　　Lithium-ion batteries, as a high-performance energy storage device, have been widely used in various mobile power sources and other renewable clean energy carriers, and a new generation of lithium-ion batteries with high energy density and power density has attracted increasing attention. In order to further improve the performance of lithium-ion batteries, Professor Yong Wang and Associate Professor Sun Weiwei’s research group conducted research on the application of environmentally friendly and renewable organic electrode materials in lithium-ion batteries, and constructed a two-dimensional co-existence with a small number of layers through molecular-level design. Conjugated covalent organic frame electrode materials greatly improve the lithium storage performance of organic electrodes, and the reversible lithium storage capacity can be as high as 1500mAh/g, which is not inferior to high-capacity inorganic electrode materials.

　　This research achievement has realized the full excitation and utilization of the active lithium storage sites between the layers or the internal structure of the organic framework material, thereby obtaining an organic electrode material for lithium-ion batteries with ultra-high reversible lithium storage capacity and excellent cycle stability. At the same time, through the in-depth study of the staged lithium storage mechanism, it provides a certain theoretical support and guidance for the design, synthesis, derivative modification and further application of organic frame electrode materials.
