Figure 6. Electrochemical performance and structural stability of Si anodes employing polymeric branched binders. (A) Cycling performance of a Si electrode using the Si@PVA-g-10PAA binder over 1,000 cycles at a current density of 400 mA g^-1, accompanied by rate performance comparisons with various binders including PVA, PVA-g-10PAA, PVA-g-15PAA, PAA, and CMC. Adapted with permission from ref.^[89]; (B) Schematic illustration of the interaction between Si particles and the CA-g-PAA binder. Cross-sectional SEM images of Si electrodes with PAA and CA-g-PAA binders before cycling and after 5 and 50 cycles, along with corresponding cycling performance using different binders. Adapted with permission from ref.^[32]; (C) Schematic illustration and long-term cycling performance of Si/graphite composite anodes using Na-PAA/SBR and Na-PAA-g-SBR binders, demonstrating the superior stability and capacity retention imparted by the grafted binder system.
