摘要: Abstract Nano-sized HT-LiCoO 2 powders were prepared by sonochemical synthesis in an aqueous solution of lithium hydroxide containing cobalt at ∼80 °C without any further heat treatment high temperature. The effects the LiOH concentration, oxidation conditions, ultrasound irradiation time and temperature on formation nano-sized phase investigated. was confirmed X-ray diffraction Raman spectroscopy. TEM images showed presence aggregates with a mean particle diameter ∼20 nm. reaction mechanism assisted LiCoO proposed basis XRD, absorption spectroscopy analysis observation products taken during course synthesis.
