The architecture of anode materials is an essential factor in improving the performance of energy storage devices, which meets the increasing demand for energy storage and helps achieve environmental sustainability targets. Atomic manufacturing allows the makeup of electrodes to be changed precisely at the atomic level. This facilitates the creation of electrode materials with specific physical properties and enhanced performance. This Perspective reviews the details of how the microstructure design influences key electrode material characteristics. Finally, we anticipate the potential of materials and manufacturing techniques for materials microstructure in the future. A thorough grasp of the materials microstructure in electrode materials is offered by this article.

Lithium–Sulfur batteries (LSBs) are widely regarded as one of the most promising energy storage systems due to their ultra‐high theoretical energy density and environmental friendliness. However, practical applications of LSBs face significant challenges, including the shuttle effect of soluble polysulfides and the formation of lithium dendrites. Covalent organic frameworks (COFs) have emerged as potential materials for inhibiting the polysulfide shuttle effect and buffering lithium dendrites. This review provides an overview of the latest advancements in the use of COF and its derivative materials as sulfur host materials, modified commercial separators, and electrolytes in LBSs, and makes some brief conclusions and predictions. Pure COFs, COF derivatives, and COF composites are discussed as sulfur hosts, along with novel strategies intended to enhance LSB cycling stability and reversibility. Strategies for enhancing LSBs performance are summarized through the modification of separators using COFs, with the ultimate goal of achieving high energy density. It also discusses the strategies for designing COF‐based electrolytes, which include structural design, use of ionic COFs, and introduction of lithium salt molecules or flexible oligo(ethylene oxide) chains into COF skeletons. Additionally, the review discusses some future prospects for the use of COFs and their derivatives in LSBs.
