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

Autor: Jorge A. Calderón, Jorge Enrique Thomas, Arnaldo Visintin, Ferley A. Vásquez

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 sh
