The investigation of carbon-coated and highly systematic rod-like MoxOy in anode of lithium ions battery
Abstract:Molybdenum oxides owe high theoretical capacity. However, owing to poor conductivity and unsatifactory stability of structure, Molybdenum oxides deliver relatively low capacity in pratical application. In this paper, a rod-like Molybdenum oxides coated via carbon was fist reported and utilized in anode of lithium ions battery. The composite was characterized by SEM、XRD、and galvanostatic charge-discharge measurement. SEM images shows that the regular rod-like structure was fabricated . Due to the unique structure and carbon coat, Molybdenum oxidesowes 1325 mAh/g of initial discharge capacity and corresponding 810 mAh/g of charge capacity.
Keywords: Lithium ions battery anode material Molybdenum oxides
