Osmotic energy stored in the salinity difference between seawater and river water is one of the sustainable, abundant, and renewable energy. However, the membranes used to capture osmotic energy by reverse electrodialysis (RED) always suffer from low ion selectivity, low stability and low power. Hydrogels with three-dimensional (3D) networks have shown great potential for ion transportation and energy conversion. In this work, based on the homogeneity and porosity characteristics of acrylamide (AM) hydrogel, as well as the remarkable stability and abundant negative charge of 3-sulfopropyl acrylate potassium salt (SPAK), a high-performance AM/SPAK cation-selective hydrogel membrane was successfully developed for harvesting osmotic energy. Compared to AM hydrogels, utilizing AM/SPAK as a monomer mixture greatly facilitated the preparation of homogeneous polymers, exhibiting a porous structure, exceptional ion selectivity, and remarkable stability. A maximum output power density of 13.73 W/m<sup>2</sup> was achieved at a 50-fold NaCl concentration gradient, exceeding the commercial requirement of 5 W/m<sup>2</sup>.

Benefiting from the active sites of boron (B) and phosphorus (P) doping materials, co-doped carbon materials are widely used in energy storage devices for the enhanced electrochemical performance. Herein, B and P co-doped flexible carbon nanofibers with nitrogen-rich (B-P/NC) are investigated with electrospinning for sodium-ion battery. The flexible of binderless B-P/NC with annealing of 600 °C (B-P/NC-600) exhibits the remarkable performance for the robust capacity of 200 mAh/g at 0.1 A/g after 500 cycles and a durable reversible capacity of 160 mAh/g even at 1 A/g after 12,000 cycles, exhibiting the equally commendable stability of flexible B-P/NC-600. In addition, B-P/NC-600 delivers the reversible capacity of 265 mAh/g with the test temperature of 60 °C. More importantly, the flexible B-P/NC-600 is fabricated as anode for the whole battery, delivering the capacity of 90 mAh/g at 1 A/g after 200 cycles. Meanwhile, theoretical calculation further verified that boron and phosphorus co-doping can improve the adsorption capacity of nitrogen carbon materials. The favorable performance of flexible B-P/NC-600 can be ascribed to the nitrogen-rich carbon nanofibers with three-dimensional network matrix for the more active site of boron and phosphorus co-doping. Our work paves the way for the improvement of flexible anodes and wide-operating temperature of sodium-ion batteries by doping approach of much heteroatom.</div></div>","PeriodicalId":10088,"journal":{"name":"Chinese Chemical Letters","volume":"36 1","pages":"Article 110452"},"PeriodicalIF":9.4,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142572691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the innate low energy level of lowest unoccupied molecular orbital (LUMO) in EC makes it incompatible with lithium metal, causing uncontrolled lithium growth and low Coulombic efficiency (CE). Herein, we introduced bis(2,2,2-trifluoroethyl) carbonate (TFEC), a carbonate with a strong electron-withdrawing effect (-CF<sub>3</sub>), which enhances the stability of EC at electrode interface by reducing ion-dipole interactions between Li<sup>+</sup> and EC. As the interaction between Li and EC weakens, TFEC and more PF<sub>6<sup>−</sup></sub> anions coordinate with Li⁺, promoting the formation of contact ion pairs (CIPs) and aggregates (AGGs), thereby increasing the inorganic composition within the solid electrolyte interphase. Additionally, the distinct solvated sheath structure favors the decomposition of fluorinated solvents and PF<sub>6−</sub> anions, forming inorganic-rich electrode-electrolyte interfaces (SEI and CEI), thereby ensuring high stability for both the Li anode and high-voltage cathode.
