Abstract
(EN)
Disclosed is a battery. A first current collector in the battery is in contact with a battery shell, so that some heat generated by a cell can be directly conducted to the battery shell through the first current collector. A heat conductivity coefficient of a current collector is very large, so the heat dissipation performance of a cell is improved. The battery comprises: a battery shell, a first current collector, a diaphragm and a second current collector, wherein the first current collector, the diaphragm and the second current collector are stacked and arranged inside the battery shell, the first current collector and the second current collector are different in polarity, and the first current collector is in contact with the battery shell.

La présente invention concerne une batterie. Un premier collecteur de courant dans la batterie est en contact avec une coque de batterie, de telle sorte que de la chaleur générée par un élément puisse être directement conduite vers la coque de batterie par l'intermédiaire du premier collecteur de courant. Un coefficient de conductivité thermique d'un collecteur de courant est très important, de telle sorte que les performances de dissipation de chaleur d'un élément soient améliorées. La batterie comprend : une coque de batterie, un premier collecteur de courant, un diaphragme et un second collecteur de courant, le premier collecteur de courant, le diaphragme et le second collecteur de courant étant empilés et agencés à l'intérieur de la coque de batterie, le premier collecteur de courant et le second collecteur de courant étant de polarité différente, et le premier collecteur de courant étant en contact avec la coque de batterie.
