Abstract Aqueous zinc ion batteries (AZIBs) are promising for large‐scale energy storage due to the advantages of high safety, theoretical capacity, and cost‐effectiveness. However, stability AZIBs is poor (generally 50–100 cycles) at low current densities side reactions. Here, choline glycerophosphate (CGP) introduced as a zwitterion additive improve performance AZIBs. The CGP helps form new solvated structure Zn 2+ , named zwitterion‐separated pair (ZSIP) that can link OTf − repel H 2 O molecular.

Abstract MXene‐based Zn‐ion capacitors (ZICs) with adsorption‐type and battery‐type electrodes demonstrate high energy storage anti‐self‐discharge capabilities, potentially being paired triboelectric nanogenerators (TENGs) to construct self‐powered systems. Nevertheless, inadequate interlayer spacing, deficient active sites, compact self‐restacking of MXene flakes pose hurdles for ZICs, limiting their applications. Herein, black phosphorus (BP)‐Zn‐MXene hybrid is formulated ZIC via a two‐step molecular engineering strategy pre‐intercalation BP nanosheet assembly. Zn ions as intercalators induce cross‐linking expandable spacing serve scaffolds nanosheets, thereby providing sufficient accessible sites efficient migration routes enhanced storage. The density functional theory calculations affirm that zinc adsorption diffusion kinetics are significantly improved in the hybrid.

Abstract The rechargeable aqueous ammonium ion battery shows great potential in low‐cost energy storage system because of its long life and environmental friendliness. However, most inorganic host materials used batteries are still limited by slow diffusion kinetics. Herein, it is identified that a 2D heteroligand‐based copper‐organic framework featuring numerous adsorption site the π‐conjugated periodic skeleton supplies multiple accessible redox‐active sites for high‐performance storage. Benefitting from effective regulation electron delocalization heteroligand inherent hydrogen bond cage mechanism between ions, resultant full delivers large specific density 211.84 Wh kg −1 , can be stably operated 12000 cycles at 5 A g over 80 days.

Abstract Multiple redox‐active amphoteric organics with more n‐p fused electron transfer is an ongoing pursuit for superior zinc–organic batteries (ZOBs). Here we report multi‐heterocycle‐site donor‐acceptor conjugated organic superstructures (AOSs) by integrating three‐electron‐accepting n‐type triazine motifs and dual‐electron‐donating p‐type piperazine units via H‐bonding π–π stacking. AOSs expose flower‐shaped N‐heteromacrocyclic delocalization topologies to promise full accessibility of built‐in ultralow activation energy, thus liberating capacity (465 mAh g −1 ) Zn||AOSs battery. More importantly, the extended multiple donor‐acceptor‐fused feature satisfied discharge voltage anti‐dissolution in electrolytes, pushing both energy density cycle life ZOBs a new level (412 Wh kg 70,000 cycles@10 A ).

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.

VOPO4·2H2O (VOP) has attracted significant attention as a cathode material for aqueous zinc-ion batteries owing to its layered structure and high-voltage plateau. However, application is hindered by sluggish Zn2+ transport kinetics instability in electrolytes, leading rapid capacity fading over cycling. In the present work, diethylene glycol (DEG) pre-intercalated VOP (DEG-VOP) with flower-like morphology prepared facile hydrothermal method. The DEG molecules enlarge interplanar lattice of (001) plane introduce oxygen vacancies, accelerating mass charge transfer kinetics. addition, pre-intercalation induces self-assembly nanosheets into structure, which exposes more (201) planes, providing additional ion channels. also enhances hydrophobicity VOP, effectively suppressing decomposition dissolution. These result significantly improved discharge capacity, retention 86% after 2000 cycles at 1 A g–1.
