Abstract Aqueous Zn metal batteries (AZMBs) have appealing advantages, including good safety, low cost, and high volumetric energy density. However, serious parasitic reactions dendrite growth at anodes hinder practical applications of AZMBs. Here, a nature‐inspired strategy is proposed to improve using plant‐cell derivatives as additives for ZnSO 4 electrolytes. In the electrolyte, TEMPO (2,2,6,6‐tetramethylpiperidine‐1‐oxyl)‐oxidized cellulose nanofibers (TOCN) calcium lignosulfonate (CL) with specific functional groups modulate 2+ solvation structure. More importantly, they reform cell membrane/wall‐like layer mechanical strength selective transmission/plating on anode surface, which enables uniform deposition alleviates side reactions. As result, symmetric cells dual‐additive electrolyte exhibit highly reversible dendrite‐free stripping/plating behavior over 2000 500 h 2 mA cm −2 /1 mAh 10 /10 , respectively. Furthermore, Zn//NH V O full shows cycling stability 300 cycles negative/positive (N/P) ratio. A density 92.9 Wh kg −1 can be delivered limited metallic consumption, showing that has prospects use.

Abstract Aqueous Zn‐ion batteries (AZIBs) recently have attracted broad attention. To achieve high energy density of AZIBs, constructing high‐loading cathodes is the prerequisite. However, cycling stability still faces great challenges. Herein, a comprehensive strategy proposed to improve structural cathode material and mechanical cathode. The BiOBr@BiOIO 3 heterostructure are successfully constructed via sharing interfacial oxygen atoms, in which effect can effectively enhance reaction dynamics stability. Meanwhile, biomimetic binder skillfully designed situ dual cross‐linking between guar gum cation ions application water‐based sustainable polymer AZIBs. Density functional theory calculations demonstrate possesses strong affinity toward firmly adhere active materials. Quantitative nanomechanic technology visually demonstrates robust properties as‐obtained As result, when loading increases as 100.71 mg cm −2 , an ultrahigh areal capacity 20.02 mAh be achieved. Specially, quasi‐Ah‐level (0.244 Ah) pouch‐type cell with 1.17 g constructed, showing practical potential.

Abstract Flexible Zn‐ion batteries (ZIBs) have been regarded as a promising energy storage solution for flexible electronics. However, the challenges of dendrite growth due to uneven current density distribution and limited anode flexibility impeded their practical application. Herein, 3D zinc with dual gradient in porosity conductivity is presented. This dual‐gradient nanofibrous exhibits exceptional durability, showing less than 10% change resistance after 15 000 bending cycles. The vertical promotes preferential deposition at bottom section, while facilitates Zn 2 ⁺ ion migration ensures timely replenishment inner space membrane. combination structure design fosters bottom‐up deposition, effectively preventing formation. Symmetric cells this demonstrate outstanding cycling stability, maintaining more 410 h operation 1 mA cm −2 , surpassing reference samples most previously reported anodes. quasi‐solid‐state ZIBs assembled exhibit excellent stability under various mechanical deformations. These anodes designs hold great promise advancing application batteries.
