Amprius Technologies, a technology leader in the development of next-generation Li-Ion batteries, is once again raising the bar in lithium-ion cell technology with its innovative silicon anode platform. These batteries currently provide an excellent energy density of 500 Wh/kg or 1300 Wh/l.
This technology breaks down current technical barriers.

Thanks to these values, the new batteries guarantee unrivaled runtimes. Among the significant features of the new batteries are the speed of charging (up to 80% of capacity in less than 6 minutes), safety under difficult conditions (successful completion of special military tests), and operability over a wide temperature range (-30°C to 55°C). As reported by Next Big Future, at approximately half the weight and volume of the most advanced commercially available Li-Ion cells, the new battery cell delivers unprecedented performance, breaking previously unknown technical boundaries.
Next-generation cells are well positioned for use in the fast-growing aerospace markets and, of course, in electric cars, where demand is expected to exceed $100 billion by 2025.

The new platform is tailored especially for applications that require maximum endurance while maintaining key parameters required for operation. The system allows customers the choice of either increasing the amount of energy in the battery pack without increasing the weight, or reducing the weight of the battery pack while maintaining the amount of energy required. The higher energy content benefits longer run time, range and endurance, while the lighter design increases energy efficiency for the same energy content.
For example, Pierre-Antoine Aubourg, technical director of AALTO HAPS, the Airbus subsidiary developing the Zephyr solar-electric aircraft, is looking forward to the new cells. It will be operated in the stratosphere and will serve both scientific and commercial purposes. Sandy Munro, a well-known engineer and tester, also shared information about the new battery cells on his YouTube channel.
