Revealing the proton slingshot mechanism in solid acid electrolytes through machine learning molecular dynamics

Menghang Wang, Jingxuan Ding, Grace Xiong +8

In solid acid solid electrolytes CsH${}_2$PO${}_4$ and CsHSO${}_4$, mechanisms of fast proton conduction have long been debated and attributed to either local proton hopping or polyanion…
