American soldiers are about to get a major power boost thanks to a new deal between the US Army and Amprius Technologies, a California-based leader in next-generation batteries.

This collaboration, announced last Thursday (May 9), marks a significant leap forward in wearable battery technology, promising to extend mission times and enhance soldier capabilities on the battlefield.

SiMaxx Cells: Lightweight Powerhouses

The heart of the project lies in Amprius’ revolutionary SiMaxx battery cells.

These lightweight powerhouses boast an energy density of 400-500 watt-hours per kilogram, doubling the capacity of previous iterations.

This translates to soldiers carrying the same weight but getting twice the juice to power their critical equipment – a game-changer in terms of endurance and operational flexibility.

“This battery pack integration marks a significant advancement in enhancing on-the-ground power solutions for the US Army,” said Dr. Kang Sun, CEO of Amprius Technologies. “Our SiMaxx safe cells will play a crucial role in enhancing mission time and reliability for dismounted soldiers.”

Beyond extended runtime, the SiMaxx cells excel in charging speeds.

They can be recharged to 80 percent capacity in a mere 6 to 30 minutes, a critical feature for soldiers in fast-paced combat scenarios. This eliminates the need for bulky generators or reliance on fixed charging stations, allowing for greater mobility and adaptability.
