Description

A key design feature affecting the performance and reliability of TDACS is the on-board energy storage system. Current systems utilize thermal batteries to meet their on-board energy storage needs. However, current thermal batteries have several notable limitations that can negatively impact mission assurance. Most notable are their relatively low energy density, their manufacturing complexity, and their performance reliability. Further, conventional thermal batteries require activation via the firing of an explosive squib, the reliability of which is of common concern. In response to the need for TDACS energy storage systems with increased performance and reliability as compared to thermal batteries, Solid Power proposes to continue efforts in Phase I towards the development of an all solid-state battery that possesses substantially high specific energy, low self-discharge, rechargeability and form-factor flexibility. Further, unlike conventional thermal batteries Solid Powers solid-state rechargeable batteries do not require activation thereby reducing system complexity (i.e., cost) and improving system reliability. Thus if successful, the proposed solid-state battery would result in lower cost, higher performing and increased reliability of the TDACS energy storage system.
