Developing anode materials with excellent cycling performance and energy capacities for lithium-ion batteries (LIBs) is a challenging task. Herein, we report the synthesis of an imine-linked covalent organic framework (COF) containing redox-active dehydrobenzoannulene (DBA) units. The bulk DBA-COF 3 system exhibits a reversible capacity of 207 mA h g⁻¹ at 50 mA g⁻¹ after 90 cycles. This work highlights the potential of utilizing DBA units to construct efficient organic-based anode materials for LIBs.

基于脱氢苯并环戊二烯的二维共价有机骨架作为锂离子电池的负极材料

开发具有出色循环性能和能量容量的锂离子电池（LIB）负极材料是一项艰巨的任务。在此，我们报告了包含氧化还原活性脱氢苯并环戊烯（DBA）单元的亚胺连接的共价有机骨架（COF）的合成。在90个循环后，大容量DBA-COF 3系统在50 mA g ^-1下表现出207 mA hg ^-1的可逆容量。这项工作强调了利用DBA单元为LIB构造高效的有机阳极材料的潜力。
