High voltage stable polymers enable new cathode materials
Compositionally distinct catholytes/anolytes decouple single-chemistry electrolyte problem
Sulfide-based materials are the leading technology for advanced solid-state designs. However, they can be plagued by performance issues. Specifically, interfacial compatibility and resistance can play key roles in limiting performance. Polymers can provide a great enabling function for commercialization of new solid-state cell designs by improving interfacial contact and resistance control during operation. This can change the game for solid-state battery manufacturers, enabling higher levels of performance, stability, and scalability from their cells.
