Cellulose-Based Ionogels for Renewable Flexible Supercapacitors |
| 초록 |
A renewable cellulose-based dual network ionogel electrolyte is synthesized by modifying a microcrystalline cellulose network in a tailor-made 1,3-dimethylimidazolium methyl phosphite [DMIM][MeO(H)PO3] ionic liquid and subsequently polymerizing 2-hydroxyethyl methacrylate monomer in the presence of a modified cellulose network. The as-synthesized ionogel electrolytes exhibit high ionic conductivity (2.6–22.4 mS cm−1) over a wide temperature range (30–120 °C), with a maximum toughness of 1.46 MJ m−3 at 30 °C. A renewable flexible supercapacitor is fabricated by sandwiching the cellulose-based ionogel electrolyte between two activated carbon electrodes, delivering high specific capacitance and rate capability of 174 F g−1 and 88% at 120 °C at a cell voltage of 2.5 V. |
