Research Progress on High‐Energy Rechargeable Sn‐Based Batteries

ABSTRACT Sn‐based batteries have emerged as an optimal energy storage system owing to their abundant Sn resources, environmental compatibility, non‐toxicity, corrosion resistance, and high hydrogen evolution overpotential. However, the practical application of these batteries is hindered by challenges such as “dead Sn” shedding and hydrogen evolution side reactions. Extensive research has focused on improving the performance of Sn‐based batteries. This paper provides a comprehensive review of the recent advancements in Sn‐based battery research, including the selection of current collectors, electrolyte optimization, and the development of new cathode materials. The energy storage mechanisms and challenges of Sn‐based batteries are discussed. Overall, this paper presents future perspectives of high‐performance rechargeable Sn‐based batteries and provides valuable guidance for developing Sn‐based energy storage technologies.
