BATTERY
Document Type and Number:
Japanese Patent JP3729115
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To secure safety by resolving a conventional separator displacement problem to improve a vibration test and a storage characteristic by painting and forming an endothermic resin film having porosity on an electrode and by keeping it as a heat resisting resin by restraining temperature rise by the endothermic property and by blocking oxygen by a shutter effect and to improve workability in a group composition to improve a yield.
SOLUTION: The negative electrode of this battery is composed by forming an active material layer 2 formed with graphite and a resin on copper foil 3 of a collector and by forming a porous resin film on the active material layer.
