American Enovix announced a traction battery that can be charged to 98% in less than 10 minutes

The charging time of traction batteries is crucial for the ubiquity of electric vehicles. American startup Enovix claims to be the market leader in new ultra-fast charging technologies and offers a solution that enables a near-full battery charge in less than 10 minutes.

There are already some fast charging technologies on the market. Many companies are involved in the development, from startups like StoreDot to large automakers like Volvo. For example, ABB announced “the fastest charger in the world‘, which can charge the vehicle’s traction batteries in less than 15 minutes. Enovix broke that record by developing its own “3D architecture of battery cells” for electric vehicles with silicon cathodes and anodes.

Silicon is often considered by designers as an alternative to graphite in battery solutions, believed to have the potential to provide higher energy intensity for traction batteries. Enovix, whose research is funded by a US Department of Energy grant, doesn’t go into specific numbers and says the company’s solution increases energy storage density for a given volume compared to competing options. According to the information available, the startup’s batteries can withstand more than 1,000 charge cycles while maintaining a capacity of 93%.

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.

The fast-charging capability could lead to mass adoption of electric vehicles, said CEO Harrold Rust, and the startup itself has demonstrated levels of performance that exceed many OEMs’ current expectations. According to him, car manufacturers are looking for large-capacity batteries, and infrastructure projects should increase the number of fast charging stations. The company has the potential to address both issues simultaneously by offering long-range batteries that charge in a very short time.
