| 제목 | Electrochemical Properties of Ordered Mesoporous Cobalt Oxides as a Negative Electrode for Li-ion Battery |
| 초록 | In recent days, as cutting-edge devices, such as cell phone, EV and ESS, become more sophisticated, the battery performance is required to be higher. As a result, metal oxides having a capacity several times larger than that of carbon have attracted attention as a candidate for a next-generation secondary battery. Cobalt oxide(CoO) is very attractive anode material due to its relatively high theoretical capacity of 716 mAh/g. The nanostructured materials, especially mesoporous structure can play a leading role in electrochemical properties since its high surface area, large surface-to-volume ratio, and stable buffer effect against volume expansion. These characteristics provide especially anode materials with a lot of advantages which are fast ion/electron transfer, sufficient contact interface between active materials and electrolyte. Although bulk CoO maintains its own stable phase, mesoporous CoO gradually forms Co3O4 with Co metal through disproportionation process. |
