The invention has good electrical conductivity, convenient assembly and prevents displacement.

Description

technical field [0001] The invention relates to a lithium ion battery, in particular to a lithium ion battery for automobiles. Background technique [0002] At present, the design of the commonly used lithium-ion batteries for automobiles is not reasonable enough, the structure is not simple enough, and it is prone to short circuit between the positive and negative electrodes. In the same battery pack, it is easy to move between two adjacent lithium-ion batteries for automobiles In addition, the heat dissipation effect between two adjacent lithium-ion batteries for automobiles is poor, and there is no structure for positioning and support on the housing, which brings great inconvenience to the normal use of the battery pack. In addition, the existing casings are usually connected by ultrasonic waves during the assembly process. The workload of casing assembly is large, the tools used are complicated, and the assembly, maintenance and repair are inconvenient. The poles of ex...

[0002] At present, the design of the commonly used lithium-ion batteries for automobiles is not reasonable enough, the structure is not simple enough, and it is prone to short circuit between the positive and negative electrodes. In the same battery pack, it is easy to move between two adjacent lithium-ion batteries for automobiles In addition, the heat dissipation effect between two adjacent lithium-ion batteries for automobiles is poor, and there is no structure for positioning and support on the shell, which brings great inconvenience to the normal use of the battery pack.

In addition, the existing shells are usually connected by ultrasonic waves during the assembly process. The workload of the shell assembly is large, the tools used are complicated, the assembly is inconvenient, and the maintenance and repair are inconvenient.

The poles of existing automotive lithium-ion batteries are usually columnar structures, and the wires are generally fixed on the poles by welding. The contact area between the wires and the poles is small, and the electrical conductivity is poor; The requirements are high, which increases the workload and reduces the work efficiency; after the wire and the pole are welded, it is easy to have virtual welding and desoldering, the reliability of the connection is poor, and there are potential safety hazards

To sum up, there is currently no automotive lithium-ion battery with reasonable structural design, reliable connection, good electrical conductivity, convenient assembly, and effective prevention of displacement between two adjacent automotive lithium-ion batteries.
