MBAM {N,N′-Methylenebis(acrylamide)} as Monomer for Gel Polymer Electrolytes (GPEs), 100 g/bottle, CGPEMMBAM

N,N′-Methylenebis(acrylamide) (MBAM or MBAA) is a highly effective bifunctional crosslinking agent widely utilized in fabricating Gel Polymer Electrolytes (GPEs) for next-generation energy storage systems (including lithium-ion, sodium-ion, and zinc-metal batteries). Because it contains two terminal vinyl groups (CH2=CH-), it bridges polymer chains during in-situ or ex-situ polymerization, turning a liquid monomer solution into a robust, three-dimensional (3D) interconnected polymer network capable of trapping large volumes of liquid electrolyte.

The key Functions of MBAM in GPEs are shown below: (1) 3D Network Architecture: MBAM provides the structural crosslinking points needed to anchor linear polymer matrices—such as poly(acrylic acid) (PAA), polyacrylamide (PAM), or poly(methyl methacrylate) (PMMA)—preventing the polymer from dissolving into the liquid electrolyte. (2) High Electrolyte Uptake & Retention: The resulting porous 3D framework effectively locks in liquid organic carbonates, ionic liquids, or aqueous electrolytes via capillary action and polymer-solvent interactions, maintaining high ionic conductivity near that of liquid electrolytes. (3) Suppressing Dendrites: The enhanced mechanical modulus of an MBAM-crosslinked framework offers a physical barrier that helps suppress lithium or sodium dendrite penetration, mitigating short circuits. (4) In-Situ Polymerization Compatible: Its high reactivity allows it to undergo thermal or ultraviolet (UV) initiated free-radical polymerization directly inside a sealed cell, ensuring conformal, low-resistance interfaces with porous electrodes.

The key electrochemical features of the MBAM-based GPEs: (1) Voltage Stability Window: MBAM-based frameworks (particularly acrylamide derivatives) generally exhibit good anodic stability up to around 4.2V to 4.5V vs. Li/Li+. However, at higher voltages or elevated temperatures, the amide groups (-C(=O)-NH-) can undergo oxidative decomposition. (2) Passivation Layer Interaction: In alkali metal batteries (Li/Na), residual trace monomers or unreacted double bonds can react with the highly reducing metal anode, impacting the stability of the Solid Electrolyte Interphase (SEI). Ensuring complete conversion during the initiation step is necessary for long-term cycling stability.
