Ring opening metathesis polymerization (ROMP) is well-known to synthesize well-defined polymers with controlled molecular weight and narrow molecular weight distribution. Herein, we investigated the potential of ROMP-based polymers for Si anode binders to alleviate the volume expansion during charge and discharge. A series of polynorbornene network polymers comprising carboxylic acid side chains were synthesized by ROMP with third-generation Grubbs catalyst and subsequently cross-linked. The molecular weight and crosslink density of the polymer networks were systematically altered to investigate the effect of each component on the mechanical and adhesion properties of the binders, and the resulting cycling stability of the Si anode
