Tungsten Oxide Nanorod
Since indium storage property of nanocrystalline transition metal oxide (MO,M=Co, Ni, Cu, Fe) is found, other transition metal oxide such as CuO, Fe 2 O 3 , Fe 2 O 4 , Co 3 O 4 , WO 3 can be transited by chemical reaction MOx+2xLi+=M+xLi 2 O. Its capacity is far better than graphite anode material in lithium ion battery. Among which WO3 is the most stable oxide of tungsten under room temperature. It is not only environmental friendly, but also is cheap. It has potential to be widely applied as lithium ion battery anode material. However, tungsten oxide in lumpish has low electric conductivity, its volume changes greatly during charge-discharge process. Thus results in the instability of WO3. One of the improving methods is to synthesis WO3 nano material of different appearance. Then lithium storage property of the material is improved. Preparing method: By hydrothermal method, tungsten oxide nanorod can be prepared on the indium tin oxide substrate. Raw material: Sodi...
