However, efficacious water electrolysis for hydrogen production is highly dependent on efficient and stable electrocatalysts. Traditional powder catalysts have defects such as severe particle aggregation, poor conductivity, and weak substrate adhesion. Self-supporting electrodes grown in situ on conductive substrates as electrocatalysts could avoid these problems and therefore exhibit high catalytic activity and stability. Herein, one-dimensional RuO<sub>2</sub> nanorods (NRs) were grown on top of WO<sub>3</sub> nanotube arrays (NTA) through a facile solution impregnation method followed by a high-temperature calcination. The obtained self-supported RuO<sub>2</sub> NRs/WO<sub>3</sub> NTA electrode demonstrates a superb electrocatalytic activity toward hydrogen evolution reaction (HER) in both basic and acidic media. To achieve a current density of 10 mA cm<sup>−2</sup>, the required overpotentials are 33 mV in 1 M KOH and 62 mV in 0.5 M H<sub>2</sub>SO<sub>4</sub>, respectively. Furthermore, RuO<sub>2</sub> NRs/WO<sub>3</sub> NTA also shows excellent long-term electrochemical stability for continuous hydrogen generation over 50 h in both basic and acidic electrolytes. The superb HER activity of RuO<sub>2</sub> NRs/WO<sub>3</sub> NTA could be attributed to the structural merits including large surface area of RuO<sub>2</sub> with abundant catalytically active sites, specific charge transport channel ensuring enhanced reaction kinetics, and abundant open space between RuO<sub>2</sub> nanorods favorable for fast mass transfer and electrolyte accessibility. The present work sheds new light on designing novel one-dimensional composite structures as highly efficient electrocatalyst for sustainable hydrogen generation. Simultaneously, the designed nanorod/nanotube array composite structure in this work is also expected to be applied in other energy conversion devices.</p></div>","PeriodicalId":599,"journal":{"name":"Ionics","volume":"31 7","pages":"7205 - 7216"},"PeriodicalIF":2.6,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145171028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accurate estimation of their remaining useful life (RUL) is essential for enhancing system reliability, optimizing maintenance strategies, and minimizing costs. In this work, battery degradation is inferred from voltage signal behavior, which serves as a reliable non-invasive indicator of aging. We propose a novel model called Weibull Distribution-Informed Neural Network (WDINN), which integrates the probabilistic characteristics of the Weibull distribution into a physics-informed deep learning framework. This approach addresses both the non-linear and stochastic nature of battery degradation. To train and validate the model, degradation profiles were extracted from aging datasets and reference performance testing (RPT) data. The WDINN model demonstrated superior performance compared to several state-of-the-art models, including Bi-LSTM, GRU, and ANN. It achieved an RMSE of 0.00027 ± 0.00003 on the aging dataset. Cluster-based evaluation further revealed that WDINN performs particularly well in scenarios of slow, long-term degradation (e.g., Cluster 0), achieving a test loss of 0.00018 ± 0.00001, while maintaining robustness across more variable short-term degradation patterns in the RPT data.

This work introduces an innovative approach integrating activation, pickling, and carbonization, utilizing Malabar spinach as the carbon precursor and KOH as the activating agent for biochar-based supercapacitors. The activation process enhances the material porosity, while pickling removes the majority of non-carbon elements. Subsequent re-carbonization increases the specific surface area and porosity of carbons, resulting in a higher specific capacitance. The optimized carbons exhibit a high specific surface area (1195.37 m<sup>2</sup> g<sup>−1</sup>), hierarchical porous structure, and remarkable specific capacitance (427.5 F g<sup>−1</sup> at 0.5 A g<sup>−1</sup>). After 10,000 galvanostatic charge/discharge cycles at 10 A g<sup>−1</sup>, the capacitance retention rate remains at 98.71% with a high Coulombic efficiency of 99.67%.

This paper proposes a novel safe and fast charging control strategy for lithium-ion batteries based on deep reinforcement learning, capable of adapting to dynamic changes in the charging environment. Firstly, a unilateral sampling soft actor-critic (USSAC) algorithm is proposed and integrated with an electrochemical-thermal coupling model to train an agent capable of optimizing charging speeds while adhering to multiphysical constraints. The trained agent can then provide a safe and fast charging control strategy and be updated online. Secondly, an adaptive negative pulse regulation method that autonomously adds negative pulses base on multiphysical constraints is proposed to further enhance the safety of the charging process. Finally, the proposed charging strategy is simulated and experimentally verified under different environment conditions. The experimental results show that, compared to the commonly used fast charging strategies, the proposed USSAC-based charging strategy can dynamically provide the optimal charging current in real-time according to the battery environment and its own status, effectively mitigating the risks of overcharge, lithium plating, and thermal hazards.</p></div>","PeriodicalId":599,"journal":{"name":"Ionics","volume":"31 7","pages":"6865 - 6888"},"PeriodicalIF":2.6,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145171573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The incorporation of heteroatoms into hard carbon materials brings about remarkable improvements in their electrochemical performance.

In this study, a simple impregnation doping and two-step carbonization process was employed to prepare N/B/F co-doped hard carbon using <i>Metaplexis japonica</i> tomentum as a precursor and 1-butyl-3-methylimidazole tetrafluoroborate ionic liquid as the dopant source.
