Lithium ion secondary battery

摘要

A multilayer electrode battery which restrains temperature rise produced by an internal short circuit and has a compact size and a large battery capacity. The battery is a multilayer electrode battery which uses an electrode formed by providing positive temperature coefficient characteristics to at least one of an active material and an electronic conductive material in contact with the active material, and a collector of at least one of a positive electrode and a negative electrode, and which has a plurality of layers of multilayer electrode bodies.
