Emerging rechargeable aluminium batteries (RABs) offer a sustainable option for next-generation energy storage technologies with low cost and exemplary safety. However, the development of RABs is restricted by limited availability high-performance cathode materials. Herein, we report two polyimide two-dimensional covalent organic frameworks (2D-COFs) cathodes redox-bipolar capability in RAB. The optimal 2D-COF electrode achieves high specific capacity 132 mAh g-1 . Notably, presents...
The anion-intercalation chemistries of graphite have the potential to construct batteries with promising energy and power breakthroughs. Here, we report use an ultrathin, positively charged two-dimensional poly(pyridinium salt) membrane (C2DP) as electrode skin overcome critical durability problem. Large-area C2DP enables conformal coating on electrode, remarkably alleviating electrolyte. Meanwhile, dense face-on oriented single crystals ultrathin thickness cationic backbones allow high...
Abstract The pressing demand for sustainable energy storage solutions has spurred the burgeoning development of aqueous zinc batteries. However, kinetics-sluggish Zn 2+ as dominant charge carriers in cathodes leads to suboptimal charge-storage capacity and durability Here, we discover that an ultrathin two-dimensional polyimine membrane, featured by dual ion-transport nanochannels rich proton-conduction groups, facilitates rapid selective proton passing. Subsequently, a distinctive...
Abstract Magnesium (Mg) batteries hold promise as a large‐scale energy storage solution, but their progress has been hindered by the lack of high‐performance cathodes.

Specifically, classic magnesium aluminum chloride complex (MACC) electrolyte is tailored introducing Mg bis(trifluoromethanesulfonyl)imide (Mg(TFSI) 2 ), which...
Abstract Vinylene‐linked two‐dimensional polymers (V‐2DPs) and their layer‐stacked covalent organic frameworks (V‐2D COFs) featuring high in‐plane π‐conjugation robust have emerged as promising candidates for energy‐related applications. However, current synthetic approaches are restricted to producing V‐2D COF powders that lack processability, impeding integration into devices, particularly within membrane technologies reliant upon thin films. Herein, we report the novel on‐water surface...
Abstract Constructing dual‐ion energy storage devices using anion‐intercalation graphite cathodes offers the unique opportunity to simultaneously achieve high density and output power density. However, a critical challenge remains in lack of proper anodes that match with cathodes, particularly sustainable electrolyte systems abundant potassium.

Charge transport through a randomly oriented multilayered network of two-dimensional (2D) Ti3C2Tx (where Tx is the surface termination and corresponds to O, OH F) was studied using time-of-flight photoconductivity (TOFP) method, which highly sensitive distribution charge carrier velocities. We prepared samples comprising with thickness 12 nm or 6-monolayers. MXene flakes size up 16 μm were deposited on by spin-coating from water solution. Using TOFP, we have measured electron mobility that...
Graphite-based dual-ion batteries (GDIBs) represent a promising battery concept for large-scale energy storage on account of low cost, high working voltage, and sustainability. The electrolyte concentration plays critical role in determining the density cycle life GDIBs. However, concentrated electrolytes show Lithium ions (Li+) transport kinetics, reducing their intercalation solid interface (SEI) formation abilities. Moreover, GDIBs cut-off voltage suffer from degradation, corrosion...
