We have synthesized LiNi0.5−xMn1.5−xM2xO4 (M=Al, Cr) materials by polyvinyl alcohol (PVA) method, and investigated the effect of the synthetic condition on the electrochemical performance including charge-discharge cycling tests. The characterization of the materials obtained was performed by X-ray diffraction, BET measurement, chemical analysis, and galvanostatic electrochemical measurements. It was found that all synthesized LiNi0.5−xMn1.5−xM2xO4 (M=Al, Cr) materials consist of LiNi0.5Mn1.5O4 phase including a small amount of impurity NiO phase. Al and Cr substituted LiNi0.45Mn1.45M0.10O4 (M=Al, Cr) samples showed better C-rate performance, e.g., with a main discharge plateau of ∼4.7 V, and the discharge capacity of ∼100 mAh (g-oxide)−1 at a 10C rate and 25°C, compared to LiNi0.5Mn1.5O4.
