Background
In recent years, rapid development in the field of new energy power generation puts new requirements on matched energy storage systems. In the updating and upgrading of energy storage batteries, lithium ion batteries have become an important research field due to various advantages of the lithium ion batteries, and have been practically applied to a large number of energy storage projects to achieve certain results. However, due to environmental problems such as heavy metal pollution, water pollution and soil pollution, people feel worry about the future application prospect of LIBs. Therefore, the development and preparation of high-performance, sustainable and green electrode materials are of great importance for the application of lithium ion batteries.
Covalent organic framework Compounds (COFs) are an emerging class of porous crystalline materials, have a periodic two-dimensional or three-dimensional network structure, and are crystalline porous materials formed by connecting organic structural units with dynamic covalent bonds. Since the first example of COFs reported by Yaghi in 2005, many new COFs have emerged. Because COFs materials have ordered and controllable pore structures, permanent porosity, large specific surface area, post-modified active groups, high thermal stability, high chemical stability and other unique properties, the COFs materials have wide application prospects in multiple fields of gas adsorption and storage, separation, catalysis, sensing, drug delivery, energy storage, photoelectric devices and the like. To date, COFs have also been widely reported as electrode materials because of their large number of redox active centers, higher stability, long-range ordered open channels, and low solubility, which contribute to the diffusion path of ions/electrons through nanoporous channels. However, COFs materials also suffer from the following disadvantages: (1) compared with an inorganic molecular sieve, the material synthesized by the method of boric acid self-polymerization and boric acid ester formation is easy to decompose when meeting water, has poor stability and is not beneficial to the wide application of the material; (2) the challenges of finding a new rigid framework, developing a new connection mode and designing and synthesizing COFs materials with novel structural properties are also faced at present; (3) most COFs materials are synthesized under solvothermal conditions, so that the operation difficulty is high, the requirements on reaction conditions are strict, the large-scale synthesis of the COFs materials is limited, and the industrial application of the COFs materials is further hindered. At present, the method which is simple and easy to operate and can synthesize a large amount of COFs materials is urgent; (4) designing and synthesizing functionalized COFs materials and realizing application research of the materials in different fields are also a challenge. The COF negative electrode material for the lithium ion battery in the existing scheme has the problem of poor stability, so that the use performance of the COF negative electrode material is influenced, the existing modification process is more complicated, more equipment is involved, the process is more complicated, and the control on the production of products is not favorable, so that the COF negative electrode material has very important practical significance for improving the simplification of COFs materials and processes.
