Series of lithium manganese titanium spinel-like oxides LiMn2-yTiyO4 (0.2y1.5) were synthesized by solid state reaction carried out at 1100 deg C, followed by slow cooling to a particular temperature, depending on the titanium content y, and then air-quenched to room temperature. The procedure has p...
