摘要: Abstract A particulate sol–gel (PSG) process has been developed for synthesizing LiNiO 2 and LiNi 0.75 Co 0.25 O powders. The is a modified derivative of the colloidal technique yields precursor that transforms to oxide by heat treatment at maximum temperature 800°C in only h. synthesized oxides also display good electrochemical activity (135 mA h/g 182 ) application lithium-ion rechargeable batteries. Detailed structural characterization as-prepared xerogels have conducted using Fourier transform infrared spectroscopy (FTIR), while studying their phase evolution behavior during X-ray diffraction (XRD). Results these studies described this work.
