Official Description

Electrically rechargeable batteries are of central importance for powering a wide range of military applications, including vehicles, computational assets, and sensing and communication devices. However, endurance is currently limited by the low-energy-density of state-of-the-art lithium-ion batteries (~400 Wh/kg). Recent advances in air-breathing battery and fuel cell chemistry have made it feasible to envision electrically rechargeable systems with specific energy many times that of lithium-io...
