SA (Sodium Alginate) Powder as Battery Electrode Binder, 100 g/bottle, CBEBSA

SA (Sodium Alginate) has rich hydroxyl (-OH) groups and sodium carboxylate (-COONa) groups. This high density of polar, oxygen-containing groups allows SA to form powerful hydrogen bonds with the surface oxides (SiOx or TiO2) of the active material. These rigid, multi-point bonds provide exceptionally strong adhesion and cohesion, which is critical for electrode integrity. The rigid, chain-like structure and strong hydrogen bonding network of SA are effective at holding the expanding and contracting Si particles together. This prevents particle pulverization and maintains the electrical pathway, leading to enhanced cycling stability and capacity retention compared to PVDF.
