The invention discloses a preparation method and application of an ion gel electrolyte based on a covalent organic framework, and belongs to the technical field of quasi-solid-state battery electrolytes. 50%, rigid covalent organic framework 10‑35%, and the balance is ionic liquid. Among them, the rigid covalent organic structure has high pore volume, specific surface area and extremely low density, so it can absorb more ionic liquid electrolytes, which is beneficial to improve the ionic conductivity of quasi-solid electrolytes. In addition, the ion gel electrolyte has a rigid frame structure, which is beneficial to inhibit the growth of dendrites such as lithium and sodium, and improves the safety of ion gel batteries. Therefore, the electrolyte has potential application prospects in the development of alkali metal batteries. |
