In our latest paper in Joule by Zhang et al., we reported a charging-free thermally regenerative electrochemical cycles system with the aid of dual-mode thermal regulations for solar energy harvesting and radiative cooling, enabling efficient conversion of energy from two crucial sources on Earth: the sun with a temperature of around 6,000 K and outer space with a temperature of 3 K.
