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 batteries do not compete with nonaqueous batteries in energy density; the salient advantage of proton storage is its rate capability, which is associated with its tiny size and its nature of forming hydrogen bonding. The recent progress on Grotthuss proton storage is the high rate performance.
Proton, as a charge carrier, is most attractive due to its size and the associated advantages. Recently, reversible proton insertion in electrodes has emerged in electrochemical energy storage. Unlike the conventional understanding on pseudocapacitive proton storage, more focus is allocated to the topotactic structural changes.
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.
In addition, the proton insertion process places the electrode material at a more negative potential, as shown schematically in Fig. 3c,d, leading to an increase in the energy of the electrons.

Un protón es una partícula subatómica con carga eléctrica positiva que se encuentra dentro del núcleo atómico de los átomos.El número de protones en el núcleo atómico es el que determina el número atómico de un elemento que se indica en la tabla periódica de los elementos.. El protón no es una partícula elemental sino una partícula compuesta.
