Abstract
A proton battery is considered as a promising energy storage solution with the merits of fast kinetics, high safety, low cost, and environmental benignity. The realization of these merits depends on the exploration of the appropriate and high-performance electrode materials. Although many anode materials of proton batteries have been reported, a dedicated summary of the progress, challenges, and prospects of anode materials for proton batteries has not been reported. Through discussions on the proton storage mechanisms, advantages and limitations of various anode materials, optimization strategies to boost their proton storage capability, and their potential applications, this review seeks to provide a comprehensive theoretical foundation and practical guidance for future research and development of proton battery technology. First, the preparation methods and proton storage mechanism of anode materials have been discussed. Then, the limitations and optimization strategies have been summarized. After that, the next section elaborately focuses on the proton storage performance of different types of anode materials. Finally, the challenges and prospects of anode materials for proton batteries have been proposed. This review aims to provide insight into the efficient design and optimization of anode materials for practical applications of proton batteries.
