Improved high-temperature performance of lithium-ion batteries through use of a thermally stable co-polyimide-based cathode binder

The effects of a thermally stable co-polyimide-based polymeric binder on the performance of a cathode electrode are investigated. The introduction of co-polyimide (P84) into a conventional polymeric binder system based on polyvinylidene fluoride (PVdF) enhances the cycle performance under high-tempe...
