- Recently metal oxides have been investigated as negative electrodes in Li-ion batteries. In this study, metal oxide nanoparticle was prepared using supercritical hydrothermal synthesis method that could be applied for mass production. Hydrothermal synthesis of metal oxide (MO, where M is Ni, Cu, or Co) nanoparticles from metal nitrate aqueous solution was carried out at 673 K and pressures 30 MPa with a flow-through supercritical water method. Size, phase and crystallinity of the obtained particles were characterized by SEM and XRD, respectively. The electrochemical properties of the as-synthesized metal oxide nanoparticles were investigated to determine their suitability as anode materials for lithium-ion batteries. The supercritical hydrothermal synthesis method might be a useful method to prepare metal oxide nanoparticle for the anode material of lithium batteries.
