The charging time of traction batteries is critical to the ubiquity of electric vehicles. Startup Enovix claims to be the market leader in new ultra-fast charging technologies, offering a solution capable of fully charging batteries in less than 15 minutes.

Fast charging technology already exists on the market. Many companies are involved in the development, from startups like StoreDot to large automakers like Volvo. Enovix broke the record by developing its own "3D battery cell architecture" for electric vehicles with silicon cathodes and anodes.

Silicon is often considered by developers as an alternative to graphite in battery solutions, potentially it can provide a higher energy content of traction batteries. Enovix, whose research is funded by a grant from the U.S. Department of Energy, won't go into specific numbers, saying the company's solution increases energy storage density at a given volume compared to competitive options. According to available information, the batteries are able to withstand more than 1000 charge cycles while maintaining 93% capacity.

The company expects that the development will be useful not only for electric vehicles, but also for energy storage for various purposes. On Monday, the company demonstrated the ability to charge a battery from 0 to 80% in 5.2 minutes and to 98% in less than 10 minutes.

According to company CEO Harold Rust, the fast-charging capability could lead to the mass adoption of electric vehicles, and the startup itself has shown a level of performance that exceeds the current expectations of many OEMs. In his opinion, automakers are looking for batteries with a large capacity, and infrastructure projects intend to increase the number of fast charging stations. The company has the potential to address both issues at the same time by offering long-range batteries that charge in a very short time.
