摘要：

Lithium nitride (Li3N) and stretchable polymer solid electrolyte which conduct Li ions and blocks electrons are synthesized and applied to fabricate self-healing artificial solid electrolyte interface layer aiming to solve the issue of electrochemical degradation in Li electrodes. An ingenious artificial solid electrolyte interface layer by in situ reaction of Cu3N with Li metal using Cu3N particles and solid electrolyte is designed. The artificial Li3N solid electrolyte interface (SEI) layer can restrain the unfavorable reaction between the Li metal and the electrolyte and Li dendrite growth can also be restrained in Lithium batteries. It is found that the Li3N layer exhibit exceptional abilities of promoting battery lifetime and stabilizing the cycling behavior after galvanostatic measurements are performed on both symmetric cells and Li/Li4Ti5O12 half cells.
