With the increasing use of silicon-based materials in commercial lithium-ion batteries, the structural design of electrodes has become crucial, necessitating advanced electrode models. Due to the significant electrochemo-mechanical effects from the large volumetric deformation of silicon-based materials, a multiscale electrochemo-mechanical electrode model is essential. In our previous study (Electrochimica Acta, 475 (2024)), we proposed such a model based on the Pseudo-two-dimensional framework developed by John Newman's group. This work utilizes the electrode model as a design tool, exploring three key parameters at the material, electrode, and cell levels: Young's modulus of the binder, the initial porosity of the electrode, and the case pressure. By comparing the predicted rate performance and the reaction and deformation distributions within the electrode under different designs, we offer three recommendations: (a) use a binder with high elasticity that effectively binds with the electroactive materials; (b) ensure the porosity of the pristine silicon-based electrode exceeds 0.6, nearly double that of graphite electrodes, and consider a porosity-graded design; (c) apply an external pressure of approximately 0.25 MPa to the electrode, which preserves structural integrity without harming rate performance.

随着商用锂离子电池越来越多地使用硅基材料，电极的结构设计变得至关重要，这就需要先进的电极模型。由于硅基材料的大体积变形会产生显著的电化学机械效应，因此多尺度电化学机械电极模型至关重要。在我们之前的研究（Electrochimica Acta, 475 (2024)）中，我们基于约翰-纽曼（John Newman）小组开发的伪二维框架提出了这样一个模型。这项研究利用电极模型作为设计工具，探索了材料、电极和电池层面的三个关键参数：粘合剂的杨氏模量、电极的初始孔隙率和外壳压力。通过比较不同设计下的预测速率性能以及电极内部的反应和变形分布，我们提出了三项建议：（a）使用能与电活性材料有效结合的高弹性粘合剂；（b）确保原始硅基电极的孔隙率超过 0.6，几乎是石墨电极的两倍，并考虑采用孔隙率分级设计；（c）对电极施加约 0.25 兆帕的外部压力，这样既能保持结构的完整性，又不会损害速率性能。

Absorption thermal energy storage (TES) is recognized as a promising technology utilizing renewable energy and balancing supply and demand. Thermodynamic analysis of the absorption TES cycle indicates that extending the concentration glide can enhance energy storage density (ESD). However, in real operation, a large concentration glide can increase the risk of crystallization at high concentrations. Additionally, inefficient heat and mass transfer can limit its high ESD potential. In this paper, a closed absorption TES system with novel heat exchangers was established. The plate heat exchangers with narrow and wide channels were used as the generator/absorber and condenser/evaporator. LiCl solution was used as the base working fluid with ethylene glycol (EG) as an additive to extend the concentration glide. The mass ratios of LiCl solutions to EG were 100:0, 100:2.5 and 100:5, respectively. Charging temperatures ranging from 65 to 85 °C were used to represent the solar heat with different temperature levels. The discharging tests were conducted in three modes: heating at 50 °C, combined heating at 40 °C and cooling at 20 °C, and cooling at 10 °C. The experimental results revealed the dynamic characteristics and energy storage performance of the charging and discharging processes. With the addition of EG, the maximum concentration of LiCl solution was increased from 46.7 % to 49 %. The ESD was significantly improved by 18 %–48 %, reaching 123 kWh/m³, 177 kWh/m³, and 108 kWh/m³ in heating, combined heating and cooling, and cooling modes, respectively. These are the highest values recorded for the closed single-stage absorption TES systems to date. The experiments confirmed the effectiveness of EG as an additive for LiCl solution and provided insights for further research.

吸收式热能储存（TES）被认为是一种利用可再生能源和平衡供需的前景广阔的技术。对吸收式热能储存（TES）循环的热力学分析表明，延长浓度滑移可提高能量储存密度（ESD）。然而，在实际运行中，较大的浓度滑动会增加高浓度结晶的风险。此外，低效的传热和传质也会限制其较高的 ESD 潜力。本文建立了一个采用新型热交换器的封闭吸收式 TES 系统。具有窄和宽通道的板式热交换器被用作发生器/吸收器和冷凝器/蒸发器。以氯化锂溶液为基础工作液，乙二醇（EG）为添加剂，以延长浓度滑移。氯化锂溶液与 EG 的质量比分别为 100:0、100:2.5 和 100:5。充电温度为 65 至 85 °C，以表示不同温度水平的太阳热。放电试验在三种模式下进行：50 ℃加热、40 ℃加热和 20 ℃冷却相结合以及 10 ℃冷却。实验结果揭示了充放电过程的动态特性和储能性能。加入 EG 后，氯化锂溶液的最大浓度从 46.7% 提高到 49%。在加热、组合加热和冷却以及冷却模式下，ESD 明显提高了 18%-48%，分别达到 123 kWh/m3、177 kWh/m3 和 108 kWh/m3。这是迄今为止封闭式单级吸收式热电联供系统的最高值。实验证实了 EG 作为氯化锂溶液添加剂的有效性，并为进一步研究提供了启示。

Compressed Air Energy Storage (CAES) is a highly promising technology. This paper focuses on the detailed optimization design of axial compressors with bionic-wavy leading edges for CAES systems, aiming to enhance the safety and economic efficiency of the system. Using low-speed wind tunnel cascade experiments, five-hole probe sweep measurements, and oil flow visualization methods, the study validates the aerodynamic performance improvements of the new bionic-wavy leading-edge design for compressor cascades and analyzes the secondary flow mechanisms within the cascades. The results indicate that the bionic wavy leading edge significantly reduces total pressure loss across an incidence angle range of −24° to 4°, with a maximum loss reduction of 31.3 %, which is over three times the improvement observed in existing studies. Furthermore, this biomimetic design achieves favorable performance over a wider range of incidence angles compared to previous studies. The research reveals the mechanisms of action for the bionic-wavy leading edge at different incidence angles: it alleviates large-scale backflow on the suction surface at positive incidence angles and reduces near‑leading-edge backflow and pressure surface corner separation at negative incidence angles. These findings provide valuable guidance for the design of advanced compressors.

压缩空气储能（CAES）是一项极具前景的技术。本文重点研究了用于 CAES 系统的具有仿生波浪形前缘的轴向压缩机的详细优化设计，旨在提高系统的安全性和经济效益。研究采用低速风洞级联实验、五孔探头扫描测量和油流可视化方法，验证了新型仿生波浪形前缘设计对压缩机级联气动性能的改善，并分析了级联内的二次流动机制。结果表明，仿生波浪形前缘在入射角-24°到4°范围内显著降低了总压力损失，最大损失降低了31.3%，是现有研究中观察到的改善效果的三倍多。此外，与之前的研究相比，这种生物仿生设计在更大的入射角范围内都取得了良好的性能。研究揭示了仿生波浪形前缘在不同入射角下的作用机制：在正入射角下，它能减轻吸力面上的大规模回流；在负入射角下，它能减少近前缘回流和压力面角分离。这些发现为先进压缩机的设计提供了宝贵的指导。

A heterogeneous energy storage system (HESS) is implemented to combat the DC bus voltage instability and power allocation problem caused by high penetration of renewable energy sources (RESs) in a standalone DC microgrid. The HESS comprises a battery and supercapacitor aims to smooth DC bus voltage. Thus, a potent ongoing trend is the development of intelligent power management strategies (PMS) that boost the efficacy of RESs-based DC microgrids using deep reinforcement learning (DRL) techniques. In particular, long short-term memory (LSTM) is incorporated into a deep deterministic policy gradient (DDPG) framework to tackle real-world microgrid power management problems. This method uses DDPG for power allocation decisions, while LSTM is applied to extract environmental state variables from observations. Implementing an LSTM-DDPG PMS quantifies transient performance and minimises voltage deviations from the rated DC bus voltage while maintaining battery and supercapacitor state of charge (SOC) within defined limits to prevent overcharging and excessive discharging cycles. Furthermore, the HESS’s power flow is dynamically regulated by optimal current controllers, which facilitates efficient PMS and enhances overall system stability by precisely tracing respective currents. The effectiveness of the proposed PMS is assessed under different solar, wind, and load power situations. The simulation results demonstrate a substantial decrease in highest disparities of the DC bus voltage compared to traditional PMS approaches. The suggested technique is confirmed effective by real-time validation of the simulation outcomes with the OPAL-RT real-time simulator.

为解决独立直流微电网中可再生能源（RES）的高渗透率造成的直流母线电压不稳定和功率分配问题，采用了一种异构储能系统（HESS）。HESS 由电池和超级电容器组成，旨在平滑直流母线电压。因此，目前一个有力的趋势是开发智能电力管理策略（PMS），利用深度强化学习（DRL）技术提高基于可再生能源的直流微电网的效率。其中，长短期记忆（LSTM）被纳入深度确定性策略梯度（DDPG）框架，以解决现实世界中的微电网电力管理问题。该方法使用 DDPG 进行电力分配决策，同时应用 LSTM 从观测结果中提取环境状态变量。实施 LSTM-DDPG PMS 可以量化瞬态性能，最大限度地减少电压与额定直流母线电压的偏差，同时将电池和超级电容器的充电状态 (SOC) 保持在规定的范围内，防止过度充电和过度放电。此外，HESS 的功率流由最佳电流控制器进行动态调节，这有助于实现高效的 PMS，并通过精确跟踪各自的电流来增强整个系统的稳定性。在不同的太阳能、风能和负载功率情况下，对所提出的 PMS 的有效性进行了评估。仿真结果表明，与传统的 PMS 方法相比，直流母线电压的最高差异大幅减少。通过使用 OPAL-RT 实时模拟器对模拟结果进行实时验证，证实了所建议技术的有效性。

Recent interest in pseudocapacitive materials faces challenges like degradation and high costs, while low-cost carbon materials suffer from low capacitance. SiO₂-GO composites, despite their potential, remain unexplored for pseudocapacitors. The present study addresses this gap by focusing on the synthesis and characterization of SiO₂-GO composites, both in their pure form and doped with NiO and/or CuO. These materials are subsequently investigated for their suitability as electrode materials in supercapacitor applications. The obtained results have been comprehensively analyzed with respect to the bonding interactions and morphological characteristics of each material variant. This analysis aims to elucidate how the incorporation of NiO and/or CuO influences the structural integrity, surface chemistry, and electrochemical performance of the SiO₂-GO composites. By investigating these aspects, we aim to contribute new insights that could lead to the development of efficient and cost-effective pseudocapacitive electrode materials.

The interface interaction between electrodes and electrolytes is a key issue in constructing the integrated supercapacitors. This review focuses on hydrogel bonding interface-induced all-in-one supercapacitors which are assembled by establishing dynamic chemical bonding between the electrode/hydrogel electrolyte interface. This review summarizes the electrolytes based on crosslinking hydrogels. The crosslinking hydrogel is a 3D mesh structure with hydrophilic polymer chains entangled by crosslinking with each other, including single-component crosslinking hydrogels and dual-component crosslinking hydrogels. The abundant functional groups inside the hydrogel not only make the polymer chains more tightly winding but also facilitate the interfacial connection of the electrode/hydrogel electrolyte. The electrode/hydrogel electrolyte interface establishes dynamic chemical bonding by utilizing these functional groups to quickly restore the original structure and maintain electrochemical stability under mechanical deformation. Chemical bonding includes hydrogen bonding, borate bonding, and metal coordination bonding. This is followed by a brief introduction to the application of hydrogel bonding interface-induced all-in-one supercapacitors in the field of wearable electronics devices for flexible energy storage. Finally, the challenges facing the future development of hydrogel bonding interface-induced all-in-one supercapacitors as flexible energy-storage devices are briefly discussed.

This review focuses on hydrogel bonding interface-induced all-in-one supercapacitors which are assembled by establishing dynamic chemical bonding between the electrode/hydrogel electrolyte interface. This review summarizes the electrolytes based on crosslinking hydrogels. The crosslinking hydrogel is a 3D mesh structure with hydrophilic polymer chains entangled by crosslinking with each other, including single-component crosslinking hydrogels and dual-component crosslinking hydrogels. The abundant functional groups inside the hydrogel not only make the polymer chains more tightly winding but also facilitate the interfacial connection of the electrode/hydrogel electrolyte. The electrode/hydrogel electrolyte interface establishes dynamic chemical bonding by utilizing these functional groups to quickly restore the original structure and maintain electrochemical stability under mechanical deformation. Chemical bonding includes hydrogen bonding, borate bonding, and metal coordination bonding. This is followed by a brief introduction to the application of hydrogel bonding interface-induced all-in-one supercapacitors in the field of wearable electronics devices for flexible energy storage.
