Unveiling the mechanism of redox ions for enhanced continuous discharge and output power in ionic thermoelectric materials
Hailong Sun, Jie Song, Peng Luo, Zhiliang Wan, Yi Niu, Muzhi Li, Tinghe Niu, Xinrui He, Chao Wang, Jing JiangBreaking the “synergistic superposition” paradigm, redox ions boost thermopower by tuning host ion diffusion disparity. Fe 2+ /Fe 3+ ions inhibit DCA − diffusion, thereby enhancing the cation–anion concentration gradient.
