The new energy power battery shells on the market are mainly square in shape, usually made of 3003 aluminum alloy using hot rolled deep drawing process. Depending on the design requirements of the power battery, the thickness and width can be customized.
Aluminum alloy is a commonly used material for power batteries, and there is an urgent need to focus on research, development, and upgrading of products and alloy materials. At present, the conventional aluminum alloys used in power batteries mainly include 1-series, 3-series, 5-series, and 6-series.
If this ‘virtual battery’ system is applied to all three TRIMET plants in Germany then the storage capacity energy availability of the grid could increase by 7700 MWh, nearly as much as the largest German pump storage power plant. Almost 40% of this could be achieved solely by installation at Essen.
Chalco's production of power battery aluminum trays mostly uses 6-series 6061 aluminum plate as the raw material for battery aluminum trays, which can meet the characteristics of high precision, corrosion resistance, high temperature resistance, and impact resistance to protect the battery core.
Battery pack shell: the external shell used to secure and protect the battery module. The parts that may use aluminum alloy materials include power battery casing wall panels, brackets, etc. Connector: a component used to connect battery modules and other components.
The positive electrode ear of lithium-ion batteries uses 1050 or 1060 aluminum electrode ears, with a conductivity of 369000 S/cm, which can effectively improve the rate discharge performance of the battery. The specific specifications and parameters are as follows:
