Sodium metal has been regarded as one of excellent candidates of anode materials for the next-generation high-energy sodium-ion batteries owing to its low redox potential, low cost, and high theoretical capacity. However, the poor reversibility and the dendrite growth of Na anode on cycling have significantly hindered the practical application of sodium metal anodes (SMAs). Herein, we report that a mixed-ion/electron-conducting interface (MIECI) layer, in-situ generated through the conversion of...

Abstract Sodium metal anodes (SMAs) are regarded as a good candidate for next-generation alkali metal batteries owing to the higher natural reserves and lower cost of sodium. Nevertheless, the challenging issues associated with SMAs, including the dendritic formation and the high reactivity of sodium metal, have significantly impeded the utilization of SMAs in the practical deployment of sodium metal batteries. Herein, we report that 2D graphitic carbon frameworks embedded with highly dispersiv...
