A cheap Si powder byproduct from solar cell production was applied as a negative electrode for lithium-ion batteries. To improve the cycle and rate performances, the as-obtained Si powder was composited with tungsten oxide and coated with carbon, in sequence. After preparing the composite material, its electrochemical performance is evaluated, which exhibits a high reversible capacity of 975mAhg−1...
In this study, polarization behavior during initial lithiation step was comparatively investigated using a tungsten oxide (WO3) and its reduced one (WO3−x). Ex-situ X-ray diffraction revealed that the overall lithiation process in WO3 was mostly similar to that of WO3−x, which was associated with the typical conversion reaction of transition-metal oxide. In the WO3−x anode, however, insertional lithiation...
