The thermoelectric power depends strongly on concentrations of both the ionic liquid and the redox couple. It is enhanced by a factor of six at high ionic-liquid concentrations. The control of these parameters can be used to enhance the thermopower and the thermoelectric efficiency of future ionic-liquid thermocells. %G English %L cea-01384313 %U https://cea.hal.science/cea-01384313 %~ IN2P3 %~ CEA %~ IPNO %~ CNRS %~ UNIV-PSUD %~ IRAMIS-SPEC %~ UNIV-PARIS-SACLAY %~ UNIV-PSUD-SACLAY %~ IRAMIS %~ GS-PHYSIQUE
