Description Glycine-assisted sol-gel–synthesized multiple-doped spinels, LiM0.25Ni0.25Mn1.5O4 M = Cr, Fe, and Co have been studied as 5 V cathode materials. The sol-gel technique provides homogeneity, high purity, lower processing temperature, controlled particle size, and morphology. The synthesized samples were subjected to physical characterization studies, viz., thermogravimetric and differential thermal analysis, X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy, and electrochemical charge–discharge studies. Galvanostatic charge–discharge studies of the samples reveal that LiFe0.25Ni0.25Mn1.5O4 using glycine as a chelating agent delivers a stable capacity of 120 mAh g−1 even after 20 cycles when cycled between 3 and 5 V.
