Abstract The tertiary copolymer electrolytic film is prepared by adding polymer material, which includes meta-fluoroethylene-tetrafluoroethylene-hexafluoropropylene and plasitisizer and capable of forming gel together with electrolytic liquid and crosslinking and grafting electrolyte film to form polymer electrolyte film, into electrode. During the process, powder, granular of fibrous additive and film support may be added so that the electrolyte liquid forms gel without dendrite formed and leakage of electrolyte liquid. The cell is used in portable electronic equipment.
