A northern California lithium-ion battery company has devised an electric vehicle (EV) battery that reaches a full charge in just over ten minutes.  From ExtremeTech

In Brief

  • Silicon Anode (current iteration is graphite anodes)
  • Batteries to last 10 years


Enovix’s specialty is a silicon-anode lithium-ion battery it calls 3D Silicon. The name refers to a proprietary 3D architecture and constraint system, as well as the cells’ 100 percent active silicon anode. Enovix has previously used this technology to create batteries for smartphones, laptops, smart watches, and mobile radios. Its latest development, however, is a super fast-charging EV battery that will put even the Lucid Air to shame.

The company has demonstrated its 0.27 Ah test cells to be capable of charging from 0 to 80 percent “in as little as 5.2 minutes,” according to a press release. They’re able to reach 98 percent capacity within 10 minutes. Enovix conducted the tests as part of a three-year Department of Energy grant program challenging the company to create high-capacity, fast-charging EV batteries—an achievement it seems so far to have met. Even after 1,000 charge cycles (some under particularly high temperatures), the 3D Silicon batteries retained 93 percent of their capacity. Enovix therefore estimates its batteries will last at least 10 years.
