Structural, electrical and electrochemical studies of copper substituted layered LiNi1/3Co1/3Mn1/3O2 cathode materials

open access: yesSouth African Journal of Chemical Engineering, 2019
The copper substituted in LiNi1/3Co1/3Mn1/3O2 cathode materials are synthesized by the solid state reaction method. Here, we are presenting the details of synthesized LiNi1/3Co(1/3-x)Mn1/3CuxO2 (0, 0.05, 0.1 and 0.15) as an alternative cathode material ...
