Carbon-free cobalt oxide cathodes for lithium-oxygen batteries are fabricated via an electrodeposition-conversion process. The Co3O4-only cathodes show a remarkably reduced voltage gap (by ca. 550 mV compared to the carbon-only cathode) as well as excellent long-term cyclability.
通过电沉积-转化工艺制备了用于锂-氧电池的无碳钴氧化物正极。仅含 Co3O4 的正极具有显著降低的电压间隙(与仅含碳的正极相比约降低 550 mV)以及优异的长期循环稳定性。
