Low-grade thermal energy is abundantly available in industry, power plant, combustion engines and also solar and geothermal heat. However, it is still a great challenge to convert low grade heat into electric energy in an efficient way. Thermal charging and cycle on electrochemical system are newly proposed as an attractive method for efficient temperature thermal-electrical energy conversion. Here we applied a four-step thermal electrochemical cycle to commercial supercapacitor. Molecular dynamic simulation was performed on supercapacitor in different temperature and electrostatic potential. The structure of tetraethylammoinum tetrafluoroborate in acetonitrile electrolyte near graphene electrode was investigated to explore temperature effect on electrostatic cell potential, which explains how heat boosting ions moved, and further distributed to achieve a thermo-electrochemical cycle.
