“…As shown in Figure 1d, the characteristic stretching vibrations associated with the C═N (1629 cm −1 ), C–N (1366/1224 cm −1 ), and C═C (1536 cm −1 ) can be attributed to the phenazine and aromatic rings, respectively. [ 44,49 ] These are well consistent with the characteristic groups in DAP monomer, indicating the successful polymerization of DAP and formation of PDAP.…”

Achieving reversible insertion/extraction in most cathodes for aqueous aluminum ion batteries (AAIBs) is a significant challenge due to the high charge density of Al3+ and strong electrostatic interactions. Organic materials facilitate the hosting of multivalent carriers and rapid ions diffusion through the rearrangement of chemical bonds. Here, a bipolar conjugated poly(2,3‐diaminophenazine) (PDAP) on carbon substrates prepared via a straightforward electropolymerization method was introduced as cathode for AAIBs. The integration of n‐type and p‐type active units endow PDAP with an increased number of sites for ions interaction. The long‐range conjugated skeleton enhances electron delocalization and collaborates with carbon to ensure high conductivity. Moreover, the strong intermolecular interactions including π−π interaction and hydrogen bonding significantly enhance its stability. Consequently, the Al//PDAP battery exhibits a large capacity of 338 mAh g−1 with long lifespan and high‐rate capability. It consistently demonstrates exceptional electrochemical performances even under extreme conditions with capacities of 155 and 348 mAh g−1 at −20 and 45 °C, respectively. In/ex situ spectroscopy comprehensively elucidates its cation/anion (Al3+/H3O+ and ClO4−) storage with 3‐electron transfer in dual electroactive centers (C = N and ‐NH‐). This study presents a promising strategy for constructing high‐performance organic cathode for AAIBs over a wide temperature range.This article is protected by copyright. All rights reserved

“…For the past few years, Aqueous Zinc Ion Batteries (AZIBs) have undergone continuous development owing to the advantages of cost effectiveness, high safety and eco-friendliness of AZIBs [3], and therefore have enormous development potential in the field of energy storage applications. At present, investigation of AZIBs cathode materials has focused on Prussian blue analogues, manganese-based materials, vanadium-based materials, organic materials, as well as transition metal sulphides, etc., [4][5][6][7][8]. China has abundant vanadium ore resources, while vanadium has a variety of valence states and rich chemical structure properties conducive to making vanadium-based materials with high energy storage capacity and to becoming AZIB cathode material with great application potential.…”

Rechargeable aqueous zinc-ion batteries have attracted a lot of attention owing to their cost effectiveness and plentiful resources, but less research has been conducted on the aspect of high volumetric energy density, which is crucial to the space available for the batteries in practical applications. In this work, highly crystalline V2O5 microspheres were self-assembled from one-dimensional V2O5 nanorod structures by a template-free solvothermal method, which were used as cathode materials for zinc-ion batteries with high performance, enabling fast ion transport, outstanding cycle stability and excellent rate capability, as well as a significant increase in tap density. Specifically, the V2O5 microspheres achieve a reversible specific capacity of 414.7 mAh g−1 at 0.1 A g−1, and show a long-term cycling stability retaining 76.5% after 3000 cycles at 2 A g−1. This work provides an efficient route for the synthesis of three-dimensional materials with stable structures, excellent electrochemical performance and high tap density.

“…33,34 Organic electrode materials are mainly composed of sustainable elements, for example, C, H, and O, and can be derived from readily available biomass resources. 35–38 Moreover, organic electrode materials offer great design flexibility, enabling the customization of physical properties and electrochemical performance. 39–41 In addition, in organic materials for AZIBs, the redox reaction primarily involves the rearrangement of chemical bonds rather than the insertion or extraction of Zn 2+ , thus mitigating the extensive structural changes commonly observed in inorganic compounds.…”
