Description
Summary:Lithium-ion batteries (LIBs) have garnered significant academic and industrial focus because of their excellent merits, like high voltage, high energy density, excellent cyclic performance, no memory effect and environment-friendly nature. So far, the electrochemical properties of LIBs are restricted by the capacity of cathode materials and various novel compositions and designed architectures have been proposed to enhance the energy density and cyclic performance of LIBs cathodes. Recently, lithium nickel cobalt manganese oxides have attracted extensive research interest owing to the united advantages of LiCoO2, LiNiO2 and LiMnO2. Herein, we have reviewed the recent developments of LiNi1/3Co1/3Mn1/3O2 from the viewpoint of synthesis processes and structural designs. The electrochemical properties of LiNi1/3Co1/3Mn1/3O2 depend on particle size, morphology, ion doping and surface coating of the as-prepared cathode powder. The present article summarizes the recent developments and provides an insight into the future roadmap for the realization of high energy density LIBs. •Main synthesis methods of NCM cathodes are summarized and analyzed.•Partial ionic substitution enhances the structural stability and electronic conductivity.•Surface coating can prevent the side reactions, improved the electronic and ion migration rate.•Composite structure can increase the structure constancy and the electronic conductivity.
