Title:
CELL
Document Type and Number:
WIPO Patent Application WO/2000/077867
Kind Code:
A1
Abstract:
Conventionally, the temperature of a cell rises to above 100°C if an inside short-circuit occurs and a large short-circuit current flows and generates heat. Therefore the temperature further rises because of the heat and hence the short-circuit current further increases. A cell according to the invention free from the problem and having an improved performance, comprises an electron conductive material the resistance of which increases with temperature and one of an electrode containing a predetermined amount of a conduction assisting agent, an electrode in which the ratio of the total amount of an electrode conductive material and a conduction assisting agent to that of an active material is a predetermined value, and an electrode in which the ratio of the particle size of a conduction assisting agent to that of an electron conductive material lies in a predetermined range.
