Herein, a synthetic strategy for growing trimetallic zeolitic imidazolate framework (ZIF) polyhedrons on copper foam (CF) and interweaving with copper nanowires (CNWs) is proposed. Subsequently, in situ annealing under N2 atmosphere leads to the formation of multi-doped CNWs/Cu0.39Zn0.14Co2.47O4-ZnO/CF (CNWs/CZCOZ/CF). The unique structural characteristics of CNWs/CZCOZ/CF allow it to be directly assembled as a working electrode, without additional conductive additives or binders. When it's used as the lithium-ion battery (LIB) anode, this electrode exhibits a significantly high capacity of 2305 mAh g-1 at 0.1 A g-1 after 500 cycles. More importantly, kinetic analysis on the basis of cyclic voltammograms (CVs) indicates that the pseudocapacitive effect is the primary contributor to the high lithium storage capacity and also accounts for the exceptionally high rate capacity of 713 mAh g-1 even if the current density is at a maximum of 10 A g-1. Moreover, the superior battery performance originates from their advantageous structural diversity and unique compositional features, including synergistic effects among polymetallic components and two highly conductive substrates (CNWs and CF), forming unhindered paths for fast charge transfer.

沸石咪唑酸酯骨架衍生的阳极材料中的铜纳米线和泡沫铜多功能桥，可实现出色的锂存储。

本文提出了一种在泡沫铜（CF）上生长三金属沸石咪唑酸酯骨架（ZIF）多面体并与铜纳米线（CNW）交织的合成策略。随后，在N 2气氛下原位退火导致形成多掺杂CNWs / Cu0.39Zn0.14Co2.47O4-ZnO / CF（CNWs / CZCOZ / CF）。CNW / CZCOZ / CF的独特结构特征使其可以直接组装为工作电极，而无需额外的导电添加剂或粘合剂。当用作锂离子电池（LIB）阳极时，该电极在500次循环后在0.1 A g-1的条件下显示出2305 mAh g-1的极高容量。更重要的是，基于循环伏安图（CV）的动力学分析表明，假电容效应是高锂存储容量的主要贡献者，即使电流密度最大，其假想容量也高达713 mAh g-1。 10 A g-1。此外，卓越的电池性能源于其有利的结构多样性和独特的成分特征，包括多金属成分与两个高导电性基材（CNW和CF）之间的协同效应，形成了不受阻碍的快速电荷转移路径。
