Abstract

The invention relates to a lithium ion battery for an automobile. At present, no lithium ion battery with reasonable structural design and stable performance for the automobile exists. The lithium ion battery comprises a battery core, an upper cover, an anode terminal, a cathode terminal and a shell, and is characterized by further comprising an anode conductive metal plate, a cathode conductive metal plate, an anode cover plate, a cathode cover plate, a temperature detection guard plate and a metal isolation groove, wherein the anode terminal comprises an anode terminal body, an anode boss and an anode temperature measuring head; the anode conductive metal plate is fixed on the battery core anode plug of the battery core; the anode terminal body is fixed on the anode conductive metal plate; the cathode terminal comprises a cathode terminal body, a cathode boss and a cathode temperature measuring head; tThe cathode conductive metal plate is fixed on the battery core cathode lug of the battery core; the cathode terminal body is fixed on the cathode conductive metal plate; the wall faces of the shell are provided with multiple rows of heat-dissipating holes; and the inner walls of the wall faces, provided with the heat-dissipating holes, of the shell are provided with multiple heat-conducting grooves. The lithium ion battery for the automobile has the advantages of reasonable structural design, good heat dissipation and stable performance.

Description

technical field [0001] The invention relates to a lithium-ion battery, in particular to a lithium-ion battery for automobiles, which is specially used in electric vehicles to provide energy for the electric vehicles. Background technique [0002] At present, the structure design of the commonly used automotive lithium-ion battery is not reasonable enough, the performance is not reliable enough, the material consumption is large, and the production cost is high. There is a cell installation cavity in the battery shell, and the upper cover is directly fixed on the shell. The structural design of the shell is not reasonable enough, and the heat dissipation performance is poor. When the car battery is in use, the discharge current is large, the temperature generated is high, and a large amount of heat is difficult to dissipate, which greatly affects the overall performance of the car lithium-ion battery and shortens the life of the car battery. Ion battery life. [0003] The cu...
