QuantumScape's solid-state battery is twice as good as comparable lithium-ion batteries

Representatives of the Californian company QuantumScape have issued a statement that their new solid-state lithium metal battery could be the first commercial version. after all, its efficiency turned out to be higher than similar lithium-ion batteries installed in electric cars, which gave 80% power reserve at a charging speed from full zero to 80% in 15 minutes.

What is special about the new solid state battery

The use of a solid electrolyte (instead of a classical liquid solution) allows one to accumulate a substantially larger amount of energy per unit mass.

But creating a solid-state battery that could withstand the harsh conditions in a car (fast charge / discharge, low and high temperatures) proved to be a daunting task.

But to engineers QuantumScape nevertheless, it was possible to solve a whole cascade of problems and create a fully functional battery.

So it was a decision to use, in addition to lithium-metal anodes, a solid-state separator, which was implemented from hard ceramic material, which proved to be able to strongly resist the formation of so-called dendrites.

For reference. Dendrites are one of the main problems that lead to a significant decrease in initial capacity The battery and in the event of a breakthrough of the separator lead to a closure of the cell, and in some cases even to fire.

In addition, the company's engineers managed to increase the energy density and now the new solid-state battery is capable of storing 1 kWh per one liter of volume, which is almost two times more than that of batteries used in electric cars Tesla model 3 (from 380 to 500 kWh per liter.

Plus, with incredibly fast charging from 0% before 80% In just 15 minutes after 800 charge-discharge cycles (corresponding to approximately 400,000 km), the solid-state battery retains 80% from its original capacity.

Also, the company's engineers emphasize that even at temperatures of -30 degrees Celsius, their new solid-state lithium-metal battery remains operational.

And at the same time, most of the declared volume is available. In addition, their battery is completely safe, since it was possible to realize the most reliable protection of the anode and cathode.

Well, if QuantumScape manages to bring its new solid-state battery to mass production, then this will be a significant breakthrough in the availability of electric vehicles around the world (including the northern regions).
