Thermally regenerative electrochemical cycle
A battery is charged at one temperature and discharged at another; because its open-circuit voltage depends on temperature, the cycle nets electrical work from heat. A Carnot-like engine made of electrodes.

Relations
- a battery chemistry whose open-circuit voltage changes with temperature by ≈ 1 mV/K
- charge at one temperature, discharge at the other, with heat recuperation between the two
Matrix context
D = disequilibrium row · C = coupling family column. A cell reads the state of the atlas for that pair.
