Abstract
Nanorod structures of LiMn1.8Ni0.2O4 applicable as active cathode material for Li-ion batteries were synthesized from ?-MnOOH and ?-MnO2 initial phases. The LiMn1.8Ni0.2O4 spinel nanorods obtained from ?-MnOOH using a novel, eco-friendly method showed higher purity than the traditional spinel obtained from ?-MnO2. The showed charge capacity that was in the order of 122 mA h g?1 higher than similar active material reported in the literature, and it was able to keep >80% of initial capacity at a charge rate of 5 C.
