METHOD OF PRODUCING A POROUS POLYPROPYLENE RESIN FILM, CELL SEPARATOR, AND CELL |
摘要 |
Regarding a polypropylene series resin porous film having a polypropylene series resin as the main component, so as to exert excellent slipping ability and processability when used as a battery separator, a polypropylene series resin porous film fabricated in such a way that the coefficient of static friction against film is greater than the coefficient of static friction against SUS is proposed. |
