Title: Separator for battery and battery using the separator
Inventor: YAMAMOTO KAZUO
IPC: H01M50/489
Filed: 1989-07-27
Abstract: PURPOSE:To make the title separator highly preventive against over heating by cross-linking at least one of laminated polyethylene-based porous films and making at least another one of the film not cross-linked. CONSTITUTION:At least one of not cross-linked polyethylene-based porous film 1 and at least one of cross-linked polyethylene-based porous film 2 are laminated and molded. The cross-linked film 2 is obtained from a non cross-linked film 1 by chemical cross-linking or chemical cross-linking by radioactive ray radiation. The gel ratio after cross-linking is normaly >=15%, preferably 30-90%, in terms of shape retaining property at the time of exposure of the film to high temperature. In this case, when the inner temperature of the battery rises owing to abnormal current, the not cross-linked polyethylene-based porous film 1 is melted and fluidized firstly and since the viscosity of the melt is low, the fine pores of the cross-linked polyethylene porous film are filled and sealed quickly. In this way, ion transfer between both a cathode and an anode is inhibited and thus abnormal current is shut and excessive temperature rise is prevented.
