可持续和资源丰富的有机材料是锂离子电池的长期利益。然而，结构稳定性和循环性能的不足仍然是其实用化的瓶颈。在这里，两个新的化学稳定的萘酰亚胺基结晶共价有机框架（COFs）首次通过简单的溶剂热路线合成。作为锂离子电池的正极材料，其优异的电化学性能主要归因于其开放有序的纳米多孔骨架和坚固的结构。此外，它们的电化学性能可以通过简单地在分子水平上改变COFs的连接基团来改善。本工作为有机材料的结构调控提供了一种可能的途径。
Sustainable and resourceful organic materials are of long-standing interest for lithium-ion batteries. However, the lack of structural stability and cyclic capability is still the bottleneck for their practical use. Here, two new chemically stable naphthalimide-based crystalline covalent organic frameworks (COFs) were first synthesized through a simple solvothermal route. Excellent electrochemical performances were achieved as cathode materials for Li-ion batteries, mainly due to their open ordered nanoporous framework and robust structure. Moreover, their electrochemical performance can be improved by simply altering the linker of COFs at the molecular level. This work provides a possible approach to obtain the desired performance by structural modulation of organic materials.
