Al2O3包覆正极材料LiNi1/3Co1/3Mn1/3O2
Al2O3-coated cathode material LiNi1/3CO1/3Mn1/3O2
摘要
Abstract
Cathode material LiNi1/3Co1/3Mn1/3O2 was synthesized by high temperature solid method and coated with aluminium oxide(Al2O3).The crystal structure,morphology of material were analyzed by XRD,SEM,the electrochemical performance of material was tested by galvanostatic charge/discharge and cyclic voltammetry.The cathode material LiNi1/3Co1/3Mn1/3O2 coated with Al2O3 had the typical structure of hexagonal α-NaFeO2 type,which belonged to the R-3m space group.The electrochemical performance of the material was best when the mass fraction of Al2O3 coating was 1％.When cycled in 2.5 ～ 4.3 V with 0.2 C,its initial specific discharge capacity reached up to 145.7 mAh/g,the capacity retention was 94.0％ after 30 cycles,the specific discharge capacity was improved by 6.3％ compared with the bare sample in the same condition.关键词
