However, Li3VO4 anode still faces significant challenges in terms of charge transfer kinetics and volumetric energy density. Herein, we report the large-scale preparation of boron (B) and nitrogen (N) co-doped carbon bowls anchoring ultrafine Li3VO4 nanocrystals (denoted as LVO@BNCBs) by the universal and adjustable spray drying technique, which involves the crosslinking network of boric acid (BA) and acrylic acid for carbon skeleton formation and water evaporation induced hollow morphology, followed by controlled pyrolysis. The obtained LVO@BNCBs possess a high tap density due to the stacking of porous carbon bowls, which facilitating the formation of interconnected conductive channels to promote ion transport. Thus, the LVO@BNCBs electrode demonstrated a high capacity of 592 mAh g–1 at 0.5 A g–1 and a long cycling life over 10000 cycles at 4/2 A g–1. Furthermore, the designed LVO@BNCBs//LVP full cell exhibits a power density of up to 4788.3 W kg–1, which is superior to that of the majority of existing LVO-based batteries. This scale-up synthesis of LVO@BNCBs with excellent performance expand the manufactural strategy of carbon bowls and pave the way for practical applications of LVO","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":"144 1","pages":""},"PeriodicalIF":11.9,"publicationDate":"2025-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144786930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To overcome these limitations, we developed an inorganic–organic synergy thermoelectric generator (iosTEG) that delivers superior output power, achieving 2.5 μW under a 40 K temperature gradient in a single-pair configuration, outperforming previous all-organic and hybrid FTEGs. The iosTEG was fabricated via tape-assisted exfoliation of high-crystallinity p- and n-type Bi₂Te₃ flakes, aligned on a flexible, self-healing Ni-bpyPTD polymer. Specifically, the Ni-bpyPTD matrix, synthesized through the crosslinking polymerization of PTD and 4,4′-bis(hydroxymethyl)-2,2′-bipyridine, followed by Ni²⁺ coordination, forms dynamic supramolecular networks that enable stretchability and self-repair via hydrogen bonding and metal–ligand interactions. Moreover, liquid eutectic gallium-indium (EGaIn) was employed as a deformable electrode to bridge the flakes and copper electrode terminals. Notably, the iosTEG retains its functionality upon deformation, maintaining an output voltage of 13.9 mV after stretching (cf. 17.8 mV in the undeformed state, ΔT = 30 K). The iosTEG exhibits excellent mechanical durability, maintaining stable electrical resistance under cyclic deformation, including bending to a 1.0 mm radius and stretchability up to 150%, while autonomously restoring conductivity after damage. The self-healing behavior is further validated by the recovery of R after intentional cutting, highlighting the promise of inorganic–organic integration for stretchable, durable, and high-performance energy devices.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":"30 1","pages":""},"PeriodicalIF":11.9,"publicationDate":"2025-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144787073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The obtained absorber shows improved crystallinity and passivated defects with the grain boundaries passivated. Besides, the increased S/Se ratio on the absorber surface makes the electron transport barrier at the heterojunction smaller. As a result, the interface carrier recombination decreases, and the carrier lifetime increases. The devices with Na2S treatment show obvious improvement in VOC and fill factor (FF), with a champion efficiency of 14.26%.

Strategies such as embedding Si into carbon matrices with optimized porosity and conductivity have been explored to improve capacity retention and cycling stability. Here, we report a viable two-step emulsion polymerization and carbonization technique to transform biomass into a porous amorphous carbon cloud with commercial Si nanoparticles embedded within it, referred to as Si@CC. Two types of Si@CC with similar Si contents were prepared: Si@CC1 (carbon source: Kraft lignin) and Si@CC2 (carbon source: Kraft lignin and precarbonized soyhulls). A thorough electrochemical analysis of Si@CC2 revealed an anomalous electrochemical behavior─a constant decrease of internal resistance and a downward shift in the charging plateau with cycling. Raman spectroscopy and X-ray diffraction studies revealed an in situ disorder reduction in the amorphous carbon cloud. A greater disorder reduction was observed for Si@CC2, which is attributed to the higher proportion of mesopores (2 nm < pore sizes < 50 nm). The in situ disorder reduction (first report for LIBs) originates from the interplay of Si's volume fluctuations, the low compressibility of the liquid electrolyte, and the load transfer between the liquid electrolyte, Si nanoparticles, and the carbon cloud. This phenomenon contributes to the superior capacity retention of Si@CC2 (81% after 500 cycles at 0.42 A g-1) compared to pristine Si and Si@CC1. In situ disorder reduction in amorphous carbon cloud during cycling holds promise for developing stable, long-lasting, and energy-dense Si-anode LIBs.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"288 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144787419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
