Infilling of Gel Polymer Electrolytes into Thick Porous Electrodes for Supercapacitors |
| 초록 |
Gel polymer electrolytes (GPEs) provide promising opportunities for energy storage because they can offer safer operation over liquid electrolyte and remarkable electrochemical performances. Here we prepare GPEs consisting of trimethylolpropane ethoxylate triacrylate (ETPTA) and poly(ethylene glycol) methyl ether methacrylate (PEGMA), lithium salt solution (1 M LiPF6 EC/DMC) by UV curing. Both ionic conductivity and mechanical property are adjusted by varying the composition of ETPTA, PEGMA, and lithium salt solution in the GPEs. Largely ion-conductive GPEs (~10-3 S/cm) with moderate mechanical robustnessis infilled into the thick electrodes with large mass loading (＞5 mg/cm2)that can enhance the interface properties of the electrode-electrolyte. While GPEs with good mechanical stability and relatively small ionic conductivity (~10-4 S/cm) is placed over onto the electrodes and it serves as both separator and electrolyte. |
