      abstract     = {High capacity sodium (Na) metal anodes open up new
                      opportunities for developing next-generation rechargeable
                      batteries with both high power and high energy densities.
                      However, many challenges still plagued their practical
                      application, including low plating/stripping Coulombic
                      efficiency (CE) and dendrite growth after repeated cycle
                      inducing safety issue. Especially, the sodium metal is less
                      stable in organic (i.e. carbonate-based) electrolytes than
                      lithium metal, due to the more unstable organic
                      solid–electrolyte interface (SEI). Herein, we report a
                      facile technology to stabilize sodium metal anode and
                      inhibit the growth of sodium dendrites. The in-situ
                      ultrathin NaI SEI layer successfully endows best-performance
                      Na/I2 metal batteries (>2200 cycles) with high capacity (210
                      mA h g−1 at 0.5 C) based on the conversion reaction
                      chemistry with higher discharge voltage plateau (> 2.7 V)
                      and lower overpotential (134 mV) due to the fast charge
                      transfer dynamics and interfacial stability compared with
                      pristine Na anode. The detailed theoretical calculations and
                      experimental results elucidate that NaI layer has a much
                      lower diffusion barrier compared to that of NaF (NaF as one
                      the most commonly found inorganic components in Na-based SEI
                      layer), and actually facilitates more uniform sodium
                      deposition. This work provides a new avenue for designing
                      low-cost, high-performance and high-safety sodium
                      metal-iodine batteries and other metal-iodine batteries.},
