The effect of nickel precursors on the electrochemical properties of spinel LiMn2-xNixO4 cathode: a comparative study ofNi(NO3)2·6H2O and NiSO4·6H2O as nickel sources

Author: Kunjuzwa, Niki ; Kebede, Mesfin A ; Mathe, Mahlanyane K ; Modibedi, Remegia M Date: May 2019 A comparative study was carried out with the effect of nickel precursors on the electrochemical performance of spinel LiMn2−x Ni x O4 (x = 0, 0.1 and 0.2) cathode materials. The spinel materials were prepared by employing a low temperature ... Read more
Stable nickel-substituted spinel cathode material (LiMn1.9Ni0.1O4) for lithium-ion batteries obtained by using a low temperature aqueous reduction technique

Author: Kunjuzwa, Niki ; Kebede, Mesfin A ; Ozoemena, Kenneth I ; Mathe, Mahlanyane K Date: Nov 2016 A nickel substituted spinel cathode material (LiMn1.9Ni0.1O4) with enhanced electrochemical performance was successfully synthesized by using a locally-sourced, low-cost manganese precursor, electrolytic manganese dioxide (EMD), and NiSO4·6H2O ...
