DOIAbstract
In this work, NCM cathode materials, for Li-ion batteries, weresynthesized via a solid-state reaction routine, in which manganese(IV) dioxide, nickel (II) oxide, cobalt (II) hydroxide and lithiumhydroxide monohydrate were employed as metal precursors withdifferent calcination temperature. The prepared materials wereused as a cathode material for lithium-ion batteries and theelectrochemical performance was studied by galvanostatic chargedischargecycling, cyclic voltammetry, electrochemical impedancespectroscopy and rate capability, in which as electrolyte, 1M and1.5M LiPF6 in a mixture of ethylene carbonate and dimethylcarbonate (EC:DMC- 1:1 w/w and 1:2 w/w, respectively) wereemployed.Fil: Ortiz, Mariela Gisela.
