Synthesis and characterization of Li–Mn–V–O spinel as cathode material for lithium battery applications

A low temperature sol-gel technique was employed for the synthesis of vanadium substituted spinel of the type LiMn2−xVxO4 (x = 0.1 to 0.5). X-ray diffraction data indicates evidence for substitution of vanadium in the lattice. Particle size, FTIR, and differential thermal analyses were carried out on the samples. Charge–discharge characteristics of cells fabricated using these materials were studied. The cells were found to be stable for more than 20 cycles.
