Abstract: The effect of treatment temperature on the specific surface area, morphology, particle size and metal content of spherical Ni0.65Co0.10Mn0.25(OH)2 precursors were systematically studied. X-ray diffraction, thermogravimetric, X-ray photoelectron spectroscopy were used to reveal the phase evolution behavior, thermal stability of the precursor and the valence state change of transition metal elements during high temperature treatment. |
Keywords: nickel-cobalt-manganese hydroxide co-precipitation specific surface area |
