? 2022 Elsevier B.V.Herein, a unique dodecahedron composite material of Zn-Co bimetallic zeolitic imidazolate frameworks (ZIFs) and carbon nanotubes (CNTs) is synthesized by a simple room temperature static precipitation-annealing process. As an anode material for lithium-ion batteries (LIBs), the designed nanomaterials exhibits excellent lithium storage performance and cycle performance. It demonstrates a high discharge specific capacity of 720.9 mAh g-1 at 100 mA g-1. Besides, a high reversible capacity of 608.7 mAh g-1 at a current density of 500 mA g-1 after 300 cycles. The significant improvement in the electrochemical performance of Zn/Co-ZIFs/CNTs nanocomposite can be attributed to the strong synergy between Zn/Co-ZIFs and CNTs.
