Abstract
PURPOSE:To obtain a polymer electrolyte showing good lithium ion conductivity even at room temperature by using a specified polymer prepared by the addition of polyether glycol to polyglycerine as an organic polymer for polymer electrolyte. CONSTITUTION:A polymer, as shown in the formula I, prepared by the addition of polyether glycol to polyglycerine is used as an organic polymer for a polymer electrolyte. In the formula I, R shows polyethylene glycol, polypropylene glycol and the like, and n is 50 or less. Since polyether glycol which is liquid at room temperature and has good ion condcutivity is added to the side chain, the polymer functions as a good lithium ion condcutor, and the crystallinity of the polymer is lowered and the crystallization at room temperature is difficult to arise. The polymer electrolyte showing good lithium ion conductivity even at room temperature is obtained.
