Zinc (Zn) metal anode suffers from uncontrollable Zn dendrites and parasitic side reactions at the interface, which restrict practical application of aqueous rechargeable zinc batteries (ARZBs). Herein, an amphoteric cellulose-based double-network is introduced as hydrogel electrolyte to overcome these obstacles. On one hand, groups build anion/cation transport channels regulate electro-deposition behavior on (002) crystal plane enabled by homogenizing Zn2+ ions flux. other strong bonding...

Aqueous rechargeable Zn-metal batteries (ARZBs) are considered one of the most promising candidates for grid-scale energy storage. However, their widespread commercial application is largely plagued by three major challenges: The uncontrollable Zn dendrites, notorious parasitic side reactions, and sluggish
Although organic cathode materials with sustainability and structural designability have great potential for rechargeable lithium batteries, the dissolution issue presents a huge challenge to meet demands of cycling stability energy density simultaneously. Herein, we designed successfully synthesized two novel small-molecule (SMOCMs) by same innovative route, namely 7,14-diazabenzo[a]tetracene-5,6,8,13-tetraone (DABTTO) 7,9,16,18-tetraazadibenzo[a,l]pentacene-5,6,8,14,15,17-hexaone...
Abstract Organic cathode materials (OCMs) possess high resource sustainability, large structural diversity, theoretical energy density, and potentially low cost, however, suffer from the dissolution problem in liquid non‐aqueous electrolyte. Solid‐state batteries (SSBs) are regarded as final solution of Li Na metal because intrinsic safety, but hindered by many challenges including poor contact with rigid inorganic materials. Therefore, applying OCMs SSBs is probably a win‐win strategy to...
Rechargeable magnesium batteries (RMBs) are one of the most promising "post-lithium" battery technologies, but electrochemical performance is still far from expectation due to sluggish reaction kinetics divalent Mg
Aqueous zinc batteries (AZBs) are considered one of the most promising candidates for grid-scale energy storage. However, achieving a stable electrode-electrolyte interface remains challenge developing high-performance AZBs. Herein, taking Zn||phenazine (PNZ) system as prototype, where proton uptake/removal mechanism dominates in cathode, carboxylic acid-functionalized cellulose hydrogel electrolyte is designed to simultaneously solve issues at both anode and cathode interfaces....
Abstract Sustainable and structurally designable organic cathode materials hold immense promise for rechargeable lithium batteries, yet the dissolution issue poses a significant challenge to their cycling stability. For small‐molecule (SMOCMs), extending π‐conjugated system is an effective method mitigate dissolution, however, remains huge if requiring high energy density affordable synthesis concurrently. Herein, novel quinone‐based SMOCM successfully synthesized though straightforward...
The growth of Zn dendrites and interfacial side reactions are two critical challenges impeding the commercial application aqueous zinc batteries (AZBs). amphoteric electrolyte additive is considered a convenient efficient strategy to stabilize anode. However, most studies overlook impacts their charge compositions corresponding mechanisms on Zn2+ electroplating behavior. Here, we use cellulose as an exemplary research object, number positive/negative groups can be easily effectively...
Abstract Organic cathode materials (OCMs) have been widely applied in aqueous rechargeable zinc batteries (ARZBs), but there are still many novel structures to be explored for better electrochemical performance and clearer mechanism. Herein, we studied an organic biological dye, namely thionin (Thn‐CH 3 COO), as a bipolar‐type OCM ARZBs based on its electroactive phenothiazine unit. In the optimal electrolyte of 2 M Zn(CF SO ) , Thn‐CH COO exhibited lowest solubility thus highest cycling...

Based on it, successfully synthesized three 1,4-diazaanthraquinone (DAAQ) dimers,...
