A composite of manganese monoxide loaded onto carbon nanotubes (CNTs@MnO) has been synthesized by a facile approach, in which the CNTs form a continuous conductive network connecting the electrocatalyst MnO nanoparticles together to facilitate good electrochemical performance. The electrocatalyst MnO shows favourable rechargeability, and good phase and morphology stability in lithium oxygen batteries. Excellent cycling performance is also demonstrated, in which the terminal voltage is higher than 2.4 V after 100 cycles at 0.4 mA cm(-2), with 1000 mAh g(-1)(composite) capacity. Therefore, this hybrid material is promising for use as a cathode material for lithium oxygen batteries.
通过一种简便的方法合成了负载在碳纳米管上的一氧化锰复合材料(CNTs@MnO),其中碳纳米管形成了一个连续的导电网络,将电催化剂MnO纳米颗粒连接在一起,以促进良好的电化学性能。电催化剂MnO在锂氧电池中表现出良好的可再充电性以及良好的相稳定性和形态稳定性。还展示了优异的循环性能,在0.4 mA cm(-²)的电流密度下循环100次后,终端电压高于2.4 V,具有1000 mAh g(-¹)(复合材料)的容量。因此,这种混合材料有望用作锂氧电池的正极材料。
