Abstract
ABSTRACT I − /I 3 − ‐based thermocells show great potential for low‐grade heat harvesting because of their affordability, adjustable electrochemical Seebeck coefficient ( S e ), and ease of device integration. However, current strategies of developing high‐performance I − /I 3 − ‐based thermocells usually result in substantial imbalance between S e and ultimate output power due to deteriorated ion transportation and replenishment. Herein, we propose a novel fluoride‐mediated coordination strategy to break this trade‐off. By introducing potassium fluoride and 1‐(2‐hydroxyethyl)imidazole (HEI) into the electrolyte, we engineer in situ formation of thermosensitive HEI‐I 2 F − coordinated complexes. These…
