Flexible/Rechargeable Zn-Air Batteries based on Multifunctional Heteronanomat Architecture |
| 초록 |
We demonstrate a new class of flexible/rechargeable Zn-air batteries based on multifunctional heteronanomat architecture. Heteronanomat (denoted as “HM”) framework-supported electrodes are fabricated through one-pot electrospraying (for electrode powders/carbon nanotube (CNT)) and electrospinning (for polyetherimide (PEI) nanofibers) process. Zn powders (in anodes) and rambutan-shaped cobalt oxide (Co3O4)/carbon nanotube (CNT) composite powders (in cathodes) are used as electrode active materials. The Zn (or Co3O4/CNT) powders are densely packed and spatially bound by the all-fibrous HM frameworks that consist of PEI nanofibers (for structural stability)/CNT (for electrical conduction) networks, leading to formation of three-dimensional (3D) bicontinuous ion/electron transport channels in the electrodes. Benefiting from its unique structure and functionalities, the HM-structured Zn-air cell significantly improves mechanical flexibility and electrochemical rechargeability. |
