Synthesis And Modification Of Lithium Nickel Oxides As Cathode Materials Of Lithium Ion Battery

LiNiO2-based compounds were promising candidates of cathode materials for lithium ion batteries. But they still possessed various problems such as the difficulty of preparation, the poor heat stability and the dissatisfactory cycleability performance and so on, which insolubility for its practical applications, so it must be optimized synthesis and changed perfomance. A study on the synthesis, structure and electrochemical performance of LiNiO2-based compounds as cathode materials for lithium ion batteries was carried out systemically and detailedly, by the research techniques of XRD, SEM, TG-DTA and the electrochemistry test, and simply construed the mechanism of doped Ti in this dissertation.In this work, layered LiNi1-xAlxO2(0
