The superior energy d. renders hybrid Li-air batteries (HLABs) promising candidate energy storage systems to enhance the sustainability of power grids. Nevertheless, HLABs operated at ambient temperature struggle to meet power and cycle life performance requirements for com. application. At the same time, low-grade heat is abundantly available from industrial processes as well as from solar-thermal or geothermal sources, but there is a blatant lack of technologies to efficiently convert low-grade waste heat into valuable elec. energy. We find that cells operated with an anolyte of tetraethylene glycol di-Me ether and 1 M aqueous lithium hydroxide as the catholyte achieve a marked decrease in cell polarization with an increasing operation temperature of up to 80°C. Therefore, the energy efficiency, η, can be increased significantly. While the increase from ηRT = 90% at room temperature to η353K = 98% efficiency at a reference c.d. 0.03 mA cm-2 may appear gradual, the increase in efficiency becomes rapidly more prominent with increasing c.d. (e.g., from ηRT = 59% to η353K = 84% at 0.5 mA cm-2). The addnl. elec. energy that can be drawn from a HLAB heated by low-grade waste heat leads to a highly attractive heat-to-power conversion efficiency. Enhancing the round-trip efficiency of grid-scale Li-air batteries opens a path to convert low-grade waste heat into valuable elec. energy.
