Eutectic solvent as electrolytes for rechargeable proton batteries

Key Points

Proton batteries using eutectic electrolytes achieve a reversible capacity of 116 mA h g after 50 cycles, a significant improvement.
These electrolytes, formed by HTFSA and MTFAA, effectively suppress the dissolution of TiO<sub>x</sub> in acidic environments.
Observational analysis demonstrated the stability of hydrogen-bonded liquids used as nonflammable electrolytes.
This technology may enable safer and more efficient rechargeable proton batteries in future applications.

Abstract

In this work, we developed eutectic electrolytes composed of HTFSA and MTFAA, which form stable hydrogen-bonded liquids functioning as nonflammable proton battery electrolytes. They effectively suppress the dissolution of TiOx that readily dissolves in acidic aqueous media, delivering a reversible capacity of 116 mA h g-1 after 50 cycles.
