Summary: Covalent organic frameworks (COFs) have gained attention as promising cathode materials for Li-ion batteries. However, the capacity of COF electrodes reported so far is still unsatisfactory. In this study, a new two-dimensional polyimide-linked COF, HATN-AQ-COF, was designed and fabricated. It possesses multiple redox-active sites for Li+ ion storage, excellent stability, good conductivity, and a large pore size. The HATN-AQ-COF electrode demonstrates a high reversible capacity, active site utilization, and cycle performance, making it one of the best performers among reported COF electrodes.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
