Abstract :
A series of polymers have been investigated in order to determine their suitability as ionically conductive binders of active electrode materials and as hybrid electrolyte matrices in plastic lithium ion rechargeable batteries. Hybrid electrolyte films used in this study have been prepared by solvent casting using a 1:1 w/w mixture of the matrix polymer with 1 M LiPF6 in EC/PC. Based on electrochemical stability, mechanical strength, liquid electrolyte retention, and softening temperature, random copolymers of vinylidene fluoride containing ca. 12 mole % of hexafluoropropylene have been selected for this application
