Abstract

The invention relates to the field of lithium-ion batteries, and discloses a novel lithium-ion battery pack and a preparation method thereof. The mechanism comprises an insulating shell, wherein a first lug groove and a second lug groove are arranged in the bottom of the insulating shell; a first sliding block and a second sliding block which are opposite to each on the front and the back are also arranged in the insulating shell; the back surfaces of the first sliding block and the second sliding block are connected with the inner wall of the shell by springs respectively; the first sliding block and the second sliding block can slide to be close to each other or far away from each other; a valve capable of being opened and closed is arranged at the top of the insulating shell; a space between the first sliding block and the second sliding block is filled with conductive bead bodies; and when the space between the first sliding block and the second sliding block is filled with the conductive bead bodies, any adjacent conductive bead bodies are in tight contact. By adopting the novel lithium-ion battery pack, maintenance, disassembly and assembly of the lithium-ion battery pack are facilitated.

Description

technical field [0001] The invention relates to the field of lithium-ion battery manufacturing, in particular to a lithium-ion battery pack, an assembly method and a tab connection mechanism. Background technique [0002] At present, there are roughly two ways to connect tabs in battery factories: soldering and ultrasonic welding. Once these two welding methods are connected, it is difficult to separate the tabs for repair. Contents of the invention [0003] One of the objectives of the embodiments of the present invention is to provide a lithium-ion battery pack, an assembly method, and a lug connection mechanism. Adopting this technical solution is beneficial to the maintenance and disassembly of the lithium-ion battery pack. [0004] In the first aspect, a lithium-ion battery pack provided by an embodiment of the present invention includes at least two lithium-ion battery cells connected to each other. There is a connecting mechanism, [0005] The connection mechanism...
