Therefore, the solid electrolytes are required to make reliable interfaces with both high-voltage cathodes and Li-metal anodes. However, such requirement is usually difficult to be satisfied if using single-type electrolytes. Herein, a polyvinylidene fluoride (PVDF) based composite electrolyte with hierarchical-structural design from “polymer-in-salt” (PIS) to “polymer-in-ceramic” (PIC) is proposed to fulfill the double-side interface stability. Based on PVDF matrix with Li-salt as major component, the “PIS” electrolyte presents electrochemical window of as high as 4.8 V and ionic conductivity of 2.1×10−4 S cm−1. Meanwhile, through being incorporated with inorganic nanoparticles, the PVDF further endows “PIC” configuration with high mechanical strength of 5.0 MPa and electrochemical stability to restrain dendrite infiltration. Upon coupling of hierarchical electrolyte (~16 μm) with LiNi0.6Co0.2Mn0.2O2 cathode and Li anode, the resultant LiNi0.6Co0.2Mn0.2O2/Li cell delivers a remarkable capacity retention of 83.3% after 200 cycles at 0.2 C. Furthermore, an excellent capacity retention of 89.7% after 120 cycles is achieved for the corresponding pouch cell with high cathode loading of 7.6 mg cm−2 at 0.2 C. This work demonstrates a universal strategy for realizing high-stability SSLBs by adopting hierarchical electrolyte configuration.","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"13 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142917833","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, it is challenging for existing acoustic sensors to simultaneously achieve a broad spectrum and high-resolution response to speech, which is crucial for accurately achieving human beings’ smart speech recognition for human-computer interaction in artificial intelligence (AI) era. In this work, we fabricate a high-performance triboelectric acoustic sensor (HPTS) equipped with an ultra-wide band response range, capable of collecting human speech across the entire range of audible frequencies from 20 Hz to 20,000 Hz, exhibiting ultra-high frequency resolution down to 0.1 Hz. Subsequently, a multifunctional speech aided system is constructed using HPTS that is capable of effectively achieving the recognition of subtle emotional nuances, semantics and voiceprint. Enhanced by the emotional semantic recognition model (ESRM), this speech aided system has achieved a much higher accuracy in recognizing seven different human emotions, reaching an impressive accuracy of 95.43%. Additionally, it is proficient in interpreting various semantics and voiceprint from human users.

Previous studies have explored the hydrodynamics of buoys for wave energy harvesting using TENGs, but they often relied on simplified models that used a single wave period and pitch amplitude, which may not fully capture the complexity of real-world sea conditions. In this study, we present a numerical simulation model of Arctic-TENG buoy dynamics to predict and optimize its mechanical behavior in the Arctic Ocean. First, a local sea trial was conducted to collect empirical data on sea states and buoy motion. The data were used to validate the buoy simulation model, which agreed well with the sea trial results, with differences of 13.6% and 13.2% in root mean square angular displacement and angular velocity of buoy motion, respectively. The verified model was then used to predict buoy motion in the Arctic Ocean and to optimize the buoy design for greater angular amplitude and velocity, thereby enhancing TENG performance. These optimizations were experimentally validated using a custom buoy motion simulator: the maximum average power output of 2.28 mW was observed at a 20 MΩ load, and the instantaneous power output at this optimal load was recorded, showing that the majority of peak power ranged between 10 mW and 20 mW, with the maximum peak power output reaching 22 mW. This power level is sufficient to support satellite communications exceeding 500 bytes daily in ocean buoys. This work not only improved the TENG power output but also provided a comprehensive design guideline for energy harvesters in remote and harsh environments like the Arctic Ocean.","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"34 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142917672","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, integrating various advantages into one material remains a major challenge, such as high ionic conductivity, superior mechanical properties, good self-healing capacity, excellent temperature tolerance, and high output power. Here, a multiple dynamic hydrogen bond interaction strategy is proposed to prepare multifunctional biomass eutectogels composed of itaconic acid/ChCl DESs (IA-DESs) and lactic acid/ChCl DESs (LA-DESs). The introduction of LA-DESs can provide multiple hydrogen bond interactions for eutectogels and sufficient mobile charges derived from dissociated cations and anions, thereby improving mechanical property and ionic conductivity of eutectogels. Furthermore, the interactions also endow the biomass eutectogels with good self-healing property, excellent temperature tolerance, and strong interfacial adsorption. By integrating triboelectric materials, a novel biomass eutectogel-based TENG (BE-TENG) is successfully fabricated, which achieved a record-high maximum peak power density of 2.4 W m-2 in the eutectogel-based TENGs. Moreover, BE-TENG can deliver stable electrical outputs even in a stretching state, under wide temperature environments of −20 and 100 °C, and after self-healing. The BE-TENG also demonstrates efficient powering capability for portable electronics and self-powered sensing for human motions.

However, high costs and low reserves of precious metals greatly limit their development into practical applications. It is still challenging to achieve LSPR-induced enhancement in PL emission of QDs in the second near-infrared (NIR) window (900-1700 nm) for practical use, as the radiative emission rate decreases. Herein we report the synthesis of noble-metal-free Cu2-xSe@SiO2@CuInSe2-xSx/ZnS core/shell/shell hybrid NSs (C@S@S for short) in the NIR region (PL emission centered at ~917 nm). These NSs exhibit absolute PL quantum yield (QY) of ~45% (Eex=520 nm) and PL enhancement factor (EF) of 4.24 compared to the original CuInSe2-xSx/ZnS QDs. A fundamental understanding of the LSPR-enhancement mechanism in PL emission and the carrier dynamics in this NIR hybrid system has been proposed and demonstrated based on theoretical simulations and transient absorption measurements. As a proof of concept, the hybrid NSs are used to fabricate a highly transparent (visible light transmission of 89.1%) building-integrated photovoltaic (BIPV) system based on luminescent solar concentrator (LSC, dimensions of 6×6×0.3 cm3) and Si PVs, which exhibits an enhanced power conversion efficiency (PCE, 0.23%) and photostability with respect to those of sole QDs-based LSC-PV systems.
