Polyacrylic acid (PAA)-based binders have been demonstrated to significantly enhance the cycling stability of pure silicon (Si) anodes compared to other binder types. However, there is a notable lack of systematic and in-depth investigation into the relationship between the molecular weight (MW) of PAA and its performance in pure Si anodes, leading to an absence of reliable theoretical guidance for designing and optimizing of PAA-based binders for these anodes. Herein, we select a series of PAA with varying MWs as binders for Si …
