Colloidal Synthesis of NiO Nanocrystals and Application on Lithium-ion Battery Anode |
| 초록 |
Recently, the internal combustion engines (ICE) are denounced since they have produced greenhouse gas, for instance carbon dioxide, which is detrimental to the environment. Therefore, electrical vehicles (EVs), hybrid electrical vehicles (HEVs) and plug-in electrical vehicles (PEVs) are gathering interest of executive researchers either the public since they utilize electricity rather than fossil fuels. Lithium-ion batteries (LIBs) are one of the promising candidates for EVs due to their high energy and power density. To date, graphite has been used to anode material of the LIB because of its feasibility, stability, high rate and cycle performance at low temperature. However, since it has intrinsic limited interstitial site for lithium-ion storage, there have been a lot of demand for the material that possesses property of large energy density. Nano-sized nickel monoxide (NiO) has been widely studied due to their multiple Li storage nature on the interstitial site which enables higher specific capacity (over 600 mAh g-1) than the commercial graphite (over 300 mAh g-1). But to the best of our knowledge, the NiO prepared by colloidal synthetic method and its electrochemical behavior on LIB have not been reported yet. Herein we report the NiO nanoparticles synthesized in colloidal phase and detailed electrochemical analyses through several analytical instruments. We expect that the nano-sized NiO particles would show enhanced performance through better electrochemical reactivity at the surface on the LIB electrode. |
