摘要
Abstract
Using LiOH · H2O as the Li-source,LiNi0.6Co0.2Mn0.2O2 cathode was synthesized via high-temperature solid-state method.The influence of the synthesis temperature on the micro-morphology and Li-intercalation behavior of the product was investigated.The phase composition and microstructure were analyzed via XRD and SEM.The crystalline structure was α-NaFeO2type and no impurity was detected.The sample synthesized at 800 ℃ exhibited the best electrochemical performance.In the range of 3.0-4.3 V,the initial discharge capacity was 172 mAh/g,when the discharge current was set up at 28 mA/g.The discharge capacity was 159.4 mAh/g at the 100th cycle.关键词
