Sulfur-based thermally regenerative cascade batteries enabling dual electrochemical reactions for enhanced power generation
A thermally regenerative cascade battery (TRCB) coupling a Cu<sub>2</sub>S/S redox process with a Cu<sup>2+</sup>/Cu redox reaction is proposed. The Cu<sub>2</sub>S participates in energy conversion and promotes the Cu<sup>2+</sup>/Cu redox reaction, achieving a power density of 14.2 mW cm<sup>-2</sup>. Adjusting the Cu-to-S ratio is proven to provide tunable electrode capacity and boost power generation.
