However, they still suffer from sluggish redox kinetics and the shuttle effect caused by complex polysulfides. In this work, graphitic carbon nitride (g-C<sub>3</sub>N<sub>4</sub>) is utilized as a template and further hydrothermally treated with an Mn source and glucose. The pyrolysis of g-C<sub>3</sub>N<sub>4</sub> gives rise to N-doped carbon nanotubes, producing abundant sites for physical confinement and chemical adsorption of polysulfides, while glucose carbonization brings forth amorphous carbon and Mn source produces metal spheres. Afterward, polydopamine (PDA) induces N-doped carbon coating and promotes interface connection as well as electron immigration. This synergistic design possesses a high surface area of micropores and mesopores to aggregate sulfur and accelerate redox kinetics. As a result, the N-doped carbon nanotube with Mn spheres and PDA coating@sulfur (CN/Mn-PDA@S) exhibits a high reversible capacity of 813.5 mAh g<sup>−1</sup> at 1 C with a decay rate of 0.064% per cycle and remarkable capacity retention at 2 C with rate performance up to 4 C.

One of the important reasons is the drastic fluctuation in the concentration of Zn<sup>2+</sup> ions on the electrode surface during the charging and discharging process. In this work, an electrolyte with Zn<sup>2+</sup> ion buffer layer (EZIBL) is proposed to regulate the ZEDP. First, numerical simulations and corresponding experiments are conducted to assess the impact of different thicknesses of the Zn<sup>2+</sup> ion buffer layer (ZIBL) on the variation in Zn<sup>2+</sup> ion concentration, from which the optimal thickness of the ZIBL is determined. Then, the regulation role of EZIBL in the cycling process is demonstrated by a Zn-Cu half cell. Further, combined with the potential profile of the symmetric cell and the experimental phenomena, the regulation role of EZIBL in ZEDP is systematically explained at the mechanistic level through the analysis of key parameters. Finally, a full battery composed of Zn-LiMn<sub>2</sub>O<sub>4</sub> is assembled to evaluate the practical applicability of the EZIBL in real battery cycles, which shows great enhancement in capacity retention and coulombic efficiency. This work proposes the design of the EZIBL used to regulate the ZEDP and provides a simple, low-cost regulation method for the development of high-performance AZBs.</div></div>","PeriodicalId":61638,"journal":{"name":"材料导报:能源(英文)","volume":"4 4","pages":"Article 100292"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142747836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By varying pulse durations, we were able to exert precise control over Au NP size and distribution without stabilizing agents. Characterization using field emission scanning electron microscopy and X-ray diffraction techniques confirmed the formation of clustered nanoparticles of metallic gold phase. Electrochemical characteristics analyses revealed that Au NPs synthesized with a 900 ms pulse duration exhibited the lowest charge transfer resistance and the highest electrochemically active surface area. The electrocatalytic performance test of these Au NPs demonstrated an anodic current density of 2.5 mA cm<sup>−2</sup> and a Tafel slope of 78 mV dec<sup>−1</sup>, indicating superior catalytic performance and reaction kinetics. Additionally, the Au NPs showed high resistance to poisoning, as evidenced by a low <em>j</em><sub>b</sub>/<em>j</em><sub>f</sub> ratio of 0.28 and stable chronoamperometric response.
