This review provides deeper insights into building more comprehensive and efficient sodium metal anodes. The use of 3D conductive framework technology can significantly improve the cycle life and safety of sodium metal battery. The application of multi-strategy joint research methods will facilitate the practical process of sodium metal battery. Further exploration of the deposition behavior of sodium metal is required in the future. We believe that sodium metal will surely achieve commercial applications under continuous efforts.
