Silicon is increasingly recognized as a promising candidate for the next generation of high-capacity anodes in lithium-ion batteries. However, its substantial volumetric changes during charge and discharge cycles significantly reduce battery lifespan, which hampers its further development and practical application. Developing novel binders represents a critical strategy to overcome these challenges. PG (modified gallic acid crosslinked polyvinyl alcohol) exhibited excellent adhesion (1.28 N) and mechanical strength (89 MPa). Moreover, at a current density of 420 mA·g^-1, the PG55 (polyvinyl alcohol: modified gallic acid = 50:50 wt %) electrode maintained an impressive specific capacity of 2480 mAh·g^-1 after 100 cycles. Further increasing the current density to 840 mA·g^-1, the PG55 electrode retained a capacity of 1822 mAh·g^-1 after 200 cycles, while maintaining high coulombic efficiency throughout the cycling process. This study provides a significant reference for the ongoing evolution of binders applied for silicon anode.
