Characterization of Inverse Spinel LiNiVO_4 Cathode Materials Prepared by the Sol-gel and Polymer Precursor Method

摘要

1 Results Due to the high cell voltage of LiNiVO4,the compound properties have been continuously studied as the potential cathode material for Li-ion batteries.LiNiVO4 cathode product has been known to exhibit high cell voltage of 4.8 V[1].LiCH3COO.2H2O (Sigma),Ni(CH3COO)2.4H2O (Aldrich) and NH4VO3(Ajax Finechem) were used as the starting reactants. In this work,LiNiVO4 was prepared by the sol gel method.This method was used to replace the conventional solid state reaction method in terms of the sample ...
