Reversible lithium-ion insertion in triclinic hydrated molybdenum oxide nanobelts

Up to the present, little success has been achieved using hydrated metal oxides as high-performance LIB anodes, which is impeding their extensive study and their wide applicability. Herein, we for the first time study the electrochemical Li storage properties of the little-studied triclinic hydrated molybdenum oxide MoO3 center dot xH(2)O. Without any special efforts, such as nanosizing or carbon coating, the triclinic system MoO3 center dot xH(2)O nanobelts deliver very high initial Coulombic efficiency (e. g., 98.3%) and high durable reversible Li storage capacities (e. g., 1176 mA h g(-1)). In light of the urgent demand for energy-storage, we hope our endeavor could blaze a new path, using hydrated metal oxides as anodes, in developing novel high-performance LIBs anodes.
