MXenes show promising pseudocapacitive behaviors, however, the poor thermodynamical and mechanical stability makes them unfavorable for applications under complex and harsh environments. Herein, we break these limitations by aramid nanofibers (ANF)-driven interfacial nanofilling and hydrogen-bonds effects in MXenes. Theoretical and experimental results unveil that ANF with unique polarity preferentially interacts with H<sub>2</sub>O molecules and forms hydrogen bonding networks to restrain oxidative and mechanical attack toward MXene, at the same time, the nanofilling enables interfacial mass transport intensification for increment in redox dynamics. As such, the synergistically coupled ANF-MXene microstructure (AM) unlocks superior mechanical properties for facing hash forces, i.e., tensile strength of 115.2 MPa and toughness of 1.8 MJ m<sup>-3</sup>, and an ultra-long cycling life with a capacitance retention of 90.7% after 40,000 cycles. Besides, the effective IR thermal camouflage performance (IR-emissivity: 20.9%) further renders the power supply working invisibly after fast charge/discharge-driven heat generation. Moreover, the performances can be well maintained when subjected to strong acid/alkali, high-temperature (200°C), and cryogenic (-196°C) treatments. These results highlight the key role of interfacial species synergy in accelerating versatile and robust energy applications.","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"22 1","pages":""},"PeriodicalIF":20.4,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142665483","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}

Overdischarge stress is an effective approach to accelerate battery aging, whereas its impact on solid electrolyte interphase (SEI) and battery aging performance remains elusive. Herein, the whole picture of SEI evolution under different overdischarge levels was quantitatively illustrated by combining the electrochemical analysis and spectrochemical techniques. Overdischarge leads to the decomposition of the organic components within SEI, such as ROCO<sub>2</sub>Li and CH<sub>3</sub>Li, while the damaged SEI is repaired during the subsequent charging process with its composition and structure reconstructed. Under overdischarge conditions, the SEI undergoes continuous cycles of destruction and repair, which suppresses its growth and evolution to inorganic components, resulting in a thinner and more uneven morphology with higher organic components and a lower Young's modulus. The unique SEI evolution mechanism of overdischarge effectively accelerates the loss of active lithium and exhibits similar thermodynamic degradation modes to normal aging, making overdischarge a potential accelerated aging method. This study provides a deeper understanding of the mechanisms behind accelerated aging in batteries and offers new insights into the evaluation and enhancement of battery performance.","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"51 1","pages":""},"PeriodicalIF":20.4,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142665522","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}

The combination of comprehensive experimental results and simulation calculations demonstrated that the spontaneous assembly of the interfacial molecular layer (IML), facilitated by the adaptive adsorption of Pul molecules, not only triggers the formation of a Zn²⁺-concentrated region and effectively balances ionic flux, but also simultaneously transforms the nucleation growth pattern of Zn<sup>2+</sup> into an instantaneous and progressive hybridized mechanism, reconfiguring the Zn<sup>2+</sup> transfer/deposition kinetics at the heterogeneous electrode/electrolyte interface.

Herein, owing to the abundance of zincophilic functional groups, aminoglycosides represented by amikacin are introduced as sulfates to solve these problems. The presence of zincophilic functional groups, such as amino and hydroxyl, enables amikacin to effectively replace H<sub>2</sub>O molecules, thereby altering the solvation structure of Zn<sup>2+</sup>.

However, its commercial adoption is hindered by the unstable LNMO/electrolyte interface due to high operating voltages and structural degradation arising from Jahn-Teller distortion and metal-ion dissolution resulting in poor cycling stability. Additionally, the high-temperature calcination beyond 700°C often results in secondary phases such as rock salt NiO, Li<sub>1-x</sub>Ni<sub>x</sub>O, Ni<sub>6</sub>MnO<sub>8</sub> or Li<sub>2</sub>MnO<sub>3</sub>, whose precise chemical compositions and their influence on electrochemical performance remain unclear. Traditional analytical techniques such as X-ray diffraction (XRD) or neutron diffraction face challenges in resolving these secondary phases due to low phase fractions and overlapping reflections with the LNMO phase. Here, we address these challenges using correlative Raman-Scanning electron microscopy (Raman-SEM) to characterize secondary phases in LNMO materials that were synthesized under various synthesis conditions and evaluate their impact on the electrochemical performance. Our results reveal the synthesis-dependent emergence of three distinct secondary phases in LNMO materials synthesized at 1000°C, a phenomenon that, to our knowledge, has not been previously reported. Specifically, LNMO synthesized at 900°C shows the coexistence of Ni<sub>6</sub>MnO<sub>8</sub> and Li<sub>2</sub>MnO<sub>3</sub> phases, while synthesized at 1000°C also exhibits a Mn<sub>3</sub>O<sub>4</sub> phase. Furthermore, an increased amount of these secondary phases in LNMO led to a lower discharge capacity due to their electrochemical inactive nature. However, these phases do not affect the rate capability or the long-term cycling performance of the LNMO materials.

Herein, we report a voltage-driven molecular switch through a reversible transition of the nicotinic molecules between zwitterion and anion to enable deep cycled zinc metal battery. In light of <em>in-situ</em> Raman, the switching mechanism of nicotinic molecules in the electrical double layer is unveiled: during plating, nicotinic molecules switches to zwitterion mode (ON state) with periodical pyridine-ring-substrate adlayer while during stripping, shifts to anion mode with periodical carbonyl group-substrate adlayer (OFF state). The transition of NA molecules enables molecular flipping on the substrate due to the electrostatic force and in this way, in both ON and OFF state, the zinc anode is protected by the adlayer to avoid the zinc corrosion on the anode side. Furthermore, the OTF<sup>‒</sup> decomposition is accompanied by the open ring reaction of N‒heterocyclic from nicotinic acid molecules to form highly elastic solid electrolyte interface layer. Benefiting from both the molecular switch function and solid electrolyte interface layer formation, the nicotinic molecules-based electrolyte enables practical zinc metal battery of high energy density (100 Wh/kg<sub>electrode</sub>) for over 800 cycles with a cumulative capacity of 2.71 Ah cm<sup>−2</sup> at practical condition of low N/P ratio of 2, and lean electrolyte of 10 μL mAh<sup>−1</sup>, representing the state-of-the-art performance.
