| 英文摘要 | Flexible power sources with high energy density are crucial for the realization of next-generation flexible electronics. theoretically, rechargeable flexible zin-cair (zn-air) batteries could provide high specific energy, while their large-scale applications are still greatly hindered by high cost and resources scarcity of noble metal -based oxygen evolution reaction (oer)/oxygen reduction reaction (orr) electrocatalysts as well as inferior mechanical properties of the air cathode. combining metallic co4n with superior oer activity and co-n-c with perfect orr activity on a free-standing and flexible electrode could be a good step for flexible zn-air batteries, while lots of difficulties need to be overcome. herein, as a proof-of-concept experiment, we first propose a strategy for in situ coupling of strung co4n and intertwined n-c fibers, by pyrolyzation of the novel pearl-like zif-67/polypytrole nanofibers netwcitk rooted on carbon cloth. originating froth the synergistic effect of co4n and co-n-c and the stable 3d interconnected conductive network structure, the obtained free-standing and highly flexible bifunctional, oxygen electrode exhibits excellent electrocatalytic activity and stability for both om and orr in terms of low overpotential (310 mv at 10 ma cm(-2)) for oer, a positive half-wave potential (0.8 v) for orr, and a stable current density retention for at least 20 h, and especially, the obtained zn air batteries exhibit a low discharge charge voltage gap (1.09 v at 50 ma cm(-2)) and long cycle life (up to 408 cycles). furthermore, the perfect bendable and twistable and rechargeable properties of the flexible zn air battery particularly make it a. potentially power portable and wearable electronic device. |
