Abstract

Abstract: The composite Li1.231 Mn0.615 Ni0.154 O2 has been prepared by a facile combustion synthesis. X‐ray diffraction, thermogravimetric analysis, chemical analysis, X‐ray photoelectron spectroscopy and scanning electron microscope were used to characterize the resultant composite and its precursor. The results show that a well‐crystallized layered hexagonal structured composite Li1.231 Mn IV 0.615 Ni II 0.154 O2 is obtained. The resultant composite serves as a cathode material for lithium ion batteries, and galvanostatic charge/discharge tests and cyclic voltammetry revealed that the composite exhibits excellent electrochemical performance. The as‐prepared electrode delivers an average specific energy density as high as 795 W h kg –1 in the range 4.8–2.0 V (vs. Li/Li + ) at a constant current density of 20 mA g –1 . Abstract : The cathode material Li1.231 Mn0.615 Ni0.154 O2 has been successfully synthesized by a facile combustion method. The final product exhibits good electrochemical performances.
