文摘

An amorphous lithium ion conductor layer was successfully deposited on LiNi0.6Co0.2Mn0.2O2 surface. The concentration of lithium residues on LiNi0.6Co0.2Mn0.2O2 surface was reduced. 1 mol% LLTO modified LiNi0.6Co0.2Mn0.2O2 exhibits excellent electrochemical performance. LLTO coating layer alleviates structure degradation and suppresses interfacial resistance increasing.
