Taking advantage of synergistic effects, the ternary metal oxides have attracted tremendous interest. Herein, ZnMnO nano-particles have been fabricated a facile one-step approach at room temperature, that of simply mixing ZnO and MnO in KOH aqueous solution without templates. When used as an anode for lithium ion batteries, it delivers the excellent structure stability (1028.9 mA h g at 1.0 A g after 400 cycles). Surprisingly, the low-cost and eco-friendly route provides a novel strategy to synthesize the mixed transition metal oxide electrodes with readily scaled-up production.
利用协同效应，三元金属氧化物引起了极大的关注。在此，通过一种简便的室温一步法制备了ZnMnO纳米颗粒，即在无模板的情况下，将ZnO和MnO简单地混合在KOH水溶液中。当用作锂离子电池的阳极时，它具有出色的结构稳定性（在1.0 A g下循环400次后，容量为1028.9 mA h g）。令人惊讶的是，这种低成本且环保的方法为合成易于大规模生产的混合过渡金属氧化物电极提供了一种新策略。
