Опубликована: Окт. 16, 2023

Abstract Side reactions on zinc metal (Zn) anodes are formidable issues that cause limited battery life of aqueous zinc‐ion batteries (AZIBs). Here, a facile and controllable layer‐by‐layer (LbL) self‐assembly technique is deployed to construct an ion‐conductive mechanically robust electrolyte/anode interface for stabilizing the Zn anode. The LbL film consists two natural biodegradable bio‐macromolecules, chitosan (CS) sodium alginate (SA). It shown such tailors solvation sheath ions facilitates oriented deposition Zn. Symmetric cells with four double layers CS/SA ((CS/SA) 4 –Zn) exhibit stable cycles over 6500 h. (CS/SA) –Zn||H 2 V 3 O 8 coin cell maintains specific capacity 125.5 mAh g −1 after 14 000 cycles. pouch electrode area 5 × 7 cm also presents retention 83% 500 at 0.1 A . No obvious dendrites observed long in both symmetric full cells.

Abstract Texturing metallic zinc anodes (MZAs) for selective exposure of (002) Zn plane with high thermodynamical stability is an efficient scheme dendrite‐free electrodeposition. However, fundamental factors that influence deposition morphology via surface crystallographic texture engineering are not well understood. Herein, different from traditional cognition, MZAs preferential (101) facet demonstrated to be equally effective in promoting deposition, which enabled by introducing trace amount (0.01 m ) theophylline into ZnSO 4 electrolyte. Experimental results and mathematical model corroborate, indicating mechanistically the derived cations preferentially adsorb on crystal due higher adsorption energy, thereby accelerating its growth through increased binding affinity 2+ ions. Consequently, this phenomenon facilitates achieve ordered orientation (101‐Zn), thus enabling electrodeposition/dissolution cycling over 650 h under a depth discharge up 40% significantly boosting rechargeability (76.7% capacity retention after 1000 cycles) 101‐Zn||carbon‐cloth@MnO 2 full battery relative counterpart without additive (36.3%). The work offers deep insights scientific links between morphology, while opens vast untapped opportunities realize MZAs.

Опубликована: Авг. 18, 2023

Abstract Zn powder‐based anodes are promising for flexible Zn‐ion batteries with large‐scale production, but the drawbacks such as dendrite growth and side reactions strictly hinder their wide application. Herein, a free‐standing anode gradient particle size porosity is facilely constructed batteries. The design not only optimizes electric field distribution flux also induces ideal bottom‐up deposition top‐down stripping behaviors of Zn, thus suppressing growth. As result, powder can be stably cycled 1250 h at 1 mA cm −2 /1 mAh , even high current/capacity 5 /5 it still achieves long lifespan 130 h, which outperforms its non‐gradient counterparts most previous results from anodes. strategy expected to inspire extensive utilization energy storage devices.
