ZnO/Co3O4/C hollow dodecahedrons derived from ZnCo-ZIFs as anode materials for lithium ion batteries

The bimetal oxides (ZnO/Co3O4/C) showed superior Li' storage performances as anode materials for Lithium ion batteries (LIBs). The ZnO/Co3O4/C hollow dodecahedrons have been successfully synthesized via ZnCo-ZIFs as self-sacrificial template. The ZnO/Co3O4/C hollow dodecahedrons were applied in the anode materials, which have shown outstanding Li+ storage performances. The ZnO/Co3O4/C electrodes have shown a high discharge capacity (1316 mA h g(-1) at 0.1 A g(-1) after 100 cycles) and high rate performances (1101 mA h g(-1) at 1 A g(-1) after 25 cycles). The excellent Li' storage performance of ZnO/Co3O4/C hollow dodecahedrons mainly benefited from its unique hollow structure and the synergistic effect of multicomponent. (c) 2020 Elsevier B.V.
