However, rapid capacity degradation and sluggish diffusion kinetics, caused by structural distortions and irreversible phase transitions, present significant challenges to its commercial application. In this study, we design a series of O3-NaNi_1/3-xFe_1/3Mn_1/3Al_xO₂ cathodes with varying Al³⁺ doping concentrations, synthesized through a one-step liquid-phase modified precursor method followed by post-calcination. Notably, an optimal level of Al³⁺ substitution at the transition metal sites significantly enhances the structural stability during long cycling. However, excessive Al doping at the Na-site hampers sodium-ions diffusion, thereby limiting the rate performance. The optimal performance is achieved with the O3-NaNi_1/3-0.005Fe_1/3Mn_1/3Al_0.005O₂ cathode, which exhibits remarkable overall electrochemical performance including a high specific capacity of 151 mAh g^-1 at 1 C, superior cycle stability with 85% capacity retention after 150 cycles in a half cell, and improved rate performance (74 mAh g^-1 at 10 C). This work provides valuable insights into the behavior of inactive element substitution, offering a pathway for the development of long-cycle life O3-type oxide cathodes and contributing to novel materials design strategies.","PeriodicalId":305,"journal":{"name":"Electrochimica Acta","volume":"32 1","pages":""},"PeriodicalIF":6.6,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143867201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fiber reinforced membranes are in two distinct phases, a rigid crosslinked polybenzimidazole fiber mat within a continuous polybenzimidazole matrix. This was found to promote the anisotropic swelling during the subsequent phosphoric acid doping, i.e. suppressing the area swelling while enhancing the thickness swelling.

However, when degradation occurs, battery performance becomes unreliable. Thus, accurate identification of the battery performance during the long cycle is especially important. In this paper, the performance of LiFePO₄/graphite cells cycled at different rates to 5000 cycles is compared in detail. During the cycle, the voltage, capacity, and reference performance tests are recorded to find the method for cell state assessment under operating conditions. We find that the voltages acquired from the end of the rest period can reflect the cell state of charge to some extent. The capacity differences between operating conditions and the capacity increase during the early cycle stage of rate discharge can all be explained clearly in terms of the changes in their corresponding rest voltages. Moreover, the voltage differences between the end of the rest period and the start of the operation are useful parameters to evaluate the change in ohmic polarization with the cycle. In addition, a non-destructive method is proposed by comparing the voltage and corresponding differential voltage curves of the cell and the two separate electrodes. Based on this method, the ageing states of cells cycled under different conditions are quantitatively evaluated. An increased capacity ratio of negative to positive during the cycle is discovered in cells with better cycle performance, providing theoretical support for cell design with ultra-long cycles.","PeriodicalId":305,"journal":{"name":"Electrochimica Acta","volume":"42 1","pages":""},"PeriodicalIF":6.6,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143867204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study employs electrochemical impedance spectroscopy (EIS), surface-enhanced infrared absorption spectroscopy (SEIRAS), and Langmuir trough experiments to unravel the multifaceted mechanism of calcium-induced blockage of gA channels in a DOPC lipid bilayer. The findings reveal that calcium ions interact with the polar headgroups of DOPC lipids, inducing dehydration and increased packing density, which reduce the mobility of gramicidin monomers. Structural analysis highlights significant elongation of the gA helices, weakening of hydrogen bonds, and a shift in the conformational equilibrium towards inactive monomeric forms. These observations challenge the conventional view of calcium ion blockage being solely due to steric hindrance, proposing instead a broader mechanism involving alterations in both the membrane environment and peptide structure.
