Polymers play a crucial role in improving the performance of the ubiquitous lithium ion battery. But they will be even more important for the development of sustainable and versatile post-lithium battery technologies, in particular solid-state batteries.
In recent years, the demand for higher energy density in polymer batteries has increased, which has reduced the thickness of the polymer electrolyte film, thus increasing safety risks. On the cathode material side, the nickel-rich layered cathode material experiences a little increase in volume , .
Furthermore, this method improves the performance of polymer electrolyte batteries by enclosing self-healing additives in the shell, which aids in mending any damage that may arise to the electrolyte interface and thus greatly enhances the cycling stability of the batteries.
Furthermore, functional polymers play an active and important role in the development of post-Li ion batteries. In particular, ion conducting polymer electrolytes are key for the development of solid-state battery technologies, which show benefits mostly related to safety, flammability, and energy density of the batteries.
Moreover, polymers also play critical roles in binders, separators, and electrolytes instead of being merely limited to the cathode due to their excellent chemical stability, film-forming ability, and processability as demonstrated in Figure 1. [36, 45] Multifunctional roles of polymers in addressing current challenges of lithium–sulfur batteries.
Some tough challenges for polymer materials related to batteries include developing fast Li + transport at room temperature, further stabilizing high-capacity electrodes, and improving the electrochemical stability of high-voltage cathode materials.
