Abstract

Thermocells (also called thermo-electrochemical cells) are a promising technology for converting low-grade heat (<200°C) into electricity through temperature-dependent redox reactions and/or ion diffusion. Very recently, there have been several breakthroughs in thermocells regarding Seebeck coefficients up to 34 mVK–1 and efficiencies up to 11% by optimizing thermo-electrochemical processes. Proof-of-concept devices can obtain a power output on the order of 100 mW by harvesting ambient body heat or solar energy, which are effective power sources for various electronic devices. The rapid pace of advances in this field, however, also trigger rigorous controversies, including volatility, low power density, and the degradation of redox couples. Herein, we provide a holistic discussion on the current-state knowledge for improving thermocell performance and examine a few state-of-the-art engineering strategies for broadening the application of thermocells.
