Lithium battery cell with good heat dissipation effect and protection function

Abstract

The invention discloses a lithium battery cell with a good heat dissipation effect and a protection function in the technical field of lithium batteries. A cell body is arranged in an inner cavity ofa cell shell, a front baffle is arranged on the left side wall of the cell shell, a rear baffle is arranged on the right side wall of the cell shell, and two heat dissipation fans are installed on theinner wall of the front baffle. A heat dissipation aluminum plate is inserted between the cell bodies, the liquid cooling pipes are arranged on the surfaces of the two ends of the cell bodies and attached to the surfaces of the two ends of the cell bodies, buffer strips are embedded in the surface of the damping shell in a sliding mode, elastic buffer blocks are arranged on the side walls of thebuffer strips at equal intervals, two buffer columns are symmetrically arranged on the side walls of the other faces of the buffer strips, the buffer column is inserted to the cavity of a damping sleeve, and the other end of a damping spring is fixedly connected with the inner wall of thedamping sleeve. The advantages that the heat dissipation effect is good, the lithium battery cell can be protected, and the service life of the lithium battery cell is prolonged can be achieved.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a lithium battery cell with good heat dissipation effect and protection function. Background technique [0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. The cell refers to a single electrochemical cell containing positive and negative electrodes, which is generally not used directly. The difference is that the battery contains a protective circuit and a casing and can be used directly. [0003] When the lithium battery cell is working, it will generate high heat. If it is not dissipated in time, it may cause damage to the components inside it. Moreover, the existing lithium battery cells do not have protection functions, and the components may be damaged due to impact. The damage will increase the cost of use. For this reason, we propose a lithium batt...

[0003] When the lithium battery cell is working, it will generate high heat. If it is not dissipated in time, it may cause damage to the components inside it. Moreover, the existing lithium battery cells do not have protection functions, and the components may be damaged due to impact. The damage will increase the cost of use. For this reason, we propose a lithium battery cell with good heat dissipation effect and protective function.
