LiMn1.8Ni0.2O4 nanorods obtained from a novel route using α-MnOOH precursor as cathode material for lithium-ion batteries

Abstract

Nanorod structures of LiMn1.8Ni0.2O4 applicable as active cathode material for Li-ion batteries were synthesized from α-MnOOH and α-MnO2 initial phases. The LiMn1.8Ni0.2O4 spinel nanorods obtained from α-MnOOH using a novel, eco-friendly method showed higher purity than the traditional spinel obtained from α-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.
