 116 of the stack. However, as mentioned above, the conductive foil 110 of the center electrode may be delicate and break or tear easily. Thus, the center electrode layer 110 may be applied to an SSE layer 116 of the electrode 124 through an application system 128 that may include unspooling a center electrode foil onto one of the SSE layers.
In general, however, the application roller 104 may have various orientations, sizes, and material for applying sufficient pressure to press the conductive foil 110 onto the SSE layer 116 for transfer of the conductive foil to the SSE layer. For example, the application roller 104 may be constructed of a stainless steel material or other hard material that provides a higher pressing force against the conductive foil 110 as the foil is pressed onto the SSE layer 116 by the roller. An application roller 104 constructed from a softer material, such as a silicon, may provide a lesser pressing force onto the conductive foil 110 at the point of transfer to the SSE layer 116 due to the pliability of the roller. An application roller 104 with a softer or more pliable material may be located more vertically with respect to the lower roller 122 of the calender press 118 than an application roller with a harder material. As explained in more detail below, the application roller 104 may apply the conductor foil 110, after separation from the interleaf 108, to an SSE layer 116 prior to the stack 124 being passed through the calender press 118. Although illustrated as being applied to the lower SSE layer 116, it should be appreciated that the conductor foil 110 may alternatively be applied to the upper SSE layer.
At the application roller 104, the conductor foil 110 is deposited onto the SSE layer 116. As the conductor foil 110 is placed on the corresponding SSE layer 116 by the application roller 104, the conductor foil is also separated from the interleaf 108. To avoid damage to the delicate foil 110, the combined interleaf and foil is withdrawn from the feeder spool 102 by pulling only on the interleaf 108. More particularly, the interleaf 108 may be attached to an interleaf rewind spool 106. The spool 106 is powered such that rotation of the interleaf rewind spool pulls the interleaf material 108 away from the conductor foil 110 as the foil is deposited onto the SSE layer 116. This has the effect of withdrawing the combined foil 110/interleaf 108 material from the feeder spool 102 without putting direct force on the delicate conductor foil 110. Where the foil 110 engages the SSE 116, the interleaf 108 is pulled away from the foil separating the interleaf from the foil and the interleaf is then collected at the rewind spool 106. As such, the rotation of the interleaf rewind spool 106 may aid in pulling the foil 110 from the feeder spool 102 while also separating the interleaf 108 from the conductor foil 110 in a manner that reduces or prevents tearing of the conductor foil for uniform (undamaged) application to the SSE layer 116. In one instance, the feeder spool 102 may rotate in a clockwise direction and the application roller 104 and the interleaf rewind spool 106 may rotate counter-clockwise. The feeder spool 102 and the application roller 104 are not necessarily powered because, as noted above, the material is withdrawn from the feeder spool 102 by way of the rewind spool 106 pulling only directly on the interleaf 108. Thus, the feeder spool 102 and the application roller 104 may be allowed to rotate freely in response to the rotation of the interleaf rewind spool 106. In one implementation, the speed at which the rewind spool rotates may be related to the rotation speed of either the calendar rollers 120,122 and/or the feeder spool 102 to ensure that the components of the stack do not bunch up prior to entering the calendar press 118. In general, the rewind spool 106 may be controlled to maintain a continuous feed of the foil onto the SSE layer as the SSE layer is pulled through the calendar press 118 such that the rotation speed of the rewind spool is based on the speed of the combined electrode through the calendar press. In some particular examples, the linear speed of the foil 110 may be 1 meter/min up to 100 meters/min.
Inset 132 of
In another implementation, the feeder spool 102 may be loaded with an interleaf 108/conductive foil 110 combination that includes several meters (or some other sufficient length) of the interleaf layer at the end of the spool that can be pulled from the feeder spool before a conductive foil is exposed. In the manner as described above, the single interleaf layer 108 at the end of the feeder spool 102 may be sufficient to feed the interleaf layer around the application roller 104 and wound around the interleaf rewind spool 106 to begin the process of pulling the combination of interleaf 108/conductive foil 110 from the feeder spool. Regardless of if the conductive foil layer is removed or if the feeder spool 102 is loaded with a portion of a single interleaf layer 108 at the end of the feeder spool, enough interleaf layer may be fed to the interleaf rewind spool 106 to provide a tension on the interleaf layer to rotate the feeder spool 102 and/or the application roller 104.
At step 208, the interleaf rewind spool 106 may be rotated to begin to spool the interleaf layer 108 onto the spool while pulling the interleaf 108/conductive foil 110 from the feeder spool 102 around the application roller 104. As explained above, as the interleaf 108/conductive foil 110 combination is pulled around the application roller 104, the conductive foil layer may contact a corresponding SSE layer 116 prior to being passed through the calender press 118. More particularly, the rollers 120, 122 of the calender press 118 may be rotated at the same time that the interleaf rewind spool 106 is rotated such that the conductive foil 110 may be applied to the corresponding SSE layer 116 as the SSE layer is fed into the calender press. The rotation of the interleaf rewind spool 106 causes a pulling force on the interleaf layer 108, which in turn causes rotation of the application roller 104 and the feeder spool 102. As also explained above, at the point where the conductive foil 110 comes into contact with the SEE layer 116, the application roller 104, through gravity and an adhesion property or surface energy between the conductive layer 110 and the SSE layer 116, may deposit the conductive layer onto the SEE layer. The conductive foil 110 may adhere to the SSE layer 116 with a surface energy that is more than the surface energy between the conductive foil and the interleaf 108, which causes the conductive foil 110 to separate from the interleaf. The conductive foil 110, now adhered to one of the SSE layers 116, is passes through the calender rollers 120, 122, where the stack 124 is laminated to form a densified SSE-Conductive Layer-SSE electrode stack. The application of the conductive foil 110 onto the SSE layer 106 may therefore occur through the pulling tension on the interleaf layer 108 and not the conductive layer 110. Rather, the conductive foil 110 may be applied to the SSE layer 116 through the application roller 104 lightly pushing or otherwise placing the conductive layer onto the SSE layer. This may reduce a mechanical strain on the conductive layer 110 and prevent or reduce damage to the fragile conductive layer during the electrode manufacturing process.
At step 210, the interleaf rewind spool 106 may be controlled to continue rotation, thereby causing pulling of the conductive foil 110/interleaf layer 108 from the feeder spool 102 and around the application roller 104. As best illustrated in
