Abstract

PURPOSE:To prevent the heating and explosion in case of a short-circuit without injuring the battery performance, by bonding previously pulverized polyethylene powder onto the separator of the captioned battery which uses non-aqueous electrolytic solution. CONSTITUTION:A separator is made of non-woven polypropylene cloth or non- woven polypropylene cloth mixed with glass fiber. About 5-40% of pulverized polypropylene powder is previously bonded onto the separator. When short-circuit occurs across both electrodes in this battery, the inside of this battery is heated by the short-circuit current. When the inside temperature the battery reaches about 110-120 deg.C, the pulverized polypropylene powder bonded onto the separator is melted and the conductivity of the separator is injured. Consequently, the internal resistance of the battery suddenly increases and the short-circuit current thereof suddenly decreases. Also, the battery temperature is lowered in proportion to the decrease of the short-circuit current and the possibility of explosion is eliminated.

That is, by immersing the separator 5 in an aqueous polyethylene emulsion and then taking it out and drying it, polyethylene fine powder with a particle size of about several microns is attached to the separator 5.

The short-circuit current generates heat inside the battery, gradually increasing the temperature. When the internal temperature of the battery reaches a certain temperature of about 110 to 120°C, the fine polyethylene powder attached to the separator 5 dissolves. As the polyethylene fine powder dissolves, the electrical conductivity of the separator 5 is significantly impaired, and the separator 5 becomes a film with almost no electrical conductivity. the result,
The internal resistance of the battery increases rapidly, and as a result, the battery current suddenly decreases, and the battery temperature no longer reaches an upper limit.In fact, the battery temperature decreases as the short-circuit current decreases, and the battery temperature decreases as the short-circuit current decreases. There is no danger of explosion.
