Abstract 2D π‐d conjugated metal–organic frameworks ( c ‐MOFs) are promising anode candidates for sodium‐ion batteries (SIBs) due to their high intrinsic conductivity and stability in organic electrolytes. However, the development of ‐MOFs with multi‐redox sites improve overall performance SIBs is highly desired but remains a great challenge. Herein, this work reports electrochemically active hexaazatrinaphthylene‐based (HATN‐XCu, X = O or S) as advanced materials dual‐redox SIBs. The...
The uncontrolled zinc electrodeposition and side reactions severely limit the power density lifespan of Zn metal batteries. Herein, multi-level interface adjustment effect is realized with low-concentration redox-electrolytes (0.2 m KI) additives. iodide ions adsorbed on surface significantly suppress water-induced by-product formation enhance kinetics deposition. distribution relaxation times results reveal that can reduce desolvation energy hydrated guide deposition due to their strong...
Nitrogen‐rich porous carbons (NPCs) are the leading cathode materials for next‐generation Zn–air and Li–S batteries. However, most existing NPC suffers from insufficient exposure harnessing of nitrogen‐dopants (NDs), constraining electrochemical performance. Herein, by combining silica templating with in situ texturing metal–organic frameworks, a new bifunctional 3D nitrogen‐rich carbon photonic crystal architecture simultaneously record‐high total pore volume (13.42 cm 3 g −1 ), ultralarge...
Abstract An in situ strategy to simultaneously boost oxygen reduction and evolution (ORR/OER) activities of commercial carbon textiles is reported the direct use such ubiquitous raw material as low‐cost, efficient, robust, self‐supporting, bifunctional air electrodes rechargeable Zn‐air batteries demonstrated. This not only furnishes with a large surface area hierarchical meso‐microporosity, but also enables efficient dual‐doping N S into skeletons while retaining high conductivity stable...
Aqueous zinc (Zn) ion batteries with low cost and high safety are promising devices for grid energy storage; however, the Zn anode problems, including dendrite growth parasitic side reactions, severely retard their practical implementation. Here, a two-dimensional covalent-organic framework (COF) coating is developed to address these issues. Under regulation of an optimal modulator, prepared COF (COF–H) containing rich alkynyl units in AA-stacking mode not only features flower-like structure...
Abstract Aqueous zinc ion batteries (ZIBs) hold great promise for large‐scale energy storage; however, severe dendritic growth and side reactions on the anode dramatically impede their commercial application. Herein, a Zr‐based MOF (UiO‐66) functionalized with high density of sulfonic acid (─SO 3 H) groups is used to modify glass fiber (GF) separator ZIBs, providing unique solution stabilizing Zn anode. Benefiting from strong interaction between zincophilic −SO H 2+ , this sulfonate‐rich...
The solubility behaviour of polysulfides in electrolyte solutions is a major bottleneck prior to the practical application lithium–sulfur battery. To address this issue, we fabricate tannic acid/FeIII complex-coated polypropylene (PP) separator (TA/FeIII-PP separator) via simple, fast, and green method. Benefiting from dual-confinement effects based on Lewis acid–base interactions between FeIII as well dipole–dipole rich phenol groups polysulfides, migration effectively suppressed....
C2N has emerged as a new family of promising two-dimensional (2D) layered frameworks in both fundamental studies and potential applications. Transforming bulk into zero-dimensional quantum dots (QDs) could induce unique confinement edge effects that produce improved or properties. Despite their appealing potential, C2NQDs remain unexplored, intriguing properties understanding prominent are still not well understood. Here, we report the first synthesis water-soluble via top-down approach...

Lithium–sulfur (Li–S) batteries hold great promise for new-generation energy storage technologies owing to their overwhelming density. However, the poor conductivity of active sulfur and shuttle effect limit widespread use. Herein, a carbon cloth decorated with thiol-containing UiO-66 nanoparticles (CC@UiO-66(SH)2) was developed substitute traditional interlayer current collector Li–S batteries. One side CC@UiO-66(SH)2 acts as load materials, while other serves an further restrain...
Conjugated microporous polymers (CMPs) with porous structure and rich polar units are favorable for high-performance lithium-sulfur (Li-S) batteries. However, understanding the role of building blocks in polysulfide catalytic conversion is still limited. In this work, two triazine-based CMPs constructed by electron-accepting triazine electron-donating triphenylbenzene (CMP-B) or triphenyltriazine (CMP-T), which can grow on a conductive carbon nanotube (CNT) to serve as separator modifiers...
We apply a versatile reaction to solid: the former involves electron-deficient alkene tetracyanoethylene (TCNE) as guest reactant; latter consists of stacked 2D honeycomb covalent networks based on electron-rich β-ketoenamine hinges that also activate conjugated, connecting alkyne units. The TCNE/alkyne is [2 + 2] cycloaddition–retroelectrocyclization (CA-RE) forms strong push–pull units directly into backbone framework─i.e., using only minimalist "bare-bones" scaffold, without need for...
