The present disclosure relates to polymers and additives that may be used in energy storage applications, and more specifically, in liquid and solid state electrolytes. The present disclosure further relates to batteries and capacitors containing the electrolytes.
Renewable sources of energy (e.g., photovoltaic, eolic, and the like) that do not rely on coal, petroleum products, or natural gas are seeing increased use in a variety of applications based on their substantially reduced environmental impact. As efforts to reduce greenhouse gas emissions become even more critical, their use is expected to increase further. However, even though renewable energy sources are naturally replenishing (i.e., virtually inexhaustible), they are limited in the amount of energy that is available per unit of time. As a result, there is a need to develop new, highly efficient energy storage systems that meet the technological demands of both existing and developing applications. These storage systems should also be safe and non-toxic.

Energy storage is a field with a tremendous push for innovation due to the use of renewable sources of energy like photovoltaic and eolic that do not rely on coal, petroleum products or natural gas—fossil fuels that are major greenhouse gases contributors. These increasingly used renewable energy sources need electrical storage systems capable of storing the energy produced in a non-continuous fashion and releasing it when needed. In the energy storage field, rechargeable batteries are of special importance due to the portable devices market. Cost and performance of new advanced batteries are key to extend the usage of new energy sources. Applications such as hybrid and electric cars, smartphones, and wearables need batteries with higher energy and power densities, shorter charge cycles and safer systems. Currently, lithium ion batteries are the most widely used type of battery in those applications thanks to the lightness and high energy density of lithium, which confers important advantages to this type of batteries compared to Pb-acid, Ni—Cd or NiMH ones. Nevertheless, commercially available lithium ion batteries have important limitations such as safety hazards, self-discharge, and environmental toxicity among others. Some causes of these limitations are lithium metal dendrite growth that can cause short circuits and flammable organic solvent usage that can produce toxic compounds and catch fire easily.
In contrast, solid state batteries offer particular advantages. They do not contain toxic and flammable liquid organic solvents, which translates to increased safety and reduced toxicity. In addition, they have potentially higher energy and power density. The main challenge for solid state electrolytes is the ionic conductivity since ions move slower in solids than they perform in the liquid-based organic solvents. Ionic movement through the electrolyte is needed to move the electron flow in the external component of the battery. In polymer-based electrolytes, crystallinity and polymer composition determines the pace at which ions move between electrodes.
Poly(ethylene oxide) (PEO) has been considered the gold standard of polymer based solid state electrolytes due to its intrinsic ionic conductivity at high temperatures and its ability to dissolve lithium salts. Nevertheless, PEO has low ionic conductivities at room temperature (10−5 S/cm), far from the lithium ion battery ionic conductivities and what is desirable for commercial applications (10−3 S/cm).
Other compounds that have been tested and found successful for one or multiple property requirements are methacrylates, poly ethers, fluoro organic compounds, poly acrylonitrile, polystyrene, poly vinyl pyrrolidone, polypyrrole, polyacrylic acid, polycyanoacrylates and analogue molecules. Additives such as succinonitrile have also demonstrated ionic conductivity enhancement.
In addition to the material composition, the polymer structure plays an important role in the system performance. Some approaches consist of copolymer electrolytes with one type of material providing structural integrity and another one providing ionic conductivity. Others use additives intercalated in the polymer to enhance the ionic conductivity.
The challenge for solid state batteries consists of finding a system with properties that fill all the requirements without sacrificing a particular one. Those requirements include: high ionic conductivity (measured in S/cm), high energy and power density (in Wh/kg and W/cm2), high stability, high capacity retention (in % of retention after x number of cycles), non-flammability, high thermal stability, good mechanical properties to avoid dendrite formation (shear modulus in Pa), flexibility, being easy to produce and cheap (in $/kWh), and having high voltage (in V).
