Here, we present a facile solid-phase sintering approach combined with ultrasonically-assisted stripping to synthesize large-scale 2D (FeMnCoNiCu)PSe₃ (HEPSe₃) with high entropy. The incorporation of multi-cations effectively mitigates the issues associated with poor electrical conductivity and susceptibility to structural collapse observed in transition metal phosphorus tri-selenide materials. The well-designed HEPSe₃ exhibits a high discharge capacity reaching 728 mAh g⁻¹ after 250 cycles at a current density of 100 mA g⁻¹ in lithium-ion batteries, and a long-life time of 4000 cycles with a high capacity of 488 mAh g⁻¹ under high current density (10 A g⁻¹). It also performs an outstanding rate performance. Density functional theory computations demonstrate that the cooperative interactions among multiple cations within high entropy architectures substantially lower the ion migration energy barriers of HEPSe₃. Additionally, when comes to pouch-type full cell, the HEPSe₃ performs a gravimetric energy density of 382.1 Wh kg⁻¹. This study provides strong evidence to support the prospective applicability of HEPSe₃ in alkali-ion batteries, while representing significant advancements towards leveraging 2D metal phosphorus tri-selenide layered materials in energy storage devices.</div></div>","PeriodicalId":18227,"journal":{"name":"Materials Chemistry and Physics","volume":"343 ","pages":"Article 130998"},"PeriodicalIF":4.3,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144137796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This unique property enables them to store and release energy efficiently, making them ideal for various applications in electronics and energy systems. Their advanced performance positions them at the forefront of energy storage technology. This characteristic exceeds that of their linear counterparts, making them pivotal in advancing the compactness and lightweight design of electric power systems. Yet, within the realm of ferroelectrics lies a complex challenge: striking a balance between energy density and a spectrum of other indispensable properties. Among these, energy efficiency, temperature and frequency stabilities, and resistance to cycling fatigue reign paramount. Navigating these intricate dynamics is imperative for unlocking the full potential of ferroelectrics in practical applications. In this study, we focus on domain engineering as a method to manipulate the structure of materials by fragmenting them into polar nano regions. This strategic approach aims to enhance energy efficiency while maintaining high energy density levels. Our investigation centers on the utilization of the BZT-SrBiT (<em>x</em> = 0.6 &amp; 0.7), lead-free solid-solution system as a representative example to illustrate this concept. Our findings impressively demonstrate a substantial energy density of 2.92 J/cm³, accompanied by an efficiency rating of 80.13 %. This accomplishment underscores our strategy's effectiveness in enhancing energy storage capabilities while preserving performance metrics. It reflects our dedication to advancing technology that meets the growing demands of the market without sacrificing quality or efficiency. Additionally, the system exhibits remarkably narrow hysteresis loops, indicating minimal energy loss during polarization reversal. Additionally, across a broad spectrum of temperatures and frequencies ranging from 40 °C to 150 °C and 1Hz, respectively, the high energy density of 4.46 J/cm³ and efficiency of 80.13 % at an electric field strength of 150 kV/cm exhibit marginal variations of only ±3 % to ±5 %.

Consequently, detecting Tc at trace concentrations through methods that are cost-effective, rapid, and highly selective remains a critical and ongoing research challenge. Carbon paste sensors (CPS) are widely recognized as versatile tools for electrochemical sensing applications. A particularly promising approach for enhancing sensor performance involves incorporating cost-effective and eco-friendly agro-industrial residues, such as biosilica derived from sugarcane ash. This study proposes the modification of CPS with commercial silica gel (Si-CPS) and biosilica (BioSi-CPS) for the electrochemical detection of Tc. Experimental findings demonstrate that Tc efficiently accumulates on the surface of the modified sensors, significantly enhancing their oxidation current response. Differential pulse voltammetry (DPV) was employed to evaluate Tc detection, with BioSi-CPS exhibiting superior electrochemical performance. This enhancement is attributed to the increased electroactive surface area and improved electrochemical properties introduced by the biosilica modification. Using BioSi-CPS, Tc was reliably detected at low concentrations, exhibiting linear response ranges of 6–80 μmol L⁻¹ and 100–1000 μmol L⁻¹. The sensor demonstrated excellent stability and reproducibility, with no significant interference from common excipients such as glucose, ascorbic acid, citric acid, and mannose.
