Herein, a novel deep eutectic solvent (DES)-based PEO PE for stabilizing high voltage lithium metal battery (LMB) is designed. The DES reduces the crystallinity of PEO while promoting the dissociation of LiTFSI to release more free Li+, thus facilitating the transport of Li+ in the PEO matrix. In addition, the interaction between DES and the PEO, thereby improving the stability of the PEO-based PE under high voltage. Consequently, the PEO-DES-FEC (for short PDF) PE possesses satisfactory ionic conductivity, good mechanical properties, and high electrochemical stability. Meanwhile, PDF PE can build a robust/uniform LiF-rich solid electrolyte interface (SEI) to ensure electrode/electrolyte interface stability. As a concept proof, the Li symmetrical battery and Li||LiFePO4 LMBs of PDF PE exhibit good cycle stability. Applied to the high voltage Li||NCM811 LMBs, the PDF PE-based cell has excellent cycling performance at 4.3 and 4.5 V. This tactic is one of the successful demonstrations of PEO-based electrolytes under 4.5 V high voltage conditions, which breaks through the voltage constraint of conventional PEO-based PEs.","PeriodicalId":228,"journal":{"name":"Small","volume":"193 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142678830","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 achieve even deposition of Li+, a free radical polymer (PTMA), poly (2,2,6,6-tetramethylpiperidinyloxy meth-acrylate), serving as Li+ transport and deposition mediator layer in Polyethylene oxide-Li7La3Zr2O12 (PEO-LLZO) composite solid polymer electrolytes is employed. During the transporting process, Li+ is anchored by the O· site of PTMA, hopping along PTMA chains until deposited onto the Li metal anode. This Li+ transport route is confirmed by the displacement of PTMA-6Li with PTMA-7Li and 6Li-tracing NMR. The DFT calculation confirms Li+ is more energetically preferred to coordinate with PTMA than directly deposited onto the lithium electrode, the atomic Li deposition furtherly occurs since the lower adsorption energy of Li on the Li (001) slab than Li+. Therefore, the deposition of Li+ avoids the influence of the electric field with the assistance of the PTMA mediator layer, and a molecular scale Li+ deposition is achieved since each unit of PTMA acts as an active site of lithium transition and deposition. Consequently, lithium symmetrical battery shows stable cycles 4000 h at 0.1 mA cm−2 and 60 °C. The LiFePO4/Li batteries show excellent cyclic and rate performance.","PeriodicalId":228,"journal":{"name":"Small","volume":"1 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142684983","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}

Abandoning them risks global food shortages. Urgent eco-friendly alternatives are needed for food production without excessive synthetic chemicals. To respond to this challenge, an innovative approach uses POSS polymer (PA) to modify waste bone gelatin (BG), constructinging a biodegradable triboelectric nanogenerator (PAG-TENG) tailored for the triboelectric stimulating system for seed germination (PTSS). Amide groups of PA improve the electron supplying capacity of BG and 3D cage structure captures and transfers charges of BG, thereby improving the output performance of PAG-TENG. The spatial electrostatic field formed by PAG-TENG promotes seed germination when subjected to pressure changes in the environment. Hence output performance of PAG-TENG is improved from 52.34 V and 40.25 nA to 247.15 V and 482.12 nA, the sensitivity is 14.4957 V*kPa−1. It maintains initial stable performance after the 6000 cycles of testing. Besides, the prepared PAG-TENG has good toughness, translucency, and degradability. Treated by the high voltage electrostatic field of PTSS, peas' germination rate remarkably increased by ≈27%. This work realizes the high-value utilization of waste resource BG, and provides a novel direction for the development of intelligent agriculture.","PeriodicalId":228,"journal":{"name":"Small","volume":"25 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142684935","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}

Real-time and precise tracking of these rapid pH changes within a single living cell is therefore important. However, achieving high dynamic response performance (subsecond) pH detection inside a living cell with high accuracy remains a challenge. Here a reference-attached pH nanosensor (R-pH-nanosensor) with fast and precise pHi sensing performance is introduced. The nanosensor comprises a highly conductive H+-sensitive IrRuOx nanowire (SiC@IrRuOx NW) as the intracellular working electrode and a SiC@Ag/AgCl NW as an intracellular reference electrode (RE) to diminish the interferences arising from cell membrane potential fluctuations. This whole-inside-cell detection mode ensures that the entire potential detection circuit is located within the same cell, and the R-pH-nanosensor is able to quantify the mild acidification of cytosol and completely record the fast pH variation within a single cell. It also enables real-time potentiometric monitoring of the pHi oscillations, which synchronize with the glycolysis oscillations in cancer cells. Furthermore, the asymmetry in glycolysis oscillations wave is disclosed and the inhibitory effect of just lactate to glycolysis oscillations is further confirmed.","PeriodicalId":228,"journal":{"name":"Small","volume":"66 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142684936","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}
