Tests on Enovix Corporation’s next generation 3D Silicon™ lithium-ion battery shows it can charge in around five minutes in electric vehicle application.
The California, US firm has demonstrated its 0.27Ah EV test-cells charged from 0-80% state-of-charge in 5.2 minutes and achieved a greater than 98% charge capacity in under 10 minutes.
Harrold Rust, co-founder, CEO and president of Enovix said the battery technology could help accelerate mass adoption of EVs.
He said: “We’ve been able to demonstrate a level of performance that meets and exceeds many OEM roadmaps.
“EV manufacturers are in pursuit of batteries that support longer range, while the public and private sectors work to increase EV driver access to fast chargers.”
As part of the company’s three-year Department of Energy grant program that is pairing a 100% active silicon anode with EV-class battery cathode materials, the company’s cells surpassed 1,000 cycles while retaining 93% of their capacity.
Testing also demonstrated that after six months at elevated temperatures, the batteries had minimal capacity loss; this pairing is projecting a calendar life of greater than 10 years.
