| Abstract |
Sequential oxygen-nitrogen exchange (SONE) reaction is developed as a top-down approach to prepare nanostructured oxides from bulk solids. This novel synthesis method that induces grain fracture instead of grain growth at high-temperature is a simple, two-step thermal treatment that is sequentially performed in gaseous NH3 and in air. The SONE reaction can be applicable to most transition metal oxides and when utilized in a lithium-ion battery, the produced nanostructured materials are superior to their bulk counterparts and even comparable to those produced by conventional bottom-up approaches. Given its simplicity and scalability, this synthesis method could open a new avenue to the development of high performance nanostructured electrode materials that can meet the industrial demand of cost-effectiveness for mass production. |
