Rampant dendrite growth and severe parasitic reactions at the electrode/electrolyte interface significantly limit cycle life of aqueous zinc ion hybrid supercapacitors (ZHSCs). In this study, sodium lignosulfonate (SLS) as one green polymer was introduced into ZnSO4 electrolyte to construct a multifunctional layer on surface Zn plates. Experimental analyses theoretical calculations show that presence SLS layer, rich in oxygen-containing functional groups (-SO3-), can not only modulate structure electric double (EDL) suppress interfacial side caused by free H2O SO42-, but also promote (101)-oriented deposition selectively controlling behavior Zn2+ through specific adsorption different crystalline surfaces. The optimized allows stable Zn//Zn symmetric cells achieve cumulative plating capacity exceeding 4 Ah cm-2 high areal 5 mAh cm-2, cycling for more than 1000 cycles with an excellent average Coulombic efficiency 99.34% Zn//Cu asymmetric cells. Zn//AC ZHSC exhibits ultralong stability over 40,000 electrolyte, decay rate low 0.000285% per cycle.

Porosity and Conductivity Dual‐Gradient Design on Ultrathin 3D Nanofibrous Anode for Flexible Zn‐Ion Batteries

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Март 16, 2025

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.

Abstract Zn metal is considered a promising anode for aqueous zinc ion batteries (AZIBs) owing to its high capacity and cost‐effectiveness. However, dendrite growth, corrosion, hydrogen evolution occurring on the surface pose significant challenges achieving stable reliable AZIBs. Herein, robust organic–inorganic protective layer, comprising organic alginate (ZA) inorganic Ti 3 C 2 T x MXene, fabricated via simple blade‐coating approach. The ZA MXene synergistically complement each other, with playing crucial role in inhibiting enhancing electrolyte affinity, while mitigates severe side reactions, enables uniform 2+ deposition, accelerates electron/ion transfer. Consequently, ZA/MXene layer (MXZA) facilitates exhibit remarkable reversibility stability during continuous plating/stripping, long‐term lifespan of 2500 h at mA cm −2 mAh , 360 even 50 symmetric cells. When configurated sodium vanadate (NVO) cathode, MXZA@Zn||NVO full cell operates stably high‐capacity retention 98.4% over 1000 cycles. This work provides new perspective developing efficient surface/interface modifications synergistic effects toward high‐performance anodes.
