Amprius to Integrate Safe Cells into Next-Generation U.S. Army Wearable Battery Pack
FREMONT, Calif. – Amprius Technologies, Inc. (“Amprius” or the “Company”) (NYSE: AMPX), a leader in next-generation lithium-ion batteries with its Silicon Anode Platform, today announced it will supply its state-of-the-art SiMaxx™ safe cells to complete the development and qualification for the U.S. Army’s next-generation Wearable Battery pack.
“Our SiMaxx™ safe cells, known for their high energy density and safety features, will play a crucial role in enhancing mission time and reliability for dismounted soldiers.”
One of the recent U.S. Army demands has been for wearable battery technology – powerful solutions in relatively lightweight and compact packages that soldiers can safely carry and wear. The U.S. Army has been working to revolutionize power solutions for dismounted soldiers by introducing a next-generation battery pack with significantly higher energy density than current solutions. When integrated into a battery pack, the SiMaxx™ safe cells will approximately double the energy density of existing solutions, significantly extending mission time for soldiers on the battlefield.
“This battery pack integration marks a significant advancement in enhancing on-the-ground power solutions for the U.S. Army,” said Dr. Kang Sun, CEO of Amprius Technologies. “Our SiMaxx™ safe cells, known for their high energy density and safety features, will play a crucial role in enhancing mission time and reliability for dismounted soldiers.”
This development in battery technology for the U.S. Army represents a substantial progression in wearable battery technology and underscores the importance of innovation in supporting the modernization efforts for our soldiers in the field.
The SiMaxx™ safe cells were developed as part of the U.S. Army-funded Manufacturing Technology (ManTech) program, an industrial preparedness effort focused on scaling critical Army-wide manufacturing requirements. In July 2023, Amprius SiMaxx™ safe cells successfully passed the rigorous safety and performance requirements of MIL-PRE-32383 (Military Performance Specification). In January 2024, Amprius successfully completed its scale-up manufacturing initiative under ManTech, which included the delivery of SiMaxx™ safe cells.
