摘要：
A material for solid polymer electrolyte, made of a polyether polymer having a moisture content in the range of 400 to 5,000 ppm by weight. A formed solid polymer electrolyte, which is made by mixing the material for solid polymer electrolyte together with an electrolyte salt compound soluble in the polyether polymer, has good ionic conductivity and high mechanical strength. A polyether polymer having a moisture content not larger than 0.04% by weight and a toluene-insoluble content not larger than 5% by weight. This polyether polymer gives a formed solid polymer electrolyte having a smooth surface.
