Lithium Ion Cell Aluminum Shell

Material for Power Battery Shell

Lithium battery shell design, round horn of square horn and two kinds of aluminum material for aluminum manganese alloy commonly, it contains the main alloy elements Mn, Cu, Mg, Si, Fe, etc., in the five kinds of alloy aluminum shell lithium-ion batteries plays a different role, such as Cu and Mg is to improve the strength and hardness, Mn to improve the corrosion resistance, Si can enhance effect of magnesium aluminum alloy heat treatment,Fe can improve high temperature strength.

Process for Battery Shell

Aluminum alloy raw materials --8 stations of continuous stretching molding -- rotary cutting head --9 steps of ultrasonic cleaning (oil and dirt removal) -- drying (60-70℃ drying for 40 minutes) -- inspection -- packaging -- shipment

Test for Lithium Cell Aluminum Shell

High pressure nitrogen equipment is used to test the pressure strength, requiring the pressure strength of 0.8mpa without air leakage, and the conventional pressure test strength of 1MPa.

1, The density of Aluminum Battery Case is 1/3 of steel, lightweight space is large;

2, Thermal conductivity is 5 times of steel;

3, Energy absorption per unit weight is twice that of steel;

4, Good extension performance;

5, Strong plasticity, good weldability, good production;

6, Casting performance is good, can be processed into different shapes;

7, This aluminum battery box is corrosion resistance, easy to recycle and regeneration

Lithium battery aluminum alloy shell is widely used in electric bicycles, electric vehicles, hydraulic, thermal, wind and solar power stations and other energy storage power system, as well as power tools, electric bicycles, electric motorcycles, electric vehicles, military equipment, aerospace and other fields.
