Rechargeable magnesium batteries have the potential for large-scale energy-storage applications, but traditional inorganic cathodes suffer from inferior performance and insufficient selections. Organic conjugated carbonyl compounds are promising cathode materials with a delocalized negative charge, reversible enolization, wide designability. Herein, sulfur heterocyclic quinones of dibenzo[b,i]thianthrene-5,7,12,14-tetraone (DTT) benzo[b]naphtho[2′,3′:5,6][1,4]dithiino[2,3-i]thianthrene-5,7,9,14,16,18-hexone (BNDTH) prepared investigated as rechargeable compared normal quinone 5,7,12,14-pentacenetetrone (PT). DTT BNDTH show higher redox potentials, storage capacities, better cycling stabilities than PT. Mechanism study theoretical computation reveal that adjacent carbonyls connected atoms in coordinate bivalent cations rigid PT via conformation change, leading to reaction reversibility. lower LUMO energy levels thus potentials solubilities electrolytes result stability. The comparative herein would provide scientific insights into rational design organic suitable stable reactions cations.

Abstract Organic polymer materials have attracted much attention in rechargeable aqueous magnesium ion batteries (AMIBs) due to their sustainability and structural designability. However, the ionic storage capability is hindered by insufficient redox‐active sites, dissolvability electrolytes, short‐range conjugated structures, resulting low energy density poor cycling stability. Herein, a sulfur‐heterocyclic aromatic polyimide‐based organic (PTDBS) constructed with multiple sites long‐range conjugate, which employed as active material for AMIB anode, achieving an outstanding Mg 2+ capability. Benefitting from introduced thioether bonds, PTDBS possesses enhanced electronic conductivity additional reversible coordination, thus ensuring high redox activity superior electron affinity. As result, electrode delivers ultrafast stable MgCl 2 electrolyte rate capacity of 98.6 mA h g −1 at 10.0 A , remarkable stability over 7500 cycles retention 90.0%. Notably, all‐organic full cell, realized coupling anode polyindole cathode, achieves long lifespan. This work lays foundation development highly large‐scale storage.

Abstract Renewable energy‐powered seawater electrolysis is a green and attractive technique for producing high‐purity hydrogen. However, severe chlorideions (Cl − ) their derivatives tend to corrode anodic catalysts at ampere‐level current densities hinder the application of seawater‐to‐H 2 systems. Herein, polycalmagite (PCM)‐coated NiFe layered double hydroxide presented on Ni foam (NiFe LDH@PCM/NF) that exhibits exceptional stability in alkaline seawater. PCM not only acts as conductive layer reduce charge transfer resistance anodes but also polymer‐based protective inhibit Cl adsorption stabilize metal ions oxidation due its own anions strong adhesion, thereby increasing activity during Thus, LDH@PCM/NF needs low overpotential 364 mV reach up 1000 mA cm −2 maintains operation 500 h without degradation. Moreover, minimal amount hypochlorite can be detected electrolyte after 500‐h test. This development affords significant exploration creating durable efficient anodes, highlighting importance polymer coating toward anti‐corrosion oxidation.

Abstract Rechargeable magnesium batteries (RMBs) are emerging as a safer, high‐capacity alternative to lithium‐ion due the high volumetric capacity and reduced dendrite formation of anode. Among different cathodes RMBs, bipolar‐type materials further enhance energy density RMBs by balancing redox potential with specific capacity. Herein, application emeraldine base polyaniline (PANI) cathode material for is explored. PANI exhibits both p ‐ n ‐type charge storage behaviors, enabling 186.8 mAh g −1 stable cycling performance at current 200 mA power 6341.8 W kg superior traditional materials. First principle calculations ex situ characterizations reveal that molecular structure supports bipolar mechanism. Additionally, pouch cells based on demonstrate reliable operation flexibility, positioning promising advanced other systems.
