Problems solved by technology

However, the lithium battery has severe heat generation during use. When the heat dissipation effect of the lithium battery shell is not ideal, the internal air pressure of the lithium battery is prone to rise. When the internal air pressure exceeds the critical point of explosion, the battery will explode, causing casualties.

Abstract

The invention discloses a lithium battery structure capable of rapidly dissipating heat. The lithium ion battery comprises a battery cell and a cover cap. The cover cap is connected with the battery cell through a tab; the battery cell is annular; a first annular protective layer is attached to the inner side wall of the battery cell; a first annular heat dissipation layer is formed on the inner side of the first annular protective layer; a first annular heat dissipation cavity is formed between the first annular protective layer and the first annular heat dissipation layer in a sealed mode; an axis heat dissipation cavity is formed in the inner side of the first annular heat dissipation layer; a second annular protective layer is attached to the outer side wall of the battery cell; a second annular heat dissipation layer is formed on the outer side of the second annular protective layer; a second annular heat dissipation cavity is formed between the second annular protective layer andthe second annular heat dissipation layer in a sealed mode; and the first annular heat dissipation cavity and the second annular heat dissipation cavity are filled with cooling liquid respectively. According to the invention, the battery cell is arranged to be annular, and the protective layers, the heat dissipation cavities and the heat dissipation layers are additionally arranged on the annularinner side, so that the heat dissipation effect is better than that of an original technical scheme.

Description

technical field [0001] The present application relates to lithium batteries, in particular to a lithium battery structure with rapid heat dissipation. Background technique [0002] Lithium-ion secondary battery (referred to as lithium battery) has the characteristics of small size, light weight, high working voltage, high energy, long cycle life and low pollution. It is an ideal energy source for future development and has been applied in more and more fields. However, the lithium battery has severe heat generation during use. When the heat dissipation effect of the lithium battery shell is not ideal, the internal air pressure of the lithium battery is prone to rise. When the internal air pressure exceeds the critical point of explosion, the battery will explode, causing casualties. . Therefore, it is necessary to consider the heat dissipation of the lithium battery during use. [0003] Patent No. CN201820691687.1 discloses a rapid heat dissipation lithium battery, which c...
