Enovix, based in Fremont, California, announced that it demonstrated in electric vehicle (EV) battery cells the ability to charge from 0% to 80% state-of-charge in as little as 5.2 minutes and to achieve a greater than 98% charge capacity in under 10 minutes. The cells also surpassed 1,000 cycles while retaining 93% of their capacity.
The achievement shattered the United States Advanced Battery Consortium (USABC) goal of achieving 80% charge in 15 minutes.
Other goals for USABC at the cell level include a usable energy density of 550 Wh/L, a survival temperature range of -40 to +66 degrees C, and a cost of $75/kWh at an annual output volume of 250,000 units. A full set of USABC targets can be found here.
The company demonstrated the fast-charge ability in its 0.27 Ah EV cells in its silicon lithium-ion batteries, which it said contain a novel 3D architecture and constraint system. The cells contain a 100% active silicon anode. Enovix said the material has long been heralded as an important technology in the next generation of battery anodes.

Electric vehicle battery capable of 98% charge in less than ten minutes
Enovix also demonstrated its US-made silicon anode lithium-ion batteries can charge 0% to 80% in five minutes.
