Silane coupling agent treated copper foil as a current collector for silicon anode

Abstract

Since the volume variation of silicon particles during cycling, the binding spots between Cu current collector and silicon anode raised to be one of the critical binding problems. In this work, an amino-modified Cu current collector (Cu*) is fabricated to tackle this issue. The amino groups on Cu* surface increase its hydrophilicity, which is conducive to the curing process of aqueous slurry on its surface. Meanwhile, these amino groups can form abundant amide bonds with carboxyl groups from the adopted polyacrylic acid (PAA) binder. The combined action composed of the covalent bond and mechanical interlocking could reduce the contact loss inside the electrode. However, high concentration silane coupling agent treatment will weaken the surface roughness of Cu* and weaken mechanical interlocking. What is more, the insulation of silane coupling agent reduces the conductivity of Cu and increases the impedance of battery. Considering the effect of silane coupling agent comprehensively, electrochemical performance of Cu*−0.05% is best.
