Objective
Thermal batteries are devices that convert thermal energy without the need for a spatial temperature gradient, giving them anenormous potential advantage over competing methods. Despite its promise, thermal batteries are yet not suitable for practicalapplication as they were demonstrated only with liquid electrolytes, which severely restricts the operation temperature range toΔT<50 K and an electrochemical stability window to pair with thermodynamically efficient electrodes. The goal is to develop acompletely new paradigm towards all-solid-state thermal battery (thermal cell), which is based on reversible changes of the materials’electrochemical properties and on H+ transport operating on recovered waste heat over an unusual wide range of temperatures ofambient to 300°C. We envision the solid thermal battery to charge at a defined low and high constant temperature due to phasechanges and H+ intercalation taking place at the electrodes. Fundamentally, we contribute to a new thermal battery concept, suggestmaterials to translate the proposed chemistry-at-work and give a proof-of-concept to gain first electrochemical performance insightsdefining thin film device architectures. Collectively, the here proposed solid thermal battery closes the ever-existing gap betweenthermoelectric and liquid based thermal batteries through widening of the thermal operation window to capture waste heat anddefining a new set of H+ solid conductors and interfaces suited for energy storage. The fundamentals derived on electrochemicalinterfaces and H+ conductor films such as ceria-based, metal hydride, binary oxide and possibly high entropy alloys for electrolytesand electrodes contribute in their design and careful discussion of electro-thermo-chemistry, thermodynamics and kinetics toengineering design principles of the here proposed fully solid thermal batteries for energy harvesting putting waste heat to workwith perspective for industry translation.
