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.

In this work, we propose and demonstrate a type of new superwettability hybrid surface for high-efficiency CHT, which consists of superhydrophobic nanoneedle arrays and triangularly-patterned superhydrophilic microdots (SMDs). Such hybrid surface can be fabricated by the facile growth of densely-packed ZnO nanoneedles on the Zn-electroplated copper surface followed by fluorosilane modification and mask-assisted photodegradation. Through regulating the diameters and interspaces of SMDs, we obtain the optimized triangularly-patterned hybrid surface, which shows 42.7 % higher CHT coefficient than the squarely-patterned hybrid surface and 58.5 % higher CHT coefficient than the superhydrophobic surface. The key of such hybrid surface design is to considerably increase CHT coefficient brought about by SMD-triggered drop sweeping at the cost of slightly reducing heat transfer area of superhydrophobic functional zone for drop jumping. Such new strategy helps develop advanced CHT surfaces for high-efficiency electronic cooling and energy utilization.</div></div>","PeriodicalId":10088,"journal":{"name":"Chinese Chemical Letters","volume":"36 3","pages":"Article 110395"},"PeriodicalIF":9.4,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143318376","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}
