FREMONT, Calif. – Amprius Technologies, Inc., a leader in ultra-high energy density lithium-ion batteries with its Silicon Nanowire Anode Platform, today announced that it will host a demonstration on Wednesday, October 26, 2022, at 1:00 p.m. EDT, of one of its battery’s extreme fast charge rate of 0-80% state of charge in less than six minutes.

Amprius has been in commercial production since 2018 and has continued to evolve its batteries in pursuit of game-changing performance, offering batteries that provide superior performance compared to conventional graphite lithium-ion batteries.

During the virtual demonstration, Amprius’ Chief Technology Officer Dr. Ionel Stefan will explain the proprietary silicon nanowire anode technology and the unique battery characteristics that make it well-positioned to address the electric mobility market.

Dr. Stefan will be testing Amprius’ Aviation High Power Fast Charge Cell (P/N CL0007 Silicon Nanowire Anode / LCO Cathode) that has the following specifications:

  • 2.75Ah capacity
  • 28 g weight
  • 360 Wh/kg at C/5 discharge (Amprius provides range of batteries between 360-450 Wh/kg)
  • 890 Wh/L at C/5 discharge (Amprius provides range of batteries between 890-1,400 Wh/L)
  • Greater than 100 cycles to 80% of initial capacity at 100% DoD
  • Max continuous discharge current 12.5A (5C)

This technological advancement validates Amprius’ performance against the U.S. Advanced Battery Consortium 2025 goal of 0-80% in sub-15 minutes and has been verified by third-party independent testing.

Amprius’ Chief Executive Officer Dr. Kang Sun and Chief Operating Officer Jon Bornstein will join Dr. Stefan for a question-and-answer session following the extreme fast charge demonstration.
