| 内容記述 | We have reported the effects of substituting a transition metal in silicide on the electrochemical performance of the silicide/Si composite anode for lithium-ion batteries (LIBs); the Cr0.5V0.5Si2/Si electrode exhibited much better cyclability compared with CrSi2/Si and VSi2/Si electrodes. Herein, we investigated the electrochemical performance of a CrxV1–xSi2/Si slurry electrode for its application in LIBs, and the results obtained were compared to those of a gas deposition (GD) electrode, which was comprised of only active materials. The slurry electrode exhibited a superior cycling life as with the GD electrode. After charge–discharge cycles, the expansion of the electrode thickness of CrSi2/Si and Cr0.5V0.5Si2/Si was smaller than that of VSi2/Si, and VSi2 was significantly pulverized compared with the other silicides. It is considered that VSi2 deformed easily by the stress from Si expansion and pulverized because the hardness of VSi2 was the smallest among the silicides used in this study. These results reveal that Cr0.5V0.5Si2/Si has great potential as an anode material for next-generation LIBs and hardness is an important property for compositing silicide with Si. | |||||
