Gelatin Powder as Battery Electrode Binder, 100 g/bottle, CBEBG

Gelatin) is naturally "sticky." Its molecular structure is rich in polar functional groups, including amino (-NH2), carboxyl (-COOH), and hydroxyl (-OH) groups. When adsorbed onto graphite or silicon, gelatin adopts a "hairy" configuration with loops and tails sticking into the solution. This creates a powerful steric stabilization effect, ensuring that active material and carbon black are perfectly and uniformly dispersed. It forms strong hydrogen and coordination bonds with the current collector. Studies have shown that even a small amount of gelatin (as low as 2 wt%) can provide better cyclability and rate capability than traditional PVDF. Moreover, gelatin molecules can be cross-linked into a triple-helical network. This structure acts like a spring group system, effectively absorbing and dissipating the massive mechanical stress caused by silicon's 300% volume expansion.
