Morphologically controlled synthesis and applications of metal-doped manganese oxide nanostructures

摘要

In this work, we present the morphologically controlled synthesis of metal-doped manganese oxide (M-Mnx0y) nanostructures and their application for Li-ion battery anode. The in-situ generated CO_3~(2-) from the oxidation of organic compounds is the key parameter to control the morphology of peanut-like metal-doped MnCCb. After calcination at various temperatures, M-MnxOy shows the change in phase while the template morphologies are still retained. The developed synthetic protocol can be applied for various metal doping in manganese oxide structures. CoMn_2O_4 exhibits superior electrochemical performance and stability. The as-synthesized COMn_2O_4 could potentially be used in the large scale of Li-ion battery production. Keywords: metal-doped manganese oxide, manganese carbonate, manganese oxide, Li-ion battery anode
