Abstract

Co3O4/CuO hybrid hollow microspheres have been successfully prepared via thermal decomposition of CoCu glycolates, whose size can be adjusted by varying the molar ratio of Co2+/Cu2+. As lithium-ion battery (LIB) anode, Co3O4/CuO microspheres exhibited excellent electrochemical performance due to synergistic effects and the hollow structural design, the best Co3O4/CuO sample could maintain a high specific capacity of 1170.4 mAh g-1 after 300 cycles at 1 A g-1, and still retain a capacity of 514.5 mAh g-1 after 1000 cycles at 2 A g-1. Thus obtained Co3O4/CuO hybrid hollow microspheres hold great potential as anode materials for high-performance LIBs.

将 Co3O4/CuO 混合中空微球用作长循环寿命锂离子电池阳极

通过热分解 CoCu 乙二醇盐成功制备了 Co3O4/CuO 混合空心微球，其尺寸可通过改变 Co2+/Cu2+ 的摩尔比进行调节。作为锂离子电池（LIB）正极，Co3O4/CuO 微球因协同效应和中空结构设计而表现出优异的电化学性能，最好的 Co3O4/CuO 样品在 1 A g-1 下循环 300 次后仍能保持 1170.4 mAh g-1 的高比容量，在 2 A g-1 下循环 1000 次后仍能保持 514.5 mAh g-1 的容量。因此，所获得的 Co3O4/CuO 混合空心微球作为高性能 LIB 的负极材料具有巨大的潜力。

期刊介绍： Chemistry—An Asian Journal is an international high-impact journal for chemistry in its broadest sense. The journal covers all aspects of chemistry from biochemistry through organic and inorganic chemistry to physical chemistry, including interdisciplinary topics. Chemistry—An Asian Journal publishes Full Papers, Communications, and Focus Reviews. A professional editorial team headed by Dr. Theresa Kueckmann and an Editorial Board (headed by Professor Susumu Kitagawa) ensure the highest quality of the peer-review process, the contents and the production of the journal. Chemistry—An Asian Journal is published on behalf of the Asian Chemical Editorial Society (ACES), an association of numerous Asian chemical societies, and supported by the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society), ChemPubSoc Europe, and the Federation of Asian Chemical Societies (FACS).
