Abstract

In this work, LiCoPO₄ nanoparticles were synthesized by supercritical fluid method using cobalt nitrate hexahydrate (Co(NO₃)₂ 6H₂O) and cobalt acetate tetrahydrate (C₄H₆CoO₄ 4H₂O) as starting materials. The effect of starting materials on particle morphology, size, and the crystalline phase were investigated. The as-synthesized samples were systematically characterized by XRD, TEM, STEM, EDS, BET, and TG and charge-discharge measurements. In addition, Rietveld refinement analysis was performed. The electrochemical measurements of LiCoPO₄ nanoparticles have shown differences in capacities depending on the starting materials used in the synthesis and the results have been discussed in this paper.
