Thermally induced capacitive effect of a nanoporous monel

As temperature changes, the equilibrium condition at a solid-liquid interface would be disrupted and the ion density varies, which, in turn, affects the interface potential. In the current study, this phenomenon is analyzed by using nanoporous monel electrodes. The experimental data show that, as the ion density is thermally adjusted, the capacitive effect leads to a significant thermal-to-electric energy conversion.
