It is technologically very complicated to make lithium-ion batteries for electric cars, but constant progress has enabled us to produce increasingly efficient batteries at the same compact size.

Batteries are the most crucial part of any electric car and are designed to last for the entire life of the vehicle.

After a battery has served its time in an electric car, it can be either recycled or repurposed, for example, for home or industrial energy storage. This second-life application can significantly extend the battery's overall useful life before it is eventually recycled.

High-voltage traction batteries from electric cars can already be recycled very efficiently. The vast majority of valuable materials can be recovered and then reused in electrical equipment.
