The focus of the project is to obtain battery cells with a higher density energy, while also reducing production costs. BMW has already been optimizing battery cell technology and achieving bigger results with every new generation. The Gen5 battery, which was presented with the BMW iX3 in 2020, had a lower content of cobalt and a higher percentage of nickel. And recyclable nickel is a key component in reducing the use of primary resources, which leads to a “greener” battery.
And the German company isn’t stopping here. The goal is to increase the energy density of battery cells even more, until the end of this decade, when a solid-state battery will completely replace Li-ion batteries. Until then, BMW predicts they will unveil the first car to use this new technology as early as 2025.
"The greenest electric car in the world will be a BMW – sustainable from the initial idea to recycling after its use phase. We are developing the battery cell of the future: it will be powerful, safe, cost-effective, and recyclable - from material selection to recyclability after the use in the vehicle. All of this will be created in a European value chain.", says Frank Weber, Member of the Board of Management of BMW AG, Development.
The Group’s “electric offensive” is not showing any signs of slowing down. The BMW i4 and the BMW iX are set to join the previous three electric models that have already been launched, later this year. And fully-electric version of the BMW 5 Series and BMW X1 are on their way.
