چکیده انگلیسی
The nickel–manganese compounds were synthesized by redox reactions in aqueous solutions using potassium permanganate and nickel chloride at ambient temperature. Layered structured materials in Li–Ni–Mn–O system were synthesized by using the formed nickel–manganese compounds as a precursor for electrode materials to examine the electrochemical activity. X-ray diffraction patterns of the Li2MnO3-like Li1.296Ni0.056Mn0.648O2 sample were indexed to a layered structure based on hexagonal α-NaFeO2 with a superlattice existence indicating a monoclinic Li2MnO3 crystalline phase. The electrode provides the initial discharge capacity of 108 mAh/g and the maximum discharge capacity of 192 mAh/g between 2.0 and 4.8 V versus Li/Li+ at 0.2 mA/cm2.
