Original Abstract

In this work, NCM cathode materials, for Li-ion batteries, were synthesized via a solid-state reaction routine, in which manganese (IV) dioxide, nickel (II) oxide, cobalt (II) hydroxide and lithium hydroxide monohydrate were employed as metal precursors with different calcination temperature. The prepared materials were used as a cathode material for lithium-ion batteries and the electrochemical performance was studied by galvanostatic chargedischarge cycling, cyclic voltammetry, electrochemical impedance spectroscopy and rate capability, in which as electrolyte, 1M and 1.5M LiPF6 in a mixture of ethylene carbonate and dimethyl carbonate (EC:DMC- 1:1 w/w and 1:2 w/w, respectively) were employed.
