Lithium-metal batteries are an important technology of 2021
Lithium-metal batteries have every chance to change the balance of power in the car market. Their energy density is equal to 1 kWh per liter of volume, which is almost twice as much as that of lithium-ion batteries. According to the MIT Technology Review, thanks to this, electric cars charge much faster, and most importantly, the charge lasts 80% longer than with lithium — ion batteries. Such indicators remain even after 800 cycles.
The American startup QuantumScape (Bill Gates is among its investors), which is developing lithium — metal batteries, conducted the first tests in December 2020. After successful tests, he has already signed a deal with Volkswagen, which will start producing electric cars with these batteries in 2025. Skeptics claim that the test results are too early to be considered successful: they were carried out on single-layer cells, whereas in real batteries they should be multilayer. In mass production, this can lead to unforeseen risks.
