主　　题：Na metal anode Solid electrolyte interphase Electrolyte Dendrite Na-metal batteries 

摘      要：Na metal anode, benefiting from its high theoretical capacity and lowest electrochemical potential, ~sone of the most favorable candidates for future Na-based batteries with high energy density. Dendritegrowth, volume change and high reactivity are the formidable challenges in terms of good cycling perfor-mance and high Coulombic efficiency as well as an expected safety guarantee of Na metal anode for thepractical application. Solid electrolyte interphase （SEI） layer as an indispensable component of a battery,its formation and stability play the critical role in the feasibility of Na metal anode. In this review, wefirst discuss the current consideration and challenges of Na metal anode, and then summarize severalstrategies to suppress dendrite growth and improve electrochemical performance, including interface en-gineering, electrolyte composition, electrode construction, and so on. Finally, the conclusion and futureperspective of potential development on Na metal anode are proposed.
