In particular, the aqueous zinc-ion battery (AZIB) has been regarded as a promising candidate owing to the high abundance and capacity of Zn metal. Currently, manganese-based and vanadium-based oxides are most common choices for cathode materials used in AZIBs, but they unfortunately show a moderate cell voltage and limited rate performance induced by slow intercalation-extraction kinetics of Zn<sup>2+</sup> ions. To address these issues, alternative cathode systems with tunable redox potentials and intrinsic fast kinetics have been exploited. In the past few years, conversion-type cathodes of I<sub>2</sub> and S have become the most illustrative examples to match or even surpass the performance of conventional metal oxide cathodes in AZIBs. Herein, we sum up most recent progress in conversion-type cathodes and focus on novel ideas and concepts in designing/modifying cathodes for AZIBs with high voltage/capacity.

It was still a formidable challenge to fabricate CPL-active perovskites with significant luminescent asymmetry factor (<em>g</em><sub>lum</sub>) and full-colour-tailorable CPL properties. Indeed, compared to isotropic perovskites, anisotropic perovskite nanowires (NWs) were conducive to carrier separation and transport for polarization enhancement. Herein, three types of CsPb(Br/I)<sub>3</sub> NWs with green, orange, red fluorescence (FL) were respectively synthesized and assembled into chiral NW films. The right-handed/left-handed chiral NW films constructed by 4+4 layers and 45° inter-angles exhibits highly symmetric and mirror-like chiral signals. The strongest chiral intensity is more than 3000 medg. CPL signals with wide colour gamut produce ranging from 480 ​nm to 800 ​nm, and tailorable CPL wavelengths are manipulated by the emission wavelength of perovskite NWs. A giant CPL signal with a maximum <em>g</em><sub>lum</sub> of up to 10<sup>−1</sup> is achieved. The polarization imaging of chiral NW films produces brilliant differential circularly polarized structural colours, making it more widely used in multilevel anti-counterfeiting systems. A significant breakthrough lies in the development of advanced chiral perovskite materials with remarkable <em>g</em><sub>lum</sub> and tailorable CPL properties, which sheds new light on optical anti-counterfeiting and intelligent information encryption.</div></div>","PeriodicalId":7283,"journal":{"name":"Advanced Powder Materials","volume":"4 1","pages":"Article 100262"},"PeriodicalIF":0.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143165287","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}
