Redox potentials of various redox-active molecules were examined in highly concentrated electrolytes. At the high concentration regions, the shifts were significantly larger than the conventional trend («0.059 V/dec) expected from the salt concentration terms in the Nernst equation. Decreased activity of the molecular salts was considered to explain the shift. The dramatic potential changes will play essential roles in designing molecule-based energy devices.
