NPGDA (Neopentyl glycol diacrylate, >95%} as Crosslinking Monomer for Gel Polymer Electrolyte, 50-200 g/bottle, CGPECMNPGDA

Neopentyl glycol diacrylate (NPGDA) is a bifunctional aliphatic acrylate monomer (C8H12O4) featuring two reactive acrylate (CH2=CHCOO-) groups attached to a hindered, symmetrical neopentyl glycol core (-CH2-C(CH}3)2-CH2-). In advanced energy storage research, NPGDA is utilized as a high-reactivity, rigid-core crosslinking agent for Gel Polymer Electrolytes (GPEs) and in situ polymerized solid/gel battery systems, delivering rapid curing kinetics, high chemical resistance, and robust mechanical rigidity for high-energy lithium and sodium metal batteries.

The main functional roles of NPGDA in GPEs are: (1) Rigid 3D Network & Liquid Immobilization: Upon thermal or UV-initiated radical polymerization (using initiators like AIBN, BPO, or photoinitiators), NPGDA crosslinks into a tightly knit 3D network that permanently traps and immobilizes organic liquid electrolytes. This eliminates free-flowing liquid leakage, converting high-energy liquid cells into safe, dimensionally stable gel systems. (2) Enhanced Mechanical Modulus & Suppressed Dendrite Penetration: Due to the sterically hindered, compact neopentyl core, NPGDA-based networks exhibit a higher shear modulus and mechanical rigidity than flexible polyether-based diacrylates. This creates a stiffer physical barrier that effectively resists sharp lithium or sodium dendrite propagation during fast-charging cycles. (3) High Thermal & Electrochemical Stability: The robust aliphatic ester backbone resists oxidative degradation at elevated voltages, helping maintain structural integrity when paired with high-voltage cathodes or operated at elevated temperatures.
