Amprius Technologies has shipped SiMaxx A-Sample EV Cells to the United States Advanced Battery Consortium (USABC).
These cells are designed to overcome some of the most challenging issues experienced by EV users, including range anxiety and the need for shorter charging times.
While tackling these issues their mission remains to develop advanced battery cell and system technologies to meet next-generation performance and cost goals for electric vehicles.
The shipment of the A-Sample EV cells is the final milestone in the $3M USABC technology development contract awarded to Amprius in May 2022, to develop a fast-charge, low-cost silicon nanowire battery. The advanced battery design effectively enhances the capabilities of UAV, HAPS, LEV, EV, eVTOL, and unmanned ground vehicles.
Dr. Kang Sun, CEO of Amprius Technologies stated, “We look forward to USABC validation of the A-sample cell performance towards showcasing the unique advantages of Amprius cells in electric vehicles.”
“This is another important battery technology development milestone at Amprius after we successfully launched high-performance silicon anode battery business in aviation and light vehicle markets. We believe our batteries are well-positioned to support all electric mobility markets. With their superior energy and power performance, fast charging, wide operating temperature range, and safety features, Amprius is continuing to transform the EV sector and other electric mobility segments as we scale toward high-volume manufacturing.” Dr. Kang Sun concludes.
Internal testing of the A-Sample EV cell has shown exceptional performance results, achieving a specific energy of 360 Wh/kg at the beginning of life–the USABC program target of 275 Wh/kg at end of life being surpassed–while delivering a power density of 1200 W/kg. In addition, 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.
This milestone could result in a significant increase in range compared to most commercial EV batteries available today. Amprius believes its making significant strides towards achieving its goal of 1000 cycles, based on initial results.
