Electrochemical Behavior of CoSb3-based Electrodes Using Binary PAni/PVDF Binder

The polyaniline (PAni)/polyvinylidene fluoride (PVDF) hybrid was served as a novel binder for CoSb3-based alloy electrode. The effect of PAni content on the electrochemical performances of the alloy electrode was investigated. It was found that the CoSb3 electrode using the binary PAni/PVDF binder exhibits higher reversible capacity than that using the single PVDF binder, especially in the initial cycles. As a result, the PAni/PVDF hybrid could be a promising binder for the alloy electrode.
