We also discuss how polymer materials have been designed to create stable artificial interfaces and improve battery safety. The focus is on these design principles applied to advanced silicon, lithium-metal and sulfur battery chemistries. Polymers are ubiquitous in batteries as binders, separators, electrolytes and electrode coatings.
(2) Thus, well-known polymers such as poly (vinylidene fluoride) (PVDF) binders and polyolefin porous separators are used to improve the electrochemical performance and stability of the batteries. Furthermore, functional polymers play an active and important role in the development of post-Li ion batteries.
The polymeric backbone as well as the conducting and binding materials (multi-walled carbon nanotubes and PVDF, respectively) revealed no significant influence on the electrochemical behavior and, as a consequence, the polymers were employed as active material in a composite electrode for lithium organic batteries.
When organic solvents are applied in the electrode processing or the battery electrolyte, fluorinated polymers, e.g., poly (tetrafluoroethylene) (PTFE) and poly (vinylidene difluoride) (PVDF), are mostly used due to their electrochemical stability, binding capability, and electrolyte absorption ability.
In summary, several polymers have been applied in lithium batteries. Starting from commercial PP/PE separators, a myriad of possible membranes has been published. Most publications focus on increasing the ionic conductivity and the lithium-ion transference number.
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.
