| 英文摘要 | Conventional binders in the cathode of Li-O-2 batteries are insulated, and integrate with the catalyst and the conducting carbon-support by physical mixing. This limits the transfer of electrons, degrades the cathode structure due to swelling, and finally leads to capacity fading and is deleterious to cycleability. In this study, we realized, for the first time, a one-step fabricated Co3O4-PPy cathode characterized by an in-situ formed conductive polymer binder. The functional binder, polypyrrole (PPy), was synthesized through electrical method, which acted as both the binder and supporting material in the Li-O-2 battery. Based on the conductive property of PPy, we obtained the Co3O4-PPy@Ni electrode via the process of CV electro-deposition. This method results in uniform distribution of Co3O4 nanoparticles and can simplify the preparation process of the air cathodes. The Li-O-2 battery with the Co3O4-PPy@Ni cathode can discharge/charge for over 30 cycles under the limited specific capacity of 1000 mAh/g. The cycleability and impedance spectra of the Li-O-2 battery with the functional binder of PPy are superior to the battery with conventional binders. |
