Recent Progress and Perspectives of Sodium Metal Anodes for Rechargeable Batteries

Sodium metal anodes have attracted significant attention due to their high specific capacity, low redox potential and abundant resources. However, the dendrites and unstable solid electrolyte interphase(SEI) of sodium anodes restrict the development of sodium metal batteries. This review includes th...

Description
Summary:Sodium metal anodes have attracted significant attention due to their high specific capacity, low redox potential and abundant resources. However, the dendrites and unstable solid electrolyte interphase(SEI) of sodium anodes restrict the development of sodium metal batteries. This review includes the recent progress on the Na anode protection in sodium metal batteries. The strategies are summarized as modified three-dimensional current collectors, artificial solid electrolyte interphases, and electrolyte modifications. Conclusions and perspectives are envisaged for the further understanding and development of Na metal anodes.
