摘要： 采用PVDF-HFP (poly (vinylidene fluoride)-co-hexafluoropropylene)、TEGDA(tetra (ethylene glycol) diacrylate)、BPO(benzoyl peroxide, 过氧化苯甲酰)和电解液(1 mol·L-1 LiPF6, EC:DEC:EMC=1:1:1)作为组分形成凝胶态IPN(interpenetrating polymer network, 聚合物互穿网络)聚合物电解质, 并用一种简便的方法制备了聚合物锂离子电池.该凝胶态聚合物锂离子电池具有较好的倍率放电性能、高低温放电性能和循环寿命.

关键词: IPN, 凝胶态聚合物电解质, 聚合物锂离子电池

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
