Alternative routes based on the Thomson and Nernst effects offer new possibilities. Here, we present a comprehensive investigation of the thermoelectric properties of 1T-TiSe₂, focusing on these effects around the charge density wave transition (≈200 K). The abrupt Fermi surface reconstruction associated with this transition leads to an exceptional peak in the Thomson coefficient of 450 μV K⁻¹ at 184 K, surpassing the Seebeck coefficient. Furthermore, 1T-TiSe₂ exhibits a remarkably broad temperature range (170–400 K) with a Thomson coefficient exceeding 190 μV K⁻¹, a characteristic highly desirable for the development of practical Thomson coolers with extended operational ranges. Additionally, the Nernst coefficient exhibits an unusual temperature dependence, increasing with temperature in the normal phase, which we attribute to bipolar conduction effects. The combination of solid–solid pure electronic phase transition to a semimetallic phase with bipolar transport is identified as responsible for the unusual Nernst trend and the unusually large Thomson coefficient over a broad temperature range.</p>","PeriodicalId":11554,"journal":{"name":"Energy & Environmental Materials","volume":"8 4","pages":""},"PeriodicalIF":13.0,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eem2.12879","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144191229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents a facile synthesis approach for nickel-intercalated MXene, designed to enhance surface reactivity, avoid restacking, and achieve improved electrochemical performance. Electrochemical studies revealed that the nickel-MXene hybrid showed better cycling stability, retaining 83.7% of its capacity after 10 000 cycles and attaining an energy density of 26 Wh kg⁻¹ at a power density of 1872 W kg⁻¹. It also exhibited overpotentials of 109 and 482 mV at 10 and 100 mA cm⁻², respectively, in the hydrogen evolution reaction. To predict the structural and electrical alterations caused by nickel inclusion, as well as to understand the intercalation mechanism, spin-polarized density functional theory calculations were carried out. The theoretical results showed an improved carrier concentration for nickel-MXene. Nickel-MXene possessed superior electronic characteristics and surplus active sites with hexagonal closed-packed (hcp) edge sites, which enhanced electrochemical properties.

This paper innovatively proposes a strategy aimed at constructing a one-dimensional heterostructure (Fe–NiO/NiMoO₄ nanoparticles/nanofibers). The strategy commences with the meticulous treatment of NiMoO₄ nanofibers, utilizing in situ etching techniques to induce the formation of Prussian Blue Analog compounds. In this process, [Fe(CN)₆]³⁻ anions react with the NiMoO₄ host layer to form a steady NiFe PBA. Subsequently, the surface/interface reconstituted NiMoO₄ nanofibers undergo direct oxidation, leading to a reconfiguration of the surface structure and the formation of a unique Fe–NiO/NiMoO₄ one-dimensional heterostructure. The catalyst showed markedly enhanced electrocatalytic performance for the oxygen evolution reaction.

However, the pursuit of batteries capable of extremely fast charging that also satisfy high energy and safety criteria, poses a significant challenge to current lithium-ion batteries technologies. Additionally, the increasing demand for aluminum (Al) and copper (Cu) in electrification, solar energy technologies, and vehicle light-eighting is driving these metals toward near-critical status in the medium term. This study introduces metalized polythylene terephthalate (mPET) polymer films by depositing an Al or Cu thin layer onto two sides of a polyethylene terephthalate film—named mPET/Al and mPET/Cu, as lightweight, cost-effective alternatives to traditional metal current collectors in lithium-ion batteries. We have fabricated current collectors that significantly reduce weight (by 73%), thickness (by 33%), and cost (by 85%) compared with traditional metal foil counterparts. These advancements have the potential to enhance energy density to 280 Wh kg⁻¹ at the electrode level under 10-min charging at 6 C. Through testing, including a novel extremely fast charging protocol across various C-rates and long-term cycling (up to 1000 cycles) in different cell configurations, the superior performance of these metalized polymer films has been demonstrated. Notably, mPET/Cu and mPET/Al films exhibited comparable capacities to conventional cells under extremely fast charging, with the mPET cells showing a 27% improvement in energy density at 6 C and maintaining significant energy density after 1000 cycles. This study underscores the potential of mPET films to revolutionize the roll-to-roll battery manufacturing process and significantly advance the performance metrics of lithium-ion batteries in electric vehicles applications.</p>","PeriodicalId":11554,"journal":{"name":"Energy & Environmental Materials","volume":"8 4","pages":""},"PeriodicalIF":13.0,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eem2.12878","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144190744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
