Amprius Technologies, Inc. (NYSE: AMPX) is a leading company in advanced lithium-ion batteries. They use a technology called the Silicon Anode Platform. Today, Amprius announced they have shipped SiMaxxTM A-Sample EV Cells. These cells went to the United States Advanced Battery Consortium LLC (USABC). The USABC’s mission is to develop advanced battery technologies. They want to improve the performance and reduce the cost of electric vehicle batteries.
These new cells aim to solve tough problems faced by electric vehicle users. Two main issues are range anxiety and long charging times. Range anxiety means feeling nervous that your electric car will lose power before reaching a charging station. Electric vehicles, or EVs, use electricity stored in batteries to run. If the battery gets low and there is nowhere to charge it, the car may stop working. This concern is called range anxiety. These new cells help by improving distance range and enabling faster charging.
90 % Charging in 15 minutes
Amprius’ own internal testing of the A-Sample Electric Vehicle Battery has shown exceptional performance, achieving a specific energy of 360 Wh/kg at the beginning of life—surpassing the USABC program target of 275 Wh/kg at end of life—while delivering a power density of 1200 W/kg. This breakthrough could result in a significant increase in range compared to most commercial EV batteries available today. Additionally, the A-Sample EV cells can charge to 90% of their rated energy in just 15 minutes, exceeding the USABC target of 80% within the same timeframe. Based on initial results, Amprius believes it is making significant strides towards achieving its goal of 1000 cycles.
USABC Validation of Electric Vehicle Battery
“We are eager to see the USABC validate the A-sample cell performance,” said Dr. Kang Sun. He is the CEO of Amprius Technologies.
The validation will show the unique benefits of Amprius cells in electric vehicles. These batteries are also used in aviation and light vehicle markets.
A silicon anode is a key part of a battery. It stores energy. Silicon anodes can hold more energy than typical materials. This makes them very useful for high-performance batteries.
With their superior energy and power performance, fast charging, wide operating temperature range, and safety features, Amprius is continuing to transform the electric vehicle battery and other electric mobility segments as we scale toward high-volume manufacturing.
Amprius has held technical engagements with multiple automotive OEMs and has had a long-standing collaboration with USABC. Delivered on schedule in September, the A-Sample EV cells shipment is the final milestone in the $3M USABC technology development contract awarded to Amprius in May 2022 to create a low-cost, fast-charge silicon nanowire battery. Amprius believes this achievement paves the way for additional sampling and evaluation by automotive manufacturers.
USABC is a subsidiary of the United States Council for Automotive Research LLC (USCAR), the collaborative technology company of Ford Motor Company, General Motors, and Stellantis. Enabled by a cooperative agreement with the U.S. Department of Energy (DOE), USABC’s mission is to develop electrochemical energy storage technologies that advance commercialization of next generation electrified vehicle applications. Supporting its mission, USABC has developed mid- and long-term goals to guide its projects and measure its progress.
