However, OEMs reported thus far are still severely limited by poor electrical conductivity and unsatisfactory capacity. Herein, we creatively propose to directly conjugate the active motifs with functional linkers in OEMs for simultaneously increasing conductivity and capacity. As the first attempt, an exclusive azo-bridged covalent triazine frameworks (Azo-CTF) where triazine motifs are directly linked with azo groups, is cleverly designed and constructed. By virtue of the thoroughly electron conjugation throughout azo bridges and triazine π units, Azo-CTF with the lowest energy bandgap (2.62 eV) exhibits excellent essential charge conductivity. More excitingly, Azo-CTF achieves maximum redox-active sites integration (with the mass ratio reached to 70%) to date. Therefore, Azo-CTF anode shows an almost record performance with a high reversible capacity (2332.8 mAh g-1 at 0.1 A g-1) and inspiring rate characteristics (1034.4 mAh g-1 undergoing 500 cycles at 2 A g-1, 690.2 mAh g-1 undergoing 1000 cycles at 5 A g-1). Our work provides a new strategy for synchronously improving the conductivity and capacity of OEMs, which would greatly promote the development of lithium organic batteries.","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"27 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143471022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we present a ferrofluid-based triboelectric pressure sensor (FTPS) based on a strain-concentrated dual tip-array design between the liquid and solid phases. A silicone rubber film with a conical micro/nanostructure array and a ferrofluid with incisive spike microstructures tuned by a solid baseplate are employed as triboelectric pairs. The array-shaped microstructures of the solid- and liquid-sensing layers exhibit an opposing arrangement, manifesting a dual tip-array structure. The strain concentration effect arises from the coupling of high hydrophobicity caused by solid tip microstructures and high sharpness of liquid tip microstructures. In a load-bearing structure, there is a significant increase in strain when a sudden change in shape occurs. The sensitivity of the FTPS is positively correlated with the vertical deformation at the interface per unit pressure. Thus, an unprecedentedly high sensitivity of 38.84 kPa−1 and an inconceivably low detection limit of 0.76 Pa are attained. Finally, wind speed and direction detection with high sensitivity and stability based on the FTPS is demonstrated, indicating extensive practical applications for environmental monitoring and meteorological forecasting.","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"52 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143471065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this, the fluorinated organic sulfate 4-(trifluoromethyl)-1,3,2-dioxathiolane 2,2-dioxide (TFDTD) was developed as an effective additive for tailoring organosulfur-based electrolytes in lithium-ion batteries. This development was guided by the functionality selection principle and careful evaluation of feasibility in organic synthesis. TFDTD can be readily synthesized through the reaction between trifluoropropylene glycol and sulfuryl chloride. The ring structure of the organic sulfate enables the formation of a stable SEI on the anode, while the fluorination of the sulfate not only enhances its chemical stability and oxidation potential, but also its effectiveness to protect the anode by increasing its reduction potential, rendering it preferentially reduced on the anode surface before the decomposition of other electrolyte components. Introducing TFDTD facilitates the generation of a robust solid-electrolyte interphase on the graphite anode, significantly enhancing cell performance. Moreover, coupling the use of TFDTD with vinylene carbonate provides further protection on the cathode surface, enabling exceptionally stable, high-voltage, long-term cycling of Gr||NMC full cells.","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"6 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143462345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the unsatisfactory electrochemical performance of Cu3P due to the sluggish rate and poor stability severely limited the development of practical application in electrochemical Cl− removal. Herein, monolithic low-tortuous Cu3P nanorod arrays (mCu3P NA) have been fabricated through sacrificial template array engineering combined with the controlled phosphating strategy. Benefiting from the low-tortuous array structural advantages involving rapid charge transfer and plentiful active sites, the resultant mCu3P NA electrode exhibited excellent areal deionization capacity (2.21 mg-Cl− cm−2 at 1.6 V) and corresponding fabulous rate (0.074 mg-Cl− cm−2 min−1), which was superior to previously reported electrodes in electrochemical deionization. Furthermore, the phosphating degree could adjust array architecture and component of Cu3P/Cu heterostructure, thus affecting areal deionization performance. In addition, the mechanism of Cl− capture by Cu3P was first elucidated, related to the redox of P3−/P0 and the formation of CuCl. These findings unlock the potential and elucidate the mechanism of Cu3P for electrochemical Cl− removal, as well as provide a new idea for rational design of high-performance array electrodes for environmental applications.","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"34 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143462348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results revealed that 25 wt% BTO content in the functional film yields the highest electrical output of the PENG, and this functional film maintains a stable output even after multiple reconfigurations. Furthermore, the BTO-CNF piezoelectric film provides PENGs with lower internal resistance, enabling compact integration with conventional circuits and showcasing great potential in the field of self-powered smart microsystems, particularly those requiring remarkable reconfigurable properties.

A vertically aligned stacking channel of the WSe2 thin film was obtained by converting a WOx thin film using a plasma-assisted selenization process. With the insertion of the WSe2 layer, we observed a notable accumulation of Ga at the rear side of the CIGS absorber layer, facilitated by the vertically channel-stacked WSe2 thin film. Increased open-circuit voltage is attributed to the reconstruction of the band alignment due to the modified Ga concentration profile, effectively mitigating electron flowing toward back contact and recombination within the back contact region of the CIGS solar cell. Furthermore, a favorable conductivity along the channels of the vertically channel-stacked WSe2 thin film and a steeper [Ga]/([Ga] + [In]) (GGI) gradient provide significant enhancements in short-circuit current density.

This study introduces a magnet gear-based TENG, designed to harness energy from boiling environments. The magnet gear facilitates remote force transmission from the rotor to the TENG module, effectively mitigating the adverse effects of high temperature and humidity. Rabbit fur is used to create a soft contact, enhancing coupling with the low-grade energy source, significantly reducing frictional resistance, and improving device durability. Tests demonstrate that the M-TENG does not impact the thermal management of boiling heat transfer, showing potential for integration with other thermal energy harvesting techniques. Its operational range spans the boiling curve from nucleation to critical heat flux, maintaining performance after 15,000 cycles.
