Effect of Various Fuel Conditions on the Synthesis of Nano Crystalline LiNiVO4 Powders - Material Science
LiNiVO4 is of interest as a potential cathode material for rechargeable (secondary) lithium ion battery applications. The use of LiNiVO4 instead of LiCoO2, LiMn2O4 or LiNiO2 offers a higher voltage of 4.8V in these batteries. Better performance of this cathode material is due to its physical and chemical properties like crystallite size, homogeneity, which are mainly depends on the synthesis
process and fuel conditions. Hence, in the present work, Nano crystalline inverse spinel LiNiVO4 powders were prepared by the gel combustion method with lithium, Nickel nitrides and ammonium Vanadate as oxidant and starch and glycine mixtures as fuels. Reaction conditions and behavior of the polymeric intermediates as well as crystal structure morphology of LiNiVO4 nanopowders were investigated by, FTIR, SEM and XRD methods. Results showed that pure LiNiVO4 nano powders was fabricated by gel combustion method and nano powders with 88nm crystallite size was obtained by using 1.04 Molar ratio of fuel to oxidant materials.
