Abstract

En 中文

Sodium (Na) metal is viewed as a promising anode material for advanced high-energy rechargeable batteries own to its high theoretical capacity, low electrochemical potential and abundant availability. Nevertheless, the unstable solid electrolyte interphase (SEI) results in low Coulombic efficiency, a limited cycling life, and dendrite-related issues. Therefore, constructing an excellent SEI is crucial for improving the performance of Na metal anodes through appropriate strategies. This review first discusses the challenges faced by Na metal anodes in practical applications. It then summarizes recent advancement in strategies for constructing stable SEIs, including electrolyte regulation, artificial SEI engineering and substrate modification strategies. Last, review presents the perspectives on future research aimed at the practical application of Na metal anodes in high-energy-density Na metal batteries.
