Silicon is attracting a lot of attention as the promising alternative to traditional graphite anode materials of the Lithium-ion battery because of high theoretical capacity( 3579mAh / g ). However, a significant volume change during cycling and low conductivity due to the semiconductor properties of silicon problems are preventing commercialization. Conductive polymer binders can do dual roles as both a binder and a conducting agent. This dual functionality not only increases the proportion of active materials in the electrode but also elevates the volumetric energy density of current Li-ion batteries. Also, it can promote homogeneous electron transfer within the whole electrode. In this study, we explore the potential of PEDOT:PSS and its treatment effect in silicon anode. To investigate this, electrochemical performance, GIWAS analysis for mechanism of conductivity enhancement was measured. Also, the actual cycling was observed by in-situ OM
