A self-adaptive inorganic in-situ separator by particle crosslinking for nonflammable lithium-ion batteries

Journal of Energy Chemistry 2025年第1期100卷 469-480页

作者： Jiarui Yang Jiuzhou Liu Wenrui Cai Ziyu zhao Shan Wang Lu He Shanshan Lv Zhiwei Zhu Zhongfeng Ji Guojiang Wen Hua Li yuanming Zhai Xuewei Fu Wei Yang yu Wang College of Polymer Science and Engineering State Key Laboratory of Polymer Materials Engineering Sichuan University

All-safe liquid-state lithium-ion batteries(ASLS-LIBs) is of great interest as they can potentially combine the safety of all-solid-state batteries with the high performance and low manufacturing cost of traditional liquid-state LIBs. However, the practical success of ASLS-LIBs is bottlenecked by the lack of advanced separator technology that can simultaneously realize high performances in puncturing-tolerability,fire-resistance, and importantly, wetting-capability with non-flammable liquid-electrolytes. Here, we propose a concept of inorganic in-situ separator(IISS) by hybrid-sol physical crosslinking directly onto the electrode surface to address the above challenges. Particularly, the hybrid-sol is designed with silica nanoparticles as the building block and poly(vinylidene difluoride) nanoparticles as the crosslinking agent. The critical factors for controlling the IISS microstructures and properties have been systematically investigated. The advantages of the IISS have been confirmed by its fast wetting with various fireresistant liquid-electrolytes, customizable thickness and porous structures, robust interface with planar or three-dimensional(3D)-structured electrodes, and importantly, unexpected self-adaptability against puncturing. Enabled by the above merits, a fire-resistant ASLS-LIB is successfully assembled and demonstrated with stable electrochemical performance. This sol-crosslinked IISS may open an avenue for the studies on the next-generation separator technology, cell assembling, solid electrolyte processing as well as non-flammable secondary batteries.

Despite considerable research underscoring the importance of carbohydrate intake in relation to the risk of type 2 diabetes(T2D), a comprehensive assessment of this relationship is currently lacking. We aimed to examine the associations of various types and food sources of dietary carbohydrate intake with the risk of T2D, to evaluate potential effect modification by other factors, including genetic susceptibility,and to explore the potential mediators for such associations. The present study included 161,872 participants of the UK Biobank who were free of prevalent cancer, cardiovascular disease, or diabetes, and had at least one validated 24-h dietary recall assessment. Multivariableadjusted age-stratified Cox proportional hazard regression models were applied to estimate hazard ratios(HRs) and 95% confidence intervals(CI) for the associations of various types and food sources of dietary carbohydrate intake with risk of T2D. During a median follow-up of13.6 years, 4,176 incident cases of T2D were identified. In the multivariable-adjusted models, a greater intake of fiber, carbohydrates from whole grains, and carbohydrates from non-starchy vegetables was significantly associated with a lower risk of T2D(highest vs. lowest quantile, HR [95% CI]=0.70 [0.62–0.79], 0.74 [0.67–0.82], and 0.83 [0.75–0.92], respectively, all P for trend <0.005). In contrast, a higher intake of starch and carbohydrate from starchy vegetables was associated with an increased risk of T2D(highest vs. lowest quantile, HR [95%CI]=1.31 [1.16–1.48] and 1.19 [1.09–1.31], respectively, both P for trend <0.005). Replacing one serving of refined grains or starchy vegetables with an equal amount of whole grains or non-starchy vegetables was associated with 4% to 10% lower risk of T2D(all P values <0.001).The observed associations were generally similar across population subgroups, including individuals with different genetic susceptibility to T2D.

目的分析大肠埃希菌对喹诺酮类药物的耐药机制。方法菌株来源于2013年1月-2016年12月医院患者分离的大肠埃希菌348株,排除同一患者同一部位分离出的重复病原菌,采用琼脂稀释法,按照《美国临床实验室标准协会》(CLSI)2007年标准计算分离菌株的最低抑菌浓度值(MIC)。筛选出耐药菌株,加入7种常用抗菌药物,测定其他抗菌药物对喹诺酮类耐药菌株的药敏情况。提取耐药大肠埃希菌株的DNA,加入适宜引物,进行扩增,并进行比对分析。结果在分离的大肠埃希菌中为喹诺酮类非敏感菌株87株占25.00%,87株喹诺酮类非敏感菌株对庆大霉素、阿米卡星、头孢噻肟、头孢吡肟、头孢曲松、头孢他啶6种抗菌药物的耐药率均超过50.00%。大肠埃希菌中gryA耐药基因的突变主要发生于低水平的MIC耐药菌株,而parC和PMQR的耐药基因均主要发生在MIC值在4~8μg/ml、16~64μg/ml两个浓度区间的耐药菌株。gryA基因S83L、D87N两个位点,及gryC基因的S80I、A108V两个位点的突变情况在MIC值各个范围内突变发生情况无显著性差异。结论喹诺酮类抗菌药物非敏感的大肠埃希菌对很多其他的抗菌药物也具有耐药性,大肠埃希菌中的耐药基因同喹诺酮类抗菌药物的MIC值分布上具有一定的相关性。

Science China Technological Sciences 2025年

作者： yuzhang WEN Mengqi ZHANG Zhenning XIE Zida AN Bing LIU Fengxin SUN Tianming zhao Zuojun yu Fei WANG yupeng MAO Physical Education Department Northeastern University(Shenyang) Faculty of Robot Science and Engineering Northeastern University Criminal Investigation Police University of China State Key Laboratory of Robotics Shenyang Institute of Automation Chinese Academy of Sciences China Ice Sports College Beijing Sport University

Intelligent interaction technology based on advanced sensing units has become a research hotspot. In this paper, an intelligent interaction system (IIS) based on a multimodal conformal triboelectric nanogenerator patch (MCTP) is reported for sports monitoring and life promotion of the disabled. This IIS consists of a cloud-based smart sports recognition program and a smart life application. The porous micro-reinforced structure of polyurethane (PU) Sponge&Ecoflex, and the surface modification of PTFE by coating it with MXene endows the MCTP with excellent electrical properties. It shows good angle and force sensitivities of 1.1 V/°and 1.61 V/N, respectively, and has an ultra-fast response time of 15 ms, meeting the needs of human motion monitoring. The MCTP can also capture the mechanical energy, producing a maximum output power of 139μ*** with the commercial inertial measuring unit (IMU), the MCTP shows better consistency in human joint angle sensing. A precise analysis of wheelchair curling sports monitoring points is achieved by combining the MCTP and the human anatomy model. The cloud-based smart sports recognition program utilizes machine learning to achieve visual feedback on the three throwing technologies of draw, takeout and clearing. In addition, the developed smart life application uses a highsensitivity MCTP-sensor array design to achieve a variety of smart home interactions through simple finger touches. Overall,the IIS integrates the three major functions of smart sports sensing, energy capture, and smart home control, providing important application prospects in the fields of smart sports and human-computer interaction for the disabled.

中国作为全球系统重要性国家,外部环境变化必然冲击国内债券市场,投资者情绪起落传递金融风险.本文选取2007—2022年中国非金融上市公司发行债券数据验证地缘政治风险对企业融资成本的影响.研究发现,此类风险带来的冲击扩大企业债券信用利差,投资者乐观情绪与低违约避险效应缓解了冲击,国有企业债券违约强化负面信息传递,并且企业应对措施因其特性和货币金融环境不同而异,良好的经济基本面是应对地缘政治冲击最有效的平滑器.为增加企业财务韧性,建议宏观上应健全风险预警机制,完善资本市场体系,合理引导预期,同时要加强企业信息披露机制,建立信誉累积的长效机制.
