Title
(EN) NOVEL LITHIUM ION BATTERY AND BATTERY MODULE
(FR) NOUVELLE BATTERIE AU LITHIUM-ION ET MODULE DE BATTERIE
(ZH) 一种新型锂离子电池及电池模组
Abstract
(EN)
Disclosed are a novel lithium ion battery and a battery module, comprising a housing which is internally provided with a positive electrode, a negative electrode and an electrolyte; a partial region of the housing is made of a meltable material; and when the temperature in the housing exceeds a set threshold, the region made of the meltable material on the housing is penetrated, and the electrolyte flows out from the penetration and separates from the positive electrode and the negative electrode. The present invention achieves the prompt separation of an electrolyte from within a novel monomer lithium ion battery when the temperature of the novel monomer lithium ion battery rises abnormally, which effectively prevents the ignition or decomposition of the electrolyte, prevents the novel monomer lithium ion battery from catching on fire and exploding, and prevents a chain reaction of the novel monomer lithium ion battery that is heating up abnormally from damaging other surrounding novel monomer lithium ion batteries.

L'invention concerne une nouvelle batterie au lithium-ion et un module de batterie, comprenant un boîtier qui est pourvu en son sein d'une électrode positive, d'une électrode négative et d'un électrolyte ; une région partielle du boîtier est constituée d'un matériau fusible ; et lorsque la température dans le boîtier dépasse un seuil défini, la région constituée du matériau fusible sur le boîtier est pénétrée, et l'électrolyte s'écoule hors de la pénétration et se sépare de l'électrode positive et de l'électrode négative. La présente invention réalise la séparation rapide d'un électrolyte dans une nouvelle batterie au lithium-ion monomère lorsque la température de la nouvelle batterie au lithium-ion monomère augmente anormalement, ce qui empêche efficacement l'allumage ou la décomposition de l'électrolyte, empêche la nouvelle batterie au lithium-ion monomère de prendre feu et d'exploser, et empêche une réaction en chaîne de la nouvelle batterie au lithium-ion monomère chauffant de manière anormale d'endommager d'autres nouvelles batteries au lithium-ion monomère environnantes.
