Abstract. Merited by its fast proton diffusion kinetics, proton batteries are qualified as one of the most next-generation energy storage devices. The recent emergence and explosive development of various proton batteries requires us to re-examine the relationship between protons and electrode materials.
Proton battery consists of electrolyte and corresponding proton storage host material (cathode/anode). Acidic electrolytes are usually considered as proton donors, such as H 2 SO 4, HCl, and H 3 PO 4, etc. It is worth noting that protons are often ignored in mild electrolytes. Multivalent ions such as Al 3+ and Zn 2+ will react with solvent
