CCMA {(2-oxo-1,3-dioxolan-4-yl)methyl methacrylate} as Monomer for Gel Polymer Electrolytes (GPEs), 5 g/bottle, CGPEMCCMA

(2-oxo-1,3-dioxolan-4-yl)methyl methacrylate, commonly known as cyclic carbonate methacrylate (CCMA), is an advanced functional monomer used to synthesize high-performance gel polymer electrolytes (GPEs). Its main appeal lies in its molecular mimicry of traditional liquid battery solvents, enabling solid-state-like safety without sacrificing the rapid ion transport of liquid systems.

The molecular architecture of CCMA is strategically divided into two functional domains: CH2=C(CH3)-COO-CH2-CH(O-COO-CH2). (1) The Methacrylate Backbone: The polymerizable C=C double bond allows for rapid free-radical polymerization (typically initiated thermally by AIBN or via UV curing). This creates a mechanically robust polymethacrylate main chain. (2) The Cyclic Carbonate Pendant Group: The side chain features a 5-membered cyclic carbonate ring. This group is chemically identical to ethylene carbonate (EC), the primary high-permittivity solvent used in conventional lithium-ion and sodium-ion liquid electrolytes.

The structural advantages of CCMA in gel polymer electrolytes (GPEs): (1) Unprecedented Liquid Electrolyte Retention: A major failure mode of conventional GPEs (like PMMA or polyacrylonitrile) is "syneresis"—the liquid electrolyte gradually bleeds or squeezes out of the polymer matrix over time, leading to cell dry-out. Because the cyclic carbonate side chains on poly(CCMA) share the exact same chemical structure as EC, the polymer matrix exhibits high thermodynamic affinity for carbonate-based liquid electrolytes (EC, DMC, EMC). It swells extensively and securely locks in the liquid phase through strong dipole-dipole interactions, preventing leakage even under elevated pressures or mechanical cell deformation. (2) Enhanced Cation Dissociation & Transport: In standard polymer hosts like PEO, lithium or sodium ions are heavily coordinated by ether oxygens, which restricts their mobility. The cyclic carbonate groups in CCMA possess a high dielectric constant, giving them an exceptional ability to screen the Coulombic attraction between salt anions (like PF6- or TFSI-) and metal cations (Li+ or Na+). This facilitates salt dissociation, resulting in a high concentration of free, mobile charge carriers and an improved cation transference number. (3) Superior Wetting & Low Interfacial Resistance: When utilized in in situ polymerization workflows, the low-viscosity CCMA precursor liquid easily flows into the sub-micron pores of the cathode, anode, and separator. Because of its structural similarity to the liquid electrolyte components, it ensures rapid and complete wetting of the active material surfaces before it is crosslinked into a gel. This minimizes the interfacial impedance at the solid-to-gel boundaries.
