摘要：

The effects of different coating layers on lithium metal anode formed by reacting with different controlled atmospheres(argon,CO;–O;（2:1）,N;,and CO;–O;–N;（2:1:3）)have been investigated.The obtained XRD,second ion mass spectroscopy（SIMS）,and scanning probe microscope（SPM）results demonstrate the formation of coating layers composed of Li;CO;,Li;N,and the mixture of them on lithium tablets,respectively.The Li/Li symmetrical cell and Li/S cell are assembled to prove the advantages of the protected lithium tablet on electrochemical performance.The 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.
