"Stable sodium metal anodes enabled by an in-situ generated mixed-ion/e" by Xiaolong Zhu, Yan Wang et al.
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 CuP2 into the mixed conductor of Cu and Na3P, enable dendrite-free Na plating/stripping in ether-ba...
