Synthesis and characterization of Limn(2-x)Fex04 cathodic nano material for advanced lithiumion batteries / Aida Fazliza Mat Fadzi

New lithium transition metal oxides, LiMii(2-X)Fex04 where 0 < x <_0.5 are first synthesized using the sol-gel method. Stoichiometric samples are prepared. Thermogravimetric analysis ( TGA ) are carried out on the precursors to study the thermal properties and decomposition of the samples. The...
