| 内容記述 | A series of lithium-containing oxides with V3+ and Mn3+ ions are proposed as emerging high-capacity positive electrode materials for lithium-ion batteries. These oxides are typically synthesized by a calcination process in an inert atmosphere. For the successful synthesis of these materials, the strict control of oxygen partial pressure is necessary to prevent partial oxidation of materials during calcination. In this article, a simple methodology used in laboratory-scale material production, i.e., an oxygen trap by Cu foil, is described to synthesize phase pure oxides, which are easily oxidized on calcination. To demonstrate the benefit of the methodology, Li8/7Ti2/7V4/7O2 and Li8/7Ti2/7Mn4/7O2 are selected as lithium-containing oxides with V3+ and Mn3+ ions, respectively. Single phase oxides are successfully obtained from the pellets calcined with Cu foil, whereas partially oxidized phases are obtained for the pellets calcined without Cu foil. Moreover, phase-pure oxides synthesized with Cu foil show much better performance as positive electrode materials for battery applications. This methodology is also expected to be applied for material synthesis for diverse applications. A simple methodology to synthesize easily oxidized materials with Mn3+ and V3+ ions, which are used as emerging high-capacity positive electrode materials for lithium-ion batteries, is proposed. | |||||||||||
