Cylindrical lithium battery assembly tool

Abstract

The present invention relates to a cylindrical lithium battery assembly tool. The cylindrical lithium battery assembly tool includes a lithium battery assembly module and two lithium battery connection modules. The two lithium battery connection modules are symmetrically installed at two ends of the lithium battery assembly module by using assembly screws, and each lithium battery connection module and the assembly screw are connected in a laser welding manner. The laser welding manner has high welding quality, and lowers a probability of faults such as short circuit and poor contact that occur after long time use of corresponding lithium battery. The lithium battery assembly module adopts a modular decentralized installation design, so that the lithium batteries can be installed rapidly no matter how many lithium batteries are assembled, and the lithium batteries are simple to assemble and disassemble; and a gap between any two adjacent lithium batteries is large, so that the heat dissipation effect is good. The lithium battery connection modules can be customized and processed according to a quantity of the lithium batteries that are assembled in a modular decentralized manner in the lithium battery assembly module, the lithium batteries can be connected once, and two lithium batteries do not need to be connected separately. Through adoption of the cylindrical lithium battery assembly tool, a modular disassembling function of a lithium battery pack can be realized.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a cylindrical lithium battery assembly tool. Background technique [0002] A lithium-ion battery is a battery that mainly uses carbon materials as the negative electrode, a lithium-containing compound as the positive electrode, and uses a non-aqueous electrolyte solution. With the continuous development of lithium-ion batteries, in order to meet the requirements of higher voltage and capacity, it is necessary to connect multiple lithium batteries in series to form a power lithium battery pack, which is widely used in battery cars, motorcycles, automobiles and other Power supply equipment and other fields. [0003] Most of the current lithium battery packs are basically composed of individual lithium batteries bundled together, and then connected in series and parallel by connecting piece welding. This method has the following disadvantages: 1. The gap between lithium b...
