Military equipment intended for long duration use has a need for a basic long life primary battery that will exceed the 5-year life of current cells. This will lower the maintenance costs of devices such as remote sensors and electronics containing CMOS that require constant power. Johnson Research proposes the application of an all solid-state battery to meet the challenges of long battery life. Solid-state batteries do not suffer chemical degradations common in battery chemistries containing liquid components. Johnson Research’s sister company Excellatron has been producing thin film solid-state rechargeable batteries for a number of years and is poised to utilize LiPON solid electrolyte with a very low current leakage, which is required for the long duration battery. The proposed battery will meet and exceed all Army requirements of a 20-year primary battery for military application.
