US Patent 11961988 Hybrid battery system comprising a continuous power source

A semiconductor-based battery system comprising a primary battery that spontaneously provides power that in embodiments trickle-charges a secondary battery. The battery obtains power as heat from the surrounding environment. The primary battery is powered through internal blackbody radiation, which cools a micro-platform and provides thermoelectric power at all temperatures above absolute zero with available power increasing with temperature. Lifetime of the primary battery is not limited by electrochemical degradation over time. In embodiments, the primary battery powers an application device directly without a secondary battery.
