摘      要：The effects of different coating layers on lithium metal anode formed by reacting with different controlled atmospheres（argon,CO_2–O_2（2：1）,N_2,and CO_2–O_2–N_2（2：1：3））have been *** obtained XRD,second ion mass spectroscopy（SIMS）,and scanning probe microscope（SPM）results demonstrate the formation of coating layers composed of Li_2CO_3,Li_3N,and the mixture of them on lithium tablets,*** Li/Li symmetrical cell and Li/S cell are assembled to prove the advantages of the protected lithium tablet on electrochemical *** comparison of SEM and SIMS characterizations before/after cycles clarifies that an SEI-like composition formed on the lithium tablets could modulate the interfacial stabilization between the lithium foil and the ether electrolyte.
