Vibrational, electrical, and structural properties of PVDF–LiBOB solid polymer electrolyte with high electrochemical potential window
Polyvinylidene difluoride (PVDF)–lithium bis(oxalato)borate (LiBOB) solid polymer electrolytes (SPEs) have been prepared by solution casting. The highest ionic conductivity achieved is 3.4610 −3 S cm −1 . Electrochemical potential window of the SPEs is found around 4.7 V. Interaction between PVDF a...
