The development of flexible supercapacitors(FSCs) capable of operating at high temperatures is crucial for expanding the application areas and operating conditions of supercapacitors. Gel polymer electrolytes and electrode materials stand as two key components that significantly impact the efficacy of hightemperature-tolerant FSCs(HT-FSCs). They should not only exhibit high electrochemical performance and excellent flexibility, but also withstand intense thermal stress. Considerable efforts have been devoted to enhancing their thermal stability while maintaining high electrochemical and mechanical performance. In this review, the fundamentals of HT-FSCs are outlined. A comprehensive overview of state-of-the-art progress and achievements in HT-FSCs, with a focus on thermally stable gel polymer electrolytes and electrode materials is provided. Finally, challenges and future perspectives regarding HT-FSCs are discussed, alongside strategies for elevating operational temperatures and *** review offers both theoretical foundations and practical guidelines for designing and manufacturing HT-FSCs, further promoting their widespread adoption across diverse fields.

Design and characterization study of dual D-shaped no-core fiber based SPR sensor for refractive index and temperature measurement

引用

Optoelectronics Letters 2025年

作者： Liu Yinggang Li Rui Li Fei Xu xinyi Zhou Rui Shaanxi Engineering Research Center of Oil and Gas Resource Optical Fiber Detection & Shaanxi Key Laboratory of Measurement and Control Technology for Oil and Gas wells， Xi'an Shiyou University

To address the issue of temperature cross-sensitivity in refractive index （RI） measurement， a fiber-optic Surface Plasmon Resonance （SPR） sensor based on dual D-shaped no-core fiber （NCF） is proposed and designed. The sensor mainly consists of D-shaped NCF， Ag/Fe2O3composite film， and polydimethylsiloxane （PDMS）， where the silver and Fe2O3are successively coated on both D-shaped surfaces of NCF to generate SPR and enhance the oxidation resistance. The layer of PDMS coated on one D-shaped surface acts as a tunable ambient medium sensing the temperature variation and affecting the transmission spectrum of the sensor. Since the surface plasmon waves are excited in the two D-shaped surfaces with different films， the two RI and temperature-dependent spectral resonance peaks with different wavelengths will be produced. Research results demonstrate that the two peaks’ wavelengths have different responses to the variations of ambient RI and temperature. In the refractive index range of 1.36-1.376 and temperature range of 10-100 °C， the RI and temperature sensitivities reach to 5000 nm/RIU and -0.546 nm/°C， respectively. With the sensitivity coefficient matrix， simultaneous measurement of refractive index and temperature can be realized， and the corresponding accuracy is superior to 0.4×10-5RIU and 0.037°C.

藻类是一种特殊生物污秽,其在电气设备绝缘子表面附着会使绝缘子耐污闪能力大幅下降,给电网安全稳定运行带来威胁。本文提出了一种融合多尺度卷积注意力机制的绝缘藻类语义分割算法。首先在基础U-Net网络模型上构建了一种用于绝缘藻类等级语义分割的模型,并采用VGG16作为主干特征提取网络。模型采用U型结构,左侧为VGG16及主干特征提取部分,能够有效提取5个特征层信息;右侧为加强特征提取部分。注意力模块选取CBAM模块,并在其基础上引入多尺度卷积;随后在U-Net网络的编码器和解码器进行上采样与下采样之前均加入CBAM卷积注意力模块。最后将本文模型在自行构建的藻类覆盖绝缘子图像数据集上与Deeplabv3+与Transfuse网络进行对比。结果表明:相比于基础U-Net模型,本文模型mIoU值提高了0.28,mPA值提高了0.27,Dice系数提高了0.06,豪斯多夫距离降低了11.77,RVE值降低了0.06。分割过程可视化结果展示了本文模型能更好地关注藻类覆盖区域,且对藻类覆盖区域边界的定位更准确,有效减小了分割误差。

Power and Voltage Control Based on DC Offset Injection for Bipolar Low-voltage DC Distribution System

引用

Journal of Modern Power Systems and Clean Energy 2023年第5期11卷 1529-1539页

作者： xinyi Kong Jianwen Zhang Jianqiao Zhou Jiajie zang Jiacheng Wang Gang Shi Xu Cai key Laboratory of Control of Power Transmission and Conversion of Ministry of Education Department of Electrical EngineeringShanghai Jiao Tong UniversityShanghai 200240China School of Electronic and Electrical Engineering Shanghai University of Engineering ScienceShanghaiChina School of Mechatronic Systems Engineering Simon Fraser UniversitySurreyBCCanada

The bipolar low-voltage DC(LVDC) distribution system has become a prospective solution to better integration of renewables and improvement of system efficiency and reliability. However, it also faces the challenge of power and voltage imbalance between two poles. To solve this problem, an interface converter with bipolar asymmetrical operating capabilities is applied in this paper. The steady-state models of the bipolar LVDC distribution system equipped with this interface converter in the gridconnected mode and off-grid mode are analyzed. A control scheme based on DC offset injection at the secondary side of the interface converter is proposed, enabling the bipolar LVDC distribution system to realize the unbalanced power transfer between two poles in the grid-connected mode and maintain the inherentpole voltage balance in the off-grid mode. Furthermore, this paper also proposes a primary-side DC offset injection control scheme according to the analysis of the magnetic circuit model, which can eliminate the DC bias flux caused by the secondaryside DC offset. Thereby, the potential core magnetic saturation and overcurrent issues can be prevented, ensuring the safety of the interface converter and distribution system. Detailed simulations based on the proposed control scheme are conducted to validate the function of power and voltage balance under the operation conditions of different DC loads.
