An all-round solution
The battery is one of the most important factors for the carbon footprint of all-electric vehicles. For this reason, the BMW Group Battery Cell Competence Centre in Munich is developing new, more sustainable generations of batteries with higher power density. Round-format battery cells are going to be used for the first time in BMW’s NEUE KLASSE models. “The sixth generation of our lithium-ion cells will enhance range by up to 30 % and improve charging speed by up to 30 %,” says Frank Weber, member of the Board of Management of BMW AG responsible for development.
CO2 emissions from the production of these batteries are expected to be reduced by up to 60 % compared with the previous generation. To achieve this, the BMW Group requires its partners in cell manufacturing to use green electricity and to reduce their consumption of primary raw materials. This means lithium, nickel and cobalt are partially used from secondary material that does not need to be newly mined. Any additionally required cobalt and lithium come from certified mines to guarantee responsible extraction. Furthermore, the Company requires members of its entire supply chain to adhere to strict environmental and social standards.
