Great Breakthrough! Big News From Solid-state Battery, Energy Density 4 Times Model 3, Charging 80% In 15 Minutes!

Recently, the solid-state batteries used in electric vehicles have come out with big news.

Solid state battery breakthrough, charging 80% in 15 minutes

As the biggest bottleneck of electric vehicle, battery has always been the biggest factor to determine the performance of electric vehicle. The battery with high energy density and fast charging is the key to help the electric vehicle industry take off. Recently, the solid-state batteries used in electric vehicles are getting big news.

On December 8 local time, Quantum Scape, a start-up backed by Volkswagen and Bill Gates, released its latest stunning performance data for solid-state batteries. The data show that it can increase the range of electric vehicles by 80% and fill them up with 80% in 15 minutes (usually 40 minutes or more for lithium-ion batteries). The normal service life of a vehicle with a range of 300 miles or more will reach about 12 years. At the same time, tests showed that the battery did not deteriorate after 800 cycles, equivalent to 240000 miles (380000 km) of driving distance.

What surprised the industry was not only its excellent charging speed, but also its ultra-high energy density. The bulk energy density of the battery exceeds 1000 watt hours per liter, which is almost twice the density of the top commercial lithium-ion battery pack and four times that of the current Tesla Model 3 battery. By weight, it can provide 380 to 500 watt hours per kilogram, compared with about 260 watt hours per kilogram of energy currently available in Tesla batteries.
