The utilization of waste heat produced in industrial processes or geothermal activity is an attractive approach for relieving some of our present reliance on fossil fuels. Devices that allow the direct conversion of thermal energy to electrical energy, with a flexible design and no carbon emissions, have the potential for widespread use.
Our work with ionic liquid-based thermoelectrochemical devices offers the possibility of cheap and flexible device design suitable for harvesting waste heat in the 100-200°C range. The use of ionic liquid electrolytes, which can have negligible volatility and good thermal and electrochemical stability, will eliminate any problem of evaporation from the device with long-term use. It also increases the temperatures that can be harvested compared to traditional aqueous-based devices.
Our group has made remarkable progress in this area and has recently demonstrated the highest reported Seebeck coefficients and power outputs to-date for ionic liquid-based thermoelectrochemical cells by using a high entropy change cobalt redox couple.
