A new electric vehicle battery developed by California-based Amprius Technologies has a silicon anode and can reach 90 percent charge in 15 minutes.
The company sent its cell samples to the United States Advanced Battery Consortium (USABC), an organization of American car manufacturers established to improve battery technology, the report said.
Amprius Technology, which previously supplied fast-charging battery packs for the aerospace and light vehicle markets, is now moving into the electric vehicle sector. These cells can reach 80 percent charge in less than six minutes. The A cells supplied by Amprius have a high specific energy of 360 Wh/kg and a power density of 1200 W/kg. When they become commercially available, these cells will allow far greater ranges than current batteries offer, he says HAK magazine.
The firm is also working on achieving 1,000 charge cycles with its batteries. In addition to working in temperatures that vary – 30 degrees to 55 degrees, the battery has also passed the nail penetration test, demonstrating superior safety.
Amprius’ batteries use lithium-ion cells, the most energy-dense solution available today, but by a small margin. Instead of graphite on the anode, the company uses silicon, which provides 10x higher energy capacity and a much better life cycle.
Amprius has already secured 500 MWh of contracted production capacity to meet customer demand, the press release added.
