American Startup Develops New Lithium-Ion Battery with Fast Charging and Long Lifespan, Retaining 93% Capacity After 1,000 Charge-Discharge Cycles.
When it comes to electric vehicles, people often focus on the driving range after each charge and the time required to fully charge the battery. American startup Enovix has developed a new battery that addresses the concern of charging time. On June 13, Enovix announced that its experimental 0.27 Ah battery cells for electric vehicles can charge from 0% to 80% in just 5.2 minutes and reach over 98% in less than 10 minutes.

Short charging times could accelerate the adoption of electric vehicles, according to Harrold Rust, co-founder and CEO of Enovix.
“Electric vehicle manufacturers are aiming for batteries that support longer ranges. Meanwhile, both public and private sectors are working to make it easier for electric vehicle drivers to access fast chargers. We are proud to support these goals to help electrify the automotive industry and demonstrate that our batteries are an exciting option for equipping electric vehicles with fast charging and long-range capabilities,” Rust said.
“The unique structure we have developed not only allows the battery to charge in under 10 minutes but also provides a high lifespan in terms of charge-discharge cycles,” said Ashok Lahiri, co-founder of Enovix.
According to Enovix, the company’s battery cells surpass 1,000 cycles while retaining 93% of their capacity. Testing also shows that after six months at high temperatures, Enovix batteries only experience a slight reduction in capacity. This indicates that the battery’s lifespan could exceed 10 years.
Enovix’s silicon lithium-ion batteries feature a proprietary 3D structure. The battery cells have silicon anodes, which theoretically can store lithium amounts twice as much as the graphite anodes used in most lithium-ion batteries. The 3D cell structure of Enovix also helps increase energy density and maintain a long lifespan.
Enovix is advancing its technology through a funding program from the U.S. Department of Energy. The company hopes to provide an efficient solution not only for electric vehicles but also for other energy storage purposes.
