摘要: The reaction mechanism and kinetics of formation LiNiO 2 using the particulate sol-gel (PSG) process derived precursors have been investigated a combination X-ray diffraction thermogravimetric analysis (TGA). It has confirmed that Li CO 3 NiO are intermediate products formed after decomposition xerogel. Subsequent heat-treatment initiates further between to form . A single peak observed in differential weight loss profile suggests direct with simultaneous evolution activation energy associated this is estimated as 98.5 kJ/mol nonisothermal Kissinger's method. reasons for faster PSG xerogel compared generated conventional solid-state also TGA transmission electron microscopy. Results studies facilitated synthesis nearly stoichiometric <2% anti-site defects.
