Proton exchange membrane fuel cells face rapid operation temperature shifts and changes in membrane water content during startup and dynamic operations, which can impede the performance of hybrid maximum power point tracking algorithms, leading to slower tracking speeds, reduced accuracy, and efficiency losses. To tackle the problems of flawed switching logic and inadequate optimization in current hybrid algorithm, this paper introduces an improved hybrid maximum power point tracking algorithm. First, a dual-mode intelligent switching mechanism that employs a power variation increment threshold alongside a fixed iteration count as dual constraints, thereby boosting dynamic switching stability and minimizing false switching risks. Second, an adaptive step-size optimization strategy during the incremental conductance tracking phase to enhance both convergence speed and steady-state accuracy. MATLAB/Simulink simulations for a PEMFC system show that the proposed improved hybrid algorithm reduces dynamic tracking time by 58.88 %–75.42 % under startup and dynamic conditions, increases tracking accuracy by 0.40 %–1.76 %, and ultimately boosts tracking efficiency by 0.96 %–5.50 %. When applied to fuel cell systems, this algorithm can significantly enhance clean power output.

质子交换膜燃料电池在启动和动态运行过程中面临快速的运行温度变化和膜含水量变化，这可能会影响混合最大功率点跟踪算法的性能，导致跟踪速度变慢、精度降低和效率损失。针对当前混合算法存在的切换逻辑缺陷和优化不足的问题，提出了一种改进的混合最大功率点跟踪算法。首先，采用功率变化增量阈值和固定迭代次数作为双重约束的双模智能开关机制，提高了动态开关的稳定性，最大限度地降低了误开关风险。其次，在电导增量跟踪阶段采用自适应步长优化策略，以提高收敛速度和稳态精度。对PEMFC系统的MATLAB/Simulink仿真结果表明，改进的混合算法在启动和动态条件下的动态跟踪时间缩短了58.88% ~ 75.42%，跟踪精度提高了0.40% ~ 1.76%，最终跟踪效率提高了0.96% ~ 5.50%。将该算法应用于燃料电池系统，可显著提高清洁电力输出。

Uncontrolled dendritic growth remains a critical barrier to the practical deployment of lithium metal anodes. While direct current (DC) deposition has been extensively studied, alternating current (AC) and pulsed driving introduce competing timescales—diffusion, double-layer charging, and interfacial kinetics—that fundamentally reshape morphology. Here we present a computational framework that integrates phase-field morphology with transport and kinetic models to systematically map the frequency–amplitude–duty space. High-resolution parametric sweeps quantify signal-space metrics such as phase lag, total harmonic distortion (THD), and concentration stability, linking them to morphological outcomes. Our results reveal high frequency (≥10 Hz), low normalized amplitude (b/v ≤ 0.05), and segmented duty cycles minimize THD and depletion, favoring compact deposition. The global optimum occurs at f = 20 Hz and b/v = 0.025, where THD reaches its minimum (0.1069) alongside robust phase response and concentration stability. These findings provide mechanistic insight and actionable design rules for waveform engineering in lithium systems, offering a quantitative foundation for safer, high-performance lithium-metal batteries.

不受控制的枝晶生长仍然是锂金属阳极实际部署的关键障碍。虽然直流（DC）沉积已经得到了广泛的研究，但交流（AC）和脉冲驱动引入了竞争的时间尺度——扩散、双层充电和界面动力学——从根本上重塑了形貌。在这里，我们提出了一个计算框架，将相场形态学与输运和动力学模型相结合，系统地映射频率-幅度占空空间。高分辨率参数扫描量化信号空间指标，如相位滞后、总谐波失真（THD）和浓度稳定性，并将它们与形态学结果联系起来。我们的研究结果表明，高频（≥10 Hz）、低归一化幅度（b/v≤0.05）和分段占空比将THD和损耗降至最低，有利于致密沉积。全局最优发生在f = 20 Hz和b/v = 0.025时，THD达到最小值（0.1069），并且具有强大的相位响应和浓度稳定性。这些发现为锂系统的波形工程提供了机理见解和可操作的设计规则，为更安全、高性能的锂金属电池提供了定量基础。

Parameter estimation in electrochemical models remains a significant challenge in their application. This study investigates the impact of different operating profiles on electrochemical model parameter estimation to identify the optimal conditions. In particular, the present study is focused on Nickel Manganese Cobalt Oxide(NMC) lithium-ion batteries. Based on five fundamental current profiles (C/5, C/2, 1C, Pulse, DST), 31 combinations of conditions were generated and used for parameter estimation and validation, resulting in 961 evaluation outcomes. The Particle Swarm Optimization is employed for parameter identification in electrochemical models, specifically using the Single Particle Model (SPM). The analysis considered three dimensions: model voltage output error, parameter estimation error, and time cost. Results show that using all five profiles (C/5, C/2, 1C, Pulse, DST) minimizes voltage output error, while C/5, C/2, Pulse, DST minimizes parameter estimation error. The shortest time cost is achieved with 1C. When considering both model voltage output and parameter errors, C/5, C/2, 1C, DST is optimal. For minimizing model voltage output error and time cost, C/2, 1C is best, while 1C is ideal for parameter error and time cost. The comprehensive optimal condition is C/5, C/2, 1C, DST. These findings provide guidance for selecting current conditions tailored to specific needs.

电化学模型的参数估计是其应用中的一个重大挑战。本研究探讨了不同的工作模式对电化学模型参数估计的影响，以确定最佳条件。特别是，目前的研究重点是镍锰钴氧化物（NMC）锂离子电池。基于5个基本电流剖面（C/5、C/2、1C、Pulse、DST），生成31个条件组合用于参数估计和验证，得到961个评价结果。粒子群优化算法用于电化学模型的参数辨识，特别是单粒子模型。分析考虑了三个维度：模型电压输出误差、参数估计误差和时间成本。结果表明，使用C/5、C/2、1C、Pulse、DST五种轮廓线可使电压输出误差最小化，而使用C/5、C/2、Pulse、DST则可使参数估计误差最小化。使用1C的时间成本最短。同时考虑模型电压输出和参数误差，C/5、C/2、1C、DST为最优。为了最小化模型电压输出误差和时间成本，C/2, 1C是最好的，而1C是理想的参数误差和时间成本。综合最优条件为C/5、C/2、1C、DST。这些发现为选择适合具体需要的当前条件提供了指导。

It is a critical challenge for sustainable energy technologies to develop a highly-active non-noble bifunctional catalyst for both electrocatalytic and photoelectrocatalytic water splitting. Herein, an ordered mesoporous CoP has been synthesized by nano-casting method as a bifunctional catalyst for overall water splitting with a low driving voltage of 1.656 V at 10 mA cm⁻² in 1 M KOH electrolyte. A dual-photoelectrodes system has been further constructed by coating of the as-synthesized CoP catalyst on Si-based semiconductors. The composite photocathode and photoanode exhibit photon-to-current efficiencies of 5.16 % and 2.78 % under simulated AM 1.5G irradiation, respectively. A solar-to-hydrogen efficiency of 3.54 % is obtained in a series-structured photoelectrochemical cell. This work provides theoretical guidance for the preparation of mesoporous materials and the construction of dual-photoelectrode system.

Developing a detailed understanding of the ageing evolution in automotive lithium-ion cells is key to batteries with long service life. In this study, the SEI composition and growth rate of graphite negative electrodes from cycle-aged large-format automotive lithium-ion cells is investigated as important parameters in physics-based ageing models. In this work, automotive cells were cycle-aged in a duty cycle protocol with intermittent reference parameter test. The SEI layers formed at different state-of-health were characterized by X-ray photoelectron spectroscopy sputter depth profiling and electron microscopy on electrode cross-sections. The SEI growth over time showed a linear relationship. However, the growth rates derived from the two techniques differed considerably and major differences in SEI thicknesses were found between edge and center regions of electrode sheets. In an attempt to facilitate access to relevant experimentally derived model parameters, a lab-scale setup build from Li-ion cell components from an automotive battery was developed that could reproduce the SEI evolution and growth behavior.

Supply risk of Critical Raw Materials (CRMs) could be an essential bottleneck for further take-off of renewable energy conversion systems such as polymer electrolyte membrane fuel cells (PEMFCs). Here, we validate closed-loop recycling of Pt/C electrocatalyst from a high-temperature PEMFC (HT-PEMFC) stack. Due to their high hydrophobicity, Pt recovery from the HT-PEMFC electrodes poses different challenges compared to those in case of low-temperature PEMFCs; the recovery efficiency can be improved through enhanced mixing and reduced sample size. The Pt/C recycling process involved (i) Pt recovery, (ii) Pt/C synthesis and (iii) its electrocatalytic performance evaluation using half-cell and single cell configurations. The recovery of Pt was realized through a hydrometallurgical approach under mild conditions. Here, the overall Pt recovery efficiency of ∼83 % was achieved. Further, the recovered Pt was used to synthesize Pt/C electrocatalyst, which exhibited electrochemical performances comparable to that of the commercial reference Pt/C in half-cell configuration. Again, MEA with a 50 % recycled Pt/C blended anode shows a HT-PEMFC single cell polarization curve similar to that of a reference MEA, prepared using state-of-the-art Pt/C. The presented work demonstrates a viable route of sustainable material supply for HTPEM technologies and potentially beyond.

Aqueous zinc-ion batteries (AZIBs) have emerged as a compelling research focus due to their high theoretical specific capacity and low redox potential. However, the uncontrolled growth of Zn dendrites and parasitic side reactions persist as pivotal bottlenecks impeding their practical deployment. Herein, a flexible membrane constructed from nano-silver particle-decorated printer paper fabrics (P-Ag) was successfully engineered and implemented as a protective interlayer to mitigate these challenges. In the presence of the P-Ag interlayer, the Zn//Zn symmetric cell demonstrated an extraordinary long-cycle life of 2200 h under the operating conditions of 2 mA cm⁻² and 1 mAh cm⁻². Meanwhile, the Zn//Cu asymmetric cell with the P-Ag interlayer achieved an ultra-prolonged cycling lifespan of 3000 cycles, with a near-100 % average coulombic efficiency (CE) and a minimal voltage hysteresis of ∼92 mV even at a high current density of 10 mA cm⁻². The P-Ag interlayer not only optimize interfacial compatibility but also lower the desolvation energy barrier of hydrated Zn²⁺ and regulate Zn²⁺ homogeneous distribution. Furthermore, acting as a physical barrier, the highly flexible hybrid P-Ag interlayer effectively buffers the volume variation of the Zn metal anode during cycling. This study establishes a viable paradigm for the design of multifunctional interlayers in AZIBs.

水溶液锌离子电池（azib）由于其高理论比容量和低氧化还原电位而成为一个引人注目的研究热点。然而，锌枝晶不受控制的生长和寄生副反应仍然是阻碍其实际应用的关键瓶颈。在此，由纳米银颗粒装饰的打印纸织物（P-Ag）制成的柔性膜被成功设计并实现为保护夹层，以减轻这些挑战。在P-Ag中间层存在的情况下，锌/锌对称电池在2 mA cm - 2和1 mAh cm - 2的工作条件下具有2200 h的超长循环寿命。同时，具有P-Ag中间层的Zn/ Cu不对称电池实现了3000次的超长循环寿命，即使在10 mA cm−2的高电流密度下，平均库仑效率（CE）也接近100%，电压滞后最小为~ 92 mV。P-Ag夹层不仅优化了界面相容性，而且降低了水合Zn2+的脱溶能垒，调节了Zn2+的均匀分布。此外，作为一个物理屏障，高度柔性的P-Ag杂化层有效地缓冲了锌金属阳极在循环过程中的体积变化。本研究为azib中多功能中间层的设计建立了一个可行的范例。

Lithium-sulfur batteries represent one of most attractive energy storage systems due to their high theoretical energy density and the cost-effectiveness of sulfur. However, their commercialization is hampered by issues such as the shuttle effect of lithium polysulfides (LiPSs) intermediates and sluggish electrochemical conversion kinetics. This study reports a conjugated poly(hexaazatrinaphthalene) (PHATN) scaffold coating on polypropylene (PP) separator (PHATN@PP) to address these critical challenges. The PHATN scaffold can trap LiPSs via coordinating interaction between Li⁺ and C=N groups. In addition, the highly conjugated aromatic ring skeleton facilitates the electronic conduction during charge transfer process of LiPSs conversion. Theoretical calculation results and electrochemical analyses reveal that the PHATN scaffold exhibits moderate binding energies towards Li₂S₆ (−1.365 eV) and Li₂S₄ (−1.872 eV) and very low dissociation energy batteries during step-wise conversion of Li₂S₈ to Li₂S. As a result, the assembled Li-S batteries using PHATN@PP separator maintain a satisfactory specific capacity of around 706.6 mA h g⁻¹ after 100 cycles under a sulfur loading of 5 mg cm⁻², which are superior than those with pristine PP separator. This work presents an efficient metal-free azacycle conducting polymer for promising Li-S batteries.

锂硫电池由于其较高的理论能量密度和硫的成本效益而成为最具吸引力的储能系统之一。然而，它们的商业化受到诸如多硫化锂（LiPSs）中间体的穿梭效应和缓慢的电化学转化动力学等问题的阻碍。本研究报告了一种共轭聚（六氮杂萘）（PHATN）支架涂层在聚丙烯（PP）分离器（PHATN@PP）上，以解决这些关键问题。PHATN支架可以通过Li+和C=N基团之间的协调相互作用来捕获lips。此外，高共轭的芳环骨架有利于LiPSs转化过程中电荷转移过程中的电子传导。理论计算结果和电化学分析表明，PHATN支架对Li2S6 （- 1.365 eV）和Li2S4 （- 1.872 eV）的结合能适中，在Li2S8逐步转化为Li2S的过程中解离能很低。结果表明，在含硫量为5 mg cm−2的条件下，使用PHATN@PP隔膜的锂电池在循环100次后仍能保持706.6 mA h g−1左右的比容量，优于使用原始PP隔膜的锂电池。本文提出了一种高效的无金属氮杂环导电聚合物，用于锂硫电池。

This study presents a pioneering investigation into the adverse effects of photointercalation in the context of photoelectrochemical (PEC) properties. In this work, thin films of molybdenum trioxide (MoO₃) and bismuth vanadate (BiVO₄) were prepared using magnetron sputtering and pulsed laser deposition (PLD), respectively. The FTO/BiVO₄/MoO₃ and FTO/MoO₃/BiVO₄ thin film configurations were subsequently annealed at 450 °C for 2 h in an air atmosphere to obtain crystalline phases. The synergistic effects of MoO₃ and BiVO₄ coupling on structural, optical, and photoelectrochemical properties were systematically examined. The FTO/MoO₃/BiVO₄ heterojunction emerged as a promising photoanode, exhibiting a significant enhancement in photocurrent compared to pristine BiVO₄. In contrast, the FTO/BiVO₄/MoO₃ configuration demonstrated a reduction in photocurrent relative to pure BiVO₄. This study provides new insights into the photointercalation of alkali metal cations and its profound impact on photoelectrochemical properties. Furthermore, it explores potential strategies to mitigate or eliminate the detrimental effects of photointercalation, thereby improving the overall photoactivity of the system. This research presents a new approach to tackling the challenges of photointercalation, opening up opportunities for improved photoelectrochemical performance in future applications.

本研究在光电化学（PEC）性质的背景下对光插层的不利影响进行了开创性的研究。本文采用磁控溅射和脉冲激光沉积技术分别制备了三氧化钼（MoO3）和钒酸铋（BiVO4）薄膜。然后将FTO/BiVO4/MoO3和FTO/MoO3/BiVO4薄膜结构在450°C空气气氛中退火2 h，得到结晶相。系统地考察了MoO3和BiVO4偶联对结构、光学和光电化学性能的协同效应。FTO/MoO3/BiVO4异质结是一种很有前途的光阳极，与原始BiVO4相比，其光电流显著增强。相比之下，FTO/BiVO4/MoO3结构显示出相对于纯BiVO4的光电流降低。该研究为碱金属阳离子的光插层及其对光电化学性质的深远影响提供了新的见解。此外，它还探讨了减轻或消除光插层有害影响的潜在策略，从而提高系统的整体光活性。这项研究提出了一种解决光插层挑战的新方法，为未来应用中提高光电化学性能开辟了机会。

As the dominant electrochemical energy storage medium, lithium-ion batteries necessitate high-precision prediction of progressive capacity fade and remaining useful life degradation induced by aging mechanisms. However, generalization capabilities of existing prognostic models are severely constrained by highly dynamic operations, material diversity, and prohibitive costs associated with cross-scenario aging data acquisition. To overcome these limitations, a Memory-Augmented Prototypical Transfer framework is proposed, featuring dual-path coordination wherein anomalous data interference is dynamically suppressed through the noise-aware reweighting module while source-domain aging feature primitives are preserved via the virtual prototype adaptive module, effectively resolving catastrophic forgetting and noise robustness challenges in transfer learning. Implementation achieves 71.84 % mean absolute error reduction in capacity prediction. Module-scale applications utilizing multimodal data fusion attains cell-to-module prognostics with only 150 cycles, attaining mean absolute errors of 11.96 for capacity degradation and 14.18 for remaining useful life estimation. This approach establishes a robust solution for service life health management of complex battery systems under data scarcity constraints, advancing intelligent management technologies for energy storage systems.

锂离子电池作为主要的电化学储能介质，需要对老化机制引起的容量逐渐衰减和剩余使用寿命退化进行高精度预测。然而，现有预测模型的泛化能力受到高度动态操作、材料多样性以及与跨场景老化数据采集相关的高昂成本的严重限制。为了克服这些限制，提出了一种双路径协调的记忆增强原型迁移框架，其中通过噪声感知重加权模块动态抑制异常数据干扰，同时通过虚拟原型自适应模块保留源域老化特征原语，有效解决迁移学习中的灾难性遗忘和噪声鲁棒性挑战。实现后的容量预测平均绝对误差降低了71.84%。利用多模态数据融合的模块级应用仅用150个周期就实现了单元到模块的预测，容量退化的平均绝对误差为11.96，剩余使用寿命估计的平均绝对误差为14.18。该方法为数据稀缺约束下复杂电池系统寿命健康管理提供了鲁棒性解决方案，推动了储能系统智能管理技术的发展。
