LiNiVO{sub 4} is one of the most promising cathode materials due to its high cell voltage of 4.8 V. In this study, LiNiVO{sub 4} was prepared by the sol gel method. LiCH{sub 3}COO.2H{sub 2}O, Ni(CH{sub 3}COO){sub 2}.4H{sub 2}O and NH{sub 4}VO{sub 3} were used as the staring reactants. The total weight loss was 69.07% from the TGA result which agrees with the reaction mechanism proposed in this work. The product was successfully obtained at 750 deg. C for 5 h by sintering process. XRD studies for the treated sample confirms the formation of highly crystalline LiNiVO{sub 4}.
