Title:
NONAQUEOUS BATTERY
Document Type and Number:
WIPO Patent Application WO/1996/023324
Kind Code:
A1
Abstract:
A nonaqueous battery which comprises unit battery layers in a battery jar, each unit battery layer composed of a positive electrode plate having a positive electrode active material only on one side of a collector foil, a negative electrode plate having a negative electrode active material only on one side of a collector foil and a separator, and in which a surface of the positive electrode plate having thereon the positive electrode active material and a surface of the negative electrode plate having thereon the negative electrode active material face each other through the separator, and a surface of the positive electrode plate not having thereon the positive electrode active material and a surface of the negative electrode plate not having thereon the negative electrode active material face each other through an insulating film. According to the invention, safety of the battery is ensured since rapid temperature rise is suppressed inside even in the event of abnormal heating from outside, crushing of the battery in a direction of lamination, or short circuit between the positive electrode active material and the negative electrode due to nailing and the like.
