Description

The current state of the art thermal battery technologies will not be able to meet future requirements that call for higher power and capacity with a smaller footprint. The principal avenue for increasing the capacity of thermal battery is to identify and develop new electrode materials that provide higher specific capacity and power performance. The overall objective of the proposed effort is to develop (design, fabricate, test and demonstrate) novel cathode materials for thermal battery with high single cell potential (>2.5V), high energy density. In Phase I, we have utilized a judicious combination of experimentation and knowledge of thermal battery systems to establish proof-of-concept for the newly proposed cathode material. We have focused on the characterization and demonstration of the proposed thermal battery with novel cathodes through: (1) design and synthesis of cathode materials, (2) development of high voltage electrolytes, (3) fabrication of custom experimental testing cells, and (4) electrochemical testing and characterization of the proposed thermal battery. In Phase II we will extend upon this work with further characterization of the new materials along with scale-up and delivery of thermal batteries to the Army for independent evaluation.
