PAM (Polyacrylamide) Powder as Battery Electrode Binder, 100 g/bottle, CBEBPAM

PAM (Polyacrylamide) a water-soluble polymer that offers excellent adhesion and the ability to be structured into robust networks, making it a strong candidate to replace traditional binders like PVDF. The most significant advantage of PAM is its ability to be easily cross-linked into a 3D network or hydrogel structure (c-PAM). This cross-linked network provides superior mechanical strength, high elasticity, and high stretchability. This is vital for silicon anodes, which undergo massive volume changes (up to 300%) during lithiation/delithiation. The robust PAM network acts as a buffer, preventing the active material particles from fracturing and losing electrical contact. Moreover, PAM chains and their derivatives contain abundant polar amide (-CONH2) functional groups. These polar groups form strong hydrogen bonds with the silanol (-SiOH) or silicon oxide (SiOx) layer naturally present on the surface of silicon particles.11 This strong chemical interaction provides the superior adhesion needed to keep the expanding particles firmly anchored to the current collector and to each other.
