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

Menghang Wang, Jingxuan Ding, Grace Xiong +8

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