Abstract: A novel gel interpenetrating polymer network (IPN) was formed by using PVDF-HFP (poly(vinylidene fluoride)-co-hexafluoropropylene), TEGDA (tetra(ethylene glycol) diacrylate), BPO (benzoyl peroxide) and liquid electrolyte (1 mol·L-1 LiPF6, EC:DEC:EMC=1:1:1). Gel polymer lithium ion batteries were assembled based on the IPN polymer electrolyte. The batteries had good performances in high-current discharge, temperature reliable test and charge-discharge cycling.

Key words: IPN, Gel polymer electrolyte, Polymer lithiumion battery
