Abstract
A Metal Hydride Solid Oxide Battery has been explored to answer the need for high energy density power required for High Altitude Long Endurance (HALE) aircraft. Lithium Hydride is a fuel source that can be stably stored for long periods allowing for a high level of readiness. Further, Lithium Hydride has a high energy density. The electrochemical oxidation of Lithium Hydride is far more effective than Carnot limited heat engines. When utilized in an electrochemical cell, energy densities of 1800Wh/kg and specific energy of more than 1100Wh/liter are anticipated. This cell can operate at high altitudes in thin air where many other energy alternatives are limited.
