Low tensile strength and hardness of the aluminum shell of the power battery can lead to low compressive strength and hardness, and the profile is prone to curved and tortuous shapes. Impact on battery stability High-frequency Welded Long Cell Shell Battery Pack
The new energy long cell battery shell developed and produced by our company adopts a cold bending forming+high-frequency welding process, which breaks through the constraints of traditional deep drawing/extrusion processes and overcomes the welding technology of ultra-thin aluminum shells.
The new energy vehicle long cell battery shell sector, as the company’s main strategic development direction in the future, will become the main sector for the company’s transformation from the traditional automotive industry to the new energy vehicle industry.
In principle, two different forming methods are applicable for prismatic cell cases made of aluminum: deep draw or impact extrusion. Both methods are combined with wall ironing to come to the final geometry and reach the thin walls as specified and in tolerance.
Battery casings are essential components in all types of lithium and lithium-ion batteries (LIBs) and typically consist of nickel-coated steel hard casings for 18650 and 21700 cell formats. These steel casings comprise over one quarter of total battery cell mass and do not actively contribute to battery capacity.
These steel casings comprise over one quarter of total battery cell mass and do not actively contribute to battery capacity. It is therefore possible to achieve considerable battery performance improvements, in terms of device energy density, by reducing the mass of the battery casing.
