Combustion synthesis of inverse spinel LiNiVO4 nano-particles using gelatine as the new fuel

An inverse spinel type LiNiVO4 nano-particles have been synthesized to be used as cathode active material for Li-ion batteries by adopting combustion method using gelatine as the new fuel, which act as an excellent combustion fuel as well as very good dispersing agent. The optimum temperature for the phase formation and/or complete crystallization of the precursor sample is found out by TG/DTA analysis. The structural property of the synthesized product is characterized by X-ray diffraction and FTIR spectroscopy studies. The morphology and the particle size of the synthesized powder is analyzed by TEM studies. The electrochemical reversibility and the charge/discharge studies of the synthesized LiNiVO4 are examined by fabricating lithium-ion polymer cell in the configuration of C/LiNiVO4 employing Li+ ion conducting PVdF-HFP based micro-porous polymer electrolyte.
