Recent trends in thermoelectrochemical cells and thermally regenerative batteries

Given the ever-growing awareness on global warming, much interest has focused new and effective ways to manage energy, especially by harvesting exploiting low-temperature heat sources, ubiquitous in modern environment. Here, holy grail is direct conversion of into electricity using thermoelectric devices, this contribution, we focus thermoelectrochemical systems. We give a brief overview most common thermally regenerative electrochemical cells developed nowadays with short their thermodynamic derivation, collect some recent results terms properties, particular, temperature coefficients. see that although used redox couples are based Fe3+/Fe2+ derivates, thermodiffusion effects other entropy-related phenomena attracting attention scientific community boosting astonishing results. On hand, batteries emerging, showing modest performance.
