Solvent-free protic liquid enabling batteries operation at an ultra-wide temperature range

M. Liao, X. Ji, et al.

Explore the groundbreaking research by Mochou Liao and colleagues as they unveil polyphosphoric acid (PPA) as a revolutionary solvent-free protic liquid electrolyte for batteries. PPA promises nonflammability, a wide electrochemical stability window, and stable performance at extreme temperatures. Their innovative approach, using a MoO3/LiVPO4F battery, demonstrates exceptional power density at elevated temperatures, paving the way for safer and more reliable battery technologies.
