Material properties of Lithium battery aluminum cases
Automotive battery aluminum cases are mainly based on high-performance aluminum alloys, which have outstanding material advantages. Aluminum alloy has low density and light weight, which can significantly achieve lightweighting of battery systems; Simultaneously possessing excellent corrosion resistance, it can maintain structural stability in complex environments such as humidity and high temperature, and is not easily corroded by electrolytes and external media. In addition, aluminum also has good electrical and thermal conductivity, combined with suitable structural strength and formability, making it an ideal material for Aluminum cases for new energy cars.
Core functions of Lithium battery aluminum cases
New energy aluminum battery cases play multiple critical roles in battery operation.
Firstly, there is structural protection, which can tightly wrap the internal components such as battery cells, electrodes, and separators, isolate moisture, dust, and external foreign objects, and prevent internal components from being corroded and mechanically damaged.
Secondly, to enhance safety performance, relying on good thermal conductivity to quickly dissipate the working heat of the battery, reducing the risk of thermal runaway, while relying on its own strength and toughness to resist impact, compression, and vibration, reducing the hidden danger of battery damage.
Finally, optimizing the electrochemical performance, good conductivity helps to reduce battery internal resistance, improve energy density and charge discharge efficiency, and lightweight design further enhances the comprehensive utilization efficiency of Aluminum battery casing.
