摘要： A homogeneous solid polymer alloy electrolyte comprises a total 100 weight % of mixture of (a) from 5 to 90 weight % comprising one of polyacrylonitrile-based (PAN-based) solid polymers and poly(methyl methacrylate)-based (PMMA-based) solid polymers which have superior adhesion and ion conductivity, (b) from 5 to 80 weight % comprising one of poly(vinylidene fluoride)-based (PVdF-based) solid polymers and the PMMA-based solid polymers which have superior compatibility with an organic solvent electrolyte, (c) from 5 to 80 weight % comprising one of poly(vinyl chloride)-based (PVC-based) solid polymers and the PVdF-based solid polymers which have superior mechanical strength. The solid polymer alloy electrolyte has superior ion conductivity, compatibility with an organic solvent and mechanical strength. A lithium polymer battery manufactured by making the composite anode and cathode using the solid polymer alloy electrolyte, and stacking the solid polymer alloy electrolyte and the composite anode(cathode) in several times, has excellent adhesion, mechanical stability, low/high temperature characteristics, high rate discharge, charge/discharge properties, and battery capacity and battery cycle life characteristics.
