As a preparation step for practically utilizing LSBs, there is a problem, wherein battery cycle life rapidly reduces as the loading level of the sulfur cathode increases and the electrode area expands. In this study, a separator coated with boehmite on both sides of polyethylene (hereinafter denoted as boehmite separator) is incorporated into a high-loading Li-S pouch battery to suppress sudden capacity drops and achieve a longer cycle life. We explore a phenomenon by which inequality is generated in regions where an electrochemical reaction occurs in the sulfur cathode during the discharging and charging of a high-capacity Li-S pouch battery. The boehmite separator inhibits the accumulation of sulfur-related species on the surface of the sulfur cathode to induce an even reaction across the entire cathode and suppresses the degradation of the Li metal anode, allowing the pouch battery with an areal capacity of 8 mAh cm–2 to operate stably for 300 cycles. These results demonstrate the importance of customizing separators for the practical use of LSBs.","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"29 1","pages":""},"PeriodicalIF":20.5,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142211836","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}

Because of the direct contact between the carbon electrode and the perovskite surface, energy barriers and defects at the interface limit the enhancement of power conversion efficiency (PCE). In this work, we first reported a preparation method of CsPbI2.75Br0.25 HTL-free C-IPSCs and developed an effective surface sulfidation regulation (SSR) strategy to promote hole extraction and inhibit non-radiative recombination of inorganic perovskite by 2-(thiocyanomethylthio)benzothiazole (TCMTB) surface modification. The introduced S2− anions form strong binding with uncoordinated Pb ions, inhibit the perovskite degradation reaction, and effectively passivate the surface defects. In addition, PbS formed by the SSR strategy constructed a gradient heterojunction, which promoted the arrangement energy levels and enhanced hole extraction. An additional back-surface field is induced at the interface of perovskite by energy band bending, which increases the open-circuit voltage (VOC). As a result, the SSR-based CsPbI2.75Br0.25 HTL-free C-IPSCs showed a PCE of 17.88% with a fill factor of 81.56% and VOC of 1.19 V, which was among the highest reported values of CsPbI2.75Br0.25 HTL-free C-IPSCs.","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"28 1","pages":""},"PeriodicalIF":20.5,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142211857","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}

With the progress of human society, the requirements for energy storage systems in extreme environments, such as deep-sea exploration, aerospace missions, and tunnel operations, have become more stringent. The comprehensive performance of NIBs at low temperatures (LTs) has also become an important consideration. Under LT conditions, challenges such as increased viscosity of electrolyte, abnormal growth of solid electrolyte interface, and poor contact between collector and electrode materials emerge. The aforementioned issues hinder the diffusion kinetics of sodium ions (Na+) at the electrode/electrolyte interface and cause rapid degradation of battery performance. Consequently, the optimization of electrolyte composition and cathode/anode materials becomes an effective approach to improve LT performance. This review discusses the conduction behavior and limiting factors of Na+ in both solid electrodes and liquid electrolytes at LT. Furthermore, it systematically reviews the recent research progress of LT NIBs from three aspects: cathode materials, anode materials, and electrolyte components.

The Ni3(HITP)2 material was deposited on the surface of the Ge anode to prevent corrosion and passivation reactions inside the battery. At 16°C, the discharge time of Ge anodes protected with MOFs was extended to 59 h at 195 μA cm−2, which was twice that of bare Ge anodes. The positive effect of MOFs on Ge–air batteries at high temperatures was observed for the first time. The Ge@Ni3(HITP)2 anodes discharged over 600 h at 65.0 μA cm−2.

However, the impedance mismatch from high conductivity and their singular mode of energy loss hinder effective EM wave dissipation. Construction of cable structures not only optimizes impedance matching but also introduces a multitude of heterojunctions, increasing attenuation modes and potentially enhancing EM wave absorption (EMA) performance. Herein, we showcase the scalable synthesis of tin (Sn) whiskers from a Ti2SnC MAX phase precursor, followed by creation of a 1D tin@carbon (Sn@C) cable structure through polymerization of PDA on their surface and annealing in argon. The EMA capabilities of Sn@C significantly surpass those of uncoated Sn whiskers, with an effective absorption bandwidth reaching 7.4 GHz. Remarkably, its maximum radar cross section reduction value of 27.85 dB m2 indicates its exceptional stealth capabilities. The enhanced EMA performance is first attributed to optimized impedance matching, and furthermore, the Sn@C cable structures have rich SnO2/C and Sn/SnO2 heterointerfaces and the associated defects, which increase interfacial and defect-induced polarization losses, as visually demonstrated by off-axis electron holography. The development of the Sn@C cable structure represents a notable advancement in broadening the scope of materials with potential applications in stealth technology, and this study also contributes to the understanding of how heterojunctions can improve EMA performance.","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"7 1","pages":""},"PeriodicalIF":20.5,"publicationDate":"2024-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142211861","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}
