  • Publication number: 20250075293
    Abstract: A battery cell housing having an aluminium alloy strip or sheet. The object of providing a battery cell housing having an aluminium alloy strip or sheet which, on the one hand, makes it possible to achieve recycling rates and, on the other hand, satisfies the requirements of a battery cell housing, in particular with regard to strength, electrolyte stability and electrical and thermal conductivity, is achieved in that the aluminium alloy strip or sheet has an aluminium alloy with the following alloy constituents in wt %: 0.1%?Si?0.5%, 0.25%?Fe?0.8%, Cu?0.6%, 0.6%?Mn?1.4%, 0.5%?Fe?1.5%, Cr?0.25%, Zn?0.4%, 0.005%?Ti?0.2%, the remainder being Al and unavoidable impurities, individually at most 0.05% and in total at most 0.15%.

  • Publication number: 20240332679
    Abstract: A battery cell housing of a round battery cell includes a cylindrical housing shell with an outer diameter of more than 15 mm, preferably more than 20 mm, particularly preferably more than 22 mm, and to the use of an aluminium alloy for manufacturing a battery cell housing. The object of providing a high-strength battery cell housing of a round battery cell, having a cylindrical housing shell with a diameter of more than 15 mm, preferably more than 20 mm, in particular more than 22 mm, which allows improved properties regarding heat management and weight of the round battery cell without excessively limiting the capacity of the round battery cell, is achieved in that the housing shell consists at least partially of an aluminium alloy, and the yield strength Rp0.2 of the housing shell is at least 183 MPa, preferably at least 220 MPa, particularly preferably at least 250 MPa.
