Conducting Polymer based Hybrid networks for Ultrahigh Volumetric Multivalent ion Pseudocapacitance |
| 초록 |
High volumetric energy density are demanding for space-limited applications. Supercapacitors have better cyclic and power capabilities compared to batteries, but restricted for low volumetric capacity due to low density of active materials (＜ 0.75 g/cc of AC) and intrinsic non-Faradaic charge storage process. To surplus these challenges, we first demonstrate ultrahigh volumetric capacitance of conducting polymer based hybrid material networks through the multivalent pseudocapacitance with significant durability. The electrochemistry of multivalent ion storage within the designed conducting polymer matrix was deeply investigated by in-situ ATR-FTIR spectroscopic analysis. Additionally, this unique electrochemistry was examined through in-situ 2D IR COS and PCA analyses. The obtained results inspire to design similar other new hybrid materials and put forth new avenue to design high volumetric capacitive materials for multivalent charge storage. |
