To address the excessive consumption of fossil fuels, a tremendous development of clean and renewable energy sources is taking place in modern society, highlighting the significant position of electrochemical e. Benefiting from fast proton diffusion dynamics, aqueous metal-proton batteries (. As the demand for clean and renewable energy source increases, rechargeable batteries are indispensable for electrochemical energy storage,1, 2, 3, 4, 5, 6, 7, 8, 9 and in p. In AMPBs, cathode materials have a strong tendency to store protons, and this can be achieved by rational design of both the cathode and the electrolyte. Although a full understanding of. Organic compoundsThe typical proton-storage organic compounds usually contain carbonyl (C=O) and/or imino moiety (=N−) redox centers (Figure 2), and th. Although many types of materials can store protons, not all of them can be used as the cathode in AMPBs. First, the electrolyte should be compatible with the proton-storage materials.

What are the challenges for advancing proton batteries?
Developing high-performance proton electrodes and understanding their energy storage mechanisms have been considered as the main challenges for advancing proton batteries. Unlike research on alkaline metal-ion batteries where coin-cells are commonly adopted, there are no standardized devices for electrode evaluation in proton batteries.
Can proton batteries achieve high-performance aqueous energy storage?
Finally, the state-of-the-art proton full-cells are explored, and views on the rational design of proton battery devices for achieving high-performance aqueous energy storage are offered.
Are proton batteries a promising solution for grid-scale energy storage?
Abstract Proton batteries have emerged as a promising solution for grid-scale energy storage benefiting their high safety and abundant raw materials. The battery chemistry based on proton-ions is i...
How can aqueous proton batteries improve sustainability?
In terms of the synthesis of organic compounds, one direction is to improve sustainability by using low-toxicity and low-cost chemical agents as well as minimizing the reaction and purification steps. These will benefit the large-scale production of aqueous proton batteries.
Do proton batteries compete with nonaqueous batteries in energy density?
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.
Are aqueous metal-proton batteries suitable for high-performance energy storage devices?
Benefiting from fast proton diffusion dynamics, aqueous metal-proton batteries (AMPBs) comprising a proton-storage cathode and a metal anode serve as an emerging system with tremendous potential for high-power energy-storage devices. However, there have been few reports on how to systematically design and construct high-performance AMPBs.
