Abstract Hybrid organic–inorganic materials, particularly with a framework structure, have recently attracted much attention as redox electrode. In this work, we report for the first time, the electrochemical properties of redox-active organic molecular Li-salt derived from 1,2,4-benzenetricarboxylic acid (1,2,4-H 3 BTC) as lithium-ion battery (LIB) anode. The organic molecular salt (1,2,4-Li-BTC), prepared by a simple low temperature (80 °C) solvothermal process, delivers a first cycle charge capacity of 162 mAhg −1 . Further, it is shown that preparing a composite electrode with 8 wt% MWCNT improves charge transport and alleviates the dissolution problem, resulting in steady cycling behaviour and good rate performance. The results show promise for this new class of anode with flat charge discharge profiles and a convenient working potential of ∼1.2 V vs. Li + /Li.

1,2,4-苯三羧酸的氧化还原活性有机分子盐作为锂离子电池负极

摘要 混合有机-无机材料，特别是具有框架结构的材料，最近作为氧化还原电极受到了广泛关注。在这项工作中，我们首次报道了源自 1,2,4-苯三甲酸（1,2,4-H 3 BTC）的氧化还原活性有机分子锂盐作为锂离子电池的电化学性能（ LIB) 阳极。通过简单的低温 (80 °C) 溶剂热工艺制备的有机分子盐 (1,2,4-Li-BTC) 提供了 162 mAhg -1 的第一次循环充电容量。此外，研究表明，制备具有 8wt% MWCNT 的复合电极可改善电荷传输并减轻溶解问题，从而实现稳定的循环行为和良好的倍率性能。
