Amprius has made significant advancements in EV battery technology
Nov 7, 2024
Amprius Technologies has made significant advancements in electric vehicle (EV) battery technology and has submitted its innovative SiMaxx A-sample EV cells, designed to address key EV market challenges such as range anxiety and the need for fast charging, to the U.S. Advanced Battery Consortium (USABC).
High Energy Density Exceeds Standards
Amprius’ A-sample EV cells demonstrated impressive results, surpassing several USABC targets. These cells provide an energy density of 360 Wh/kg, exceeding USABC’s ultimate target of 275 Wh/kg. This increase in efficiency enables electric vehicles to travel longer distances without increasing battery size.
Fast Charging Capability
Beyond energy density, these cells can charge to 90% in just 15 minutes, surpassing the USABC’s goal of 80% in the same timeframe. This fast-charging capability can greatly reduce range anxiety and enhance the convenience of EV ownership.
USABC’s Role in Battery Innovation
USABC is a division of the U.S. Automotive Research Council, collaborating with Ford, GM, and Stellantis. Supported by the Department of Energy (DOE), USABC’s mission is to advance energy storage technologies to accelerate the commercialization of next-generation EVs.
Amprius is working closely with USABC and the DOE to develop cutting-edge battery cells and is in discussions with numerous automakers to implement this technology. With over 500 MWh of manufacturing contracts in place, Amprius is prepared to scale production and deliver high-performance batteries to EV customers.
