Abstract Lithium‐ion batteries (LIBs), known for their high energy density and long cycle life, have become indispensable in everyday applications. Unfortunately, the increasing demand LIBs raises concerns about sustainability of lithium resources. Non‐lithium metal‐ion therefore garnered significant attention due to abundant resources potential cost advantages. Yet, widespread adoption is hindered by limited availability high‐performance cathode materials. Organic electrode materials (OEMs) emerged as promising candidates, owing structural diversity tunability, allowing them accommodate large cations. Despite potential, most OEMs suffer from unsatisfactory cyclability, poor rate performance, low density. This review summarizes recent advancements improving electrochemical performance OEMs, focusing on molecular engineering approaches mitigate dissolution, enhance conductivity The charge storage mechanism current challenges associated with are first discussed. Various strategies designed address these then explored, including linkage improve stability electronic Finally, insights provided future development next‐generation battery technologies beyond LIBs.

Abstract Covalent organic framework (COF) membranes feature with well‐developed 1D in‐plane pores and parallelly arranged 2D interlayer gallery, presenting promising platform for precise separations. However, it remains a formidable challenge to construct regulate membrane channels at angstrom scale. Herein, pH‐sensitive dopamine is taken advantage elaborately engineer the spatial size of 1D/2D in COF separations alkali metal ions. Acid treatment allows monomolecular segment membrane, achieving ultramicroporous regulation from 1.25 nm 0.71 nm, which enables high selectivity 18.7 K + /Li separation. Molecular dynamics simulations reveal higher dehydration degree, weaker channel‐cation interaction faster diffusion coefficient than Li . For alkaline treatment, self‐polymerizes form nanoparticles between layers, enlarges 0.33 0.45 enabling high‐permeance ion/molecule The water permeance increases 86.7% 404 L m −2 h −1 bar , without sacrifice sieving ability. Both cation separation performances outperform current state‐of‐the‐art membranes. This dopamine‐mediated channel engineering strategy may provide new insights design

Abstract The advancement of nanofluidic membranes is critical for mimicking bioelectrogenic ion‐channel mechanisms and boosting output power density, essential sustainable energy applications. conversion efficiency these devices significantly relies on the ion conductivity permselectivity membranes. Membranes with aligned one‐dimentional (1D) pores, high pore organized dangling ionic groups are theorized to offer superior permeability selectivity, yet configurations remain underexplored. Herein, successful fabrication oriented covalent organic framework (COF) presented. These exhibit precisely cationic anionic sites within their channels, achieved through post‐synthetic modification using click chemistry, which shows conductivity. When incorporated into full‐cell thermo‐osmotic generators, deliver an impressive density 195 W m −2 under a 50‐fold salinity gradient (NaCl: 0.01 ‖ 0.5 ) along 35 K temperature differential. This substantially increases 2.41 times 471 −2 when enhanced tenfold, surpassing performance existing similar conditions thus offering promising avenue enhancing in resource utilization.
