Lithium-ion battery capable of being easily disassembled and assembled

Abstract

The invention discloses a lithium-ion battery capable of being easily disassembled and assembled. The lithium-ion battery comprises a battery group consisting of at least two electric core bodies, and also comprises at least two first adapter boards and at least one second adapter board, wherein all the first adapter boards are respectively connected onto all the electric core bodies; each first adapter board comprises a first substrate, wherein the first substrate is provided with a first conducting convex body and a second conducting convex body in an embedding manner; the bottoms of the first conducting convex body and the second conducting convex body are also respectively and fixedly connected with a first nickle strip and a second nickle strip which are respectively and fixedly connected with a first tab and a second tab; each second adapter board comprises a second substrate; a circuit line is arranged in each second substrate; each second adapter board is detachably fixed on the end part of the battery group in a covering manner; and when each second adapter board covers the end part of the battery, the first conducting convex bodies and the second conducting convex bodies of all the first adapter boards are embedded into groove positions in the back surface of the at least one second adapter and are respectively contacted with conducting parts in all the groove positions.

Description

technical field [0001] The invention relates to the field of lithium ion batteries, in particular to an easily disassembled lithium ion battery. Background technique [0002] Due to its environmental protection and energy-saving characteristics, lithium-ion batteries have become the most widely used power source at present. Lithium-ion battery packs composed of multiple single batteries in series or parallel or series-parallel are due to their large capacity and high rate discharge characteristics. It has been more and more widely used as a power source to provide energy in various fields. [0003] In the prior art, when a plurality of cell groups are connected in series and parallel to form a lithium-ion battery pack, it is necessary to connect nickel strips to the lugs of each cell body, and then connect them according to the current series-parallel structure of the battery pack. The nickel strips are respectively welded to the adapter plate provided with the circuit boar...

AI Technical Summary

Problems solved by technology

[0005]It is difficult to disassemble the assembled lithium-ion battery pack, and in the prior art, when connecting the battery cores in series and parallel, welding is performed at least twice, and disassembly At this time, it is necessary to solder and melt each virtual nickel strip. The temperature of the soldering iron is as high as 380°C. Working on the tabs for a long time will easily lead to bad phenomena such as loose skin, flatulence, and softness of the battery core.
