%X 近年来，过渡金属氧化物已被认为是最有希望代替贵金属作为锂氧(Li-O2)电池阴极催化剂的材料。本文研究了一种由静电纺纤维煅烧后自发形成的MnO纳米颗粒作为Li-O2电池的高效催化剂。物性表征的结果显示成功合成了平均粒径为61.82 nm的MnO纳米颗粒，为立方晶系结构，作为Li-O2电池阴极在500次循环中表现出优异的循环稳定性，首次充电过电位为0.46 V，在500 mA·g−1的高电流密度下实现了1000 h的稳定循环，优于大多数已报道的用于Li-O2电池的MnOx催化剂。
In recent years, transition metal oxides have been considered the most promising materials to replace precious metals as cathode catalysts for lithium-oxygen batteries. This study investigates MnO nanoparticles that spontaneously form after calcining electrospun fibers as an efficient catalyst for lithium-oxygen (Li-O2) batteries. Physical characterization shows that MnO nanoparticles with an average particle size of 61.82 nm and a cubic crystal structure were successfully synthesized. They exhibit excellent cycling stability as a cathode in Li-O2 batteries, enduring over 500 cycles with an initial overpotential of 0.46 V. Concurrent, they also achieve stable cycling for 1000 hours at a high current density of 500 mA·g−1, outperforming most reported catalysts such as MnOx for Li-O2 batteries.
