Article summary:
1. Lithium-sulfur (Li-S) batteries are a promising option for electrical energy storage due to their high energy density and low cost.
2. Covalent organic frameworks (COFs) have been widely used as electrode materials in Li-S batteries, with advantages such as low density, large specific surface area, adjustable pore size and structure, easy functionalization and plentiful combinations of covalent structures.
3. Different strategies have been developed to solve the bottlenecks of Li-S batteries, such as physical sulfur fixation, increasing conjugation system to increase sulfur loading, introducing electron-rich heteroatoms or functional groups to fix polysulfides, mixing highly conductive carbon-based materials with COFs or combining COFs with metal organic framework derived carbon/metal composites.
