Abstract

A acrylonitrile (AN)-methyl acrylate (MMA)-methoxy polyethylene glycol(350) monoacrylate (MPGA)-lithium acrylate (LiAc) tetra-copolymer was synthesized by emulsion polymerization, and phase inversion technique was adopted to prepare the as prepared polymer based microporous membrane. The gel polymer electrolytes (GPEs) were obtained by soak the as-prepared microporous membrane into 1M LiPF 6/ (EC (ethylene carbonate) + DEC (diethylene carbonate)) (1:1 vol) electrolyte. FTIR, NMR and TGA/DSC measurements are used to character the components and structure of the polymer. The GPE's ionic conductivity exceeds 3.0?0 -3S/cm at ambient temperature, and this system also shows a sufficient electrochemical stability with a decomposition voltage as much as 6.0V vs Lithium(Li)/Li+ to allow far wider operation in the rechargeable lithium-ion polymer batteries. What's more, this membrane also shows good characters in battery's charge-discharge cycles.
