摘要: A thin battery comprising a battery body and a flexible package. The battery body comprises a laminate or coil including a positive plate, a negative plate, and a separator between them; and a plurality of leads connected to the positive and negative plates. The package, in which the battery body is placed, is charged with electrolyte and sealed in such a manner that the inner pressure is lower than atmospheric pressure and higher than the vapor pressure of the electrolyte. This battery is kept from generation of gas in the package during storage at high temperature and from the increase in the inner pressure due to expansion of gas.

摘要: 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.
