Abstract
(EN)
Disclosed is a nonaqueous electrolyte battery comprising a positive electrode containing a positive electrode active material capable of absorbing/desorbing lithium ions, a negative electrode capable of absorbing/desorbing lithium ions, a separator arranged between the positive electrode and the negative electrode, and a nonaqueous electrolyte solution. The exothermic onset temperature of the positive electrode is not less than 180˚C, and the separator contains heat-resistant fine particles and a thermoplastic resin. The heat-resistant fine particles contain particles having a diameter not more than 0.2 &mgr;m and particles having a diameter not less than 2 &mgr;m respectively in an amount of not more than 10% by volume. The separator causes a shutdown over a temperature range of not less than 100˚C and not more than 150˚C.

La présente invention concerne un accumulateur à électrolyte non aqueux comportant une électrode positive contenant un matériau d'électrode positive capable d'absorption/de désorption d'ions de lithium, une électrode négative contenant un matériau d'électrode négative capable d'absorption/de désorption d'ions de lithium, un séparateur disposé entre l'électrode positive et l'électrode négative, et une solution électrolytique non aqueuse. La température de démarrage de réaction exothermique de l'électrode positive est égale ou supérieure à 180°C, et le séparateur contient des particules fines résistantes à la chaleur et une résine thermoplastique. Les particules fines résistantes à la chaleur contiennent des particules ayant un diamètre égal ou inférieur à 0,2 &mgr;m et des particules ayant un diamètre égal ou inférieur à 2 &mgr;m respectivement en une quantité égale ou inférieure à 10% en volume. Le séparateur entraîne un arrêt sur une plage de température comprise entre 100°C et 150°C.
