XG (Xanthan Gum) Powder as Battery Electrode Binder, 100 g/bottle, CBEBXG

XG (Xanthan Gum) is a highly promising, bio-based material being actively researched as an eco-friendly and high-performing binder for next-generation batteries, particularly as a replacement for the traditional Polyvinylidene Fluoride (PVDF) binder. Xanthan gum is a natural polysaccharide with a complex structure.4 Its backbone and trisaccharide side chains contain numerous hydroxyl (-OH) and carboxylic (-COOH) groups. These functional groups allow it to form strong hydrogen bonds and electrostatic interactions with the active materials (like graphite or silicon) and the metal current collector (e.g., copper foil). Studies on graphite anodes have shown that XG can exhibit better binding performance and larger plastic deformation resistance compared to PVDF. Moreover, XG-based electrodes often demonstrate a lower charge transfer resistance and more active kinetics at the electrode/electrolyte interface, which is beneficial for the movement of lithium ions
