Abstract

The invention provides a square lithium battery which comprises a shell assembly and a battery cell arranged in the shell assembly, the battery is characterized in that the shell assembly comprises a first shell, a second shell, a positive electrode cover plate, a negative electrode cover plate and a barrier strip; one end of the first shell is clamped at the top of the positive electrode cover plate, and the other end of the first shell is clamped at the top of the negative electrode cover plate; one end of the second shell is clamped at the bottom of the positive electrode cover plate, and the other end of the second shell is clamped at the bottom of the negative electrode cover plate; and the first shell and the second shell abut against each other. The positive electrode cover plate is connected with a positive electrode lug of the battery cell; the negative electrode cover plate is connected with a negative electrode lug of the battery cell; the positive electrode cover plate and the negative electrode cover plate have the same structure; and one end of the barrier strip is connected with the positive electrode cover plate, and the other end of the barrier strip is connected with the negative electrode cover plate. The problems that the longitudinal length of the lithium battery shell is too long and the assembly is difficult can be solved, and the battery core can enter the shell and an electrolyte solution can be injected conveniently.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a square lithium battery. 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. Lithium batteries have the characteristics of light weight, large energy storage, no pollution and long service life. Therefore, lithium batteries are widely used in various industries. [0003] At present, the shell of the square lithium battery on the market is usually composed of a cover plate and an aluminum shell. This design makes the positive and negative poles of the lithium battery on the same side, resulting in an increase in the temperature rise of the tabs of the lithium battery during operation. Large, poor heat dissipation, affecting the performance of lithium batteries, especially for high-rate batteries. In order to prevent heat from affectin...
