Timely detection of ISC faults at their early stage can effectively prevent severe safety incidents, thereby ensuring the safe and stable operation of battery energy storage systems. To address this challenge, this study proposes a novel early ISC identification method for lithium-ion battery packs based on dynamic time warping (DTW) sequences and Gaussian mixture model (GMM) clustering. First, the median terminal voltage curve is derived from sorted terminal voltage measurements, serving as a reference representing the normal state of cells within the battery pack. Subsequently, sliding time windows are applied to extract subsequences of the median terminal voltage and individual cell terminal voltages. On this basis, the DTW sequences of each cell are computed and utilized as an indicator to characterize abnormal battery behavior, thereby amplifying the discrepancy between early ISC-affected cells and normal ones. Furthermore, an automatic early ISC fault detection model is developed using a GMM-based clustering algorithm to distinguish between normal and early ISC cells within the battery pack. Experimental validation and analysis under various early ISC fault scenarios with different severity levels demonstrate that the proposed method achieves accurate identification of early ISC cells when the short-circuit resistance is less than or equal to1000 Ω.</div></div>","PeriodicalId":13872,"journal":{"name":"International Journal of Electrochemical Science","volume":"20 10","pages":"Article 101107"},"PeriodicalIF":1.3,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144549963","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}

However, prolonged use can result in corrosion failure. To address the corrosion failure of 7A09 aluminum alloy in propylene glycol coolant, this study systematically investigates the synergistic effects of temperature (50–80 ℃), pH value (4–9), and Cl^- concentration (30–90 mg/L) on the corrosion behavior of the aluminum alloy. A comprehensive approach was employed, integrating corrosion testing, electrochemical polarization curve measurements, surface morphology characterization via scanning electron microscopy, and surface composition analysis using X-ray photoelectron spectroscopy (XPS). The results showed that increasing temperature promotes the thermal oxidation of propylene glycol, resulting in the generation of organic acids and an exponential increase in the corrosion rate (I_corr reached 3040 nA cm⁻² at 80 ℃). Elevated Cl^- concentration significantly enhances the sensitivity of the passivation film pitting, with the corrosion current density rising by 24.3 times under 90 mg/L compared to the 30 mg/L conditions. A strongly acidic environment with pH= 4 induces acidic dissolution of the oxide film, whereas, under near-neutral conditions (pH=6–8), the aluminum passivation film synergizes with the Al₂O₃ oxide film to effectively reduce the corrosion rate. XPS analysis further confirmed that Cl^- attacks the C-O bond in propylene glycol molecules, leading to the formation of C-Cl compounds, which compromises the integrity of the protective film and accelerates localized pitting processes.</div></div>","PeriodicalId":13872,"journal":{"name":"International Journal of Electrochemical Science","volume":"20 9","pages":"Article 101105"},"PeriodicalIF":1.3,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144470712","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}

Zinc electroplating, a well-established technique to protect MS, involves the deposition of a thin layer of zinc onto a metal substrate. This forms a corrosion-resistant zinc coating. In this study, natural phenolic extracts from <em>Beta vulgaris</em> L., specifically methanolic (ME), dichloromethane (MDE), ethyl acetate (EAE), and <em>n</em>-butanol (BE) extracts, were analyzed via HPLC-DAD and utilized as eco-friendly additives in zinc electroplating baths composed of ZnCl₂, KCl, and H₃BO₄, to improve the quality and corrosion resistance of zinc coatings on MS. Incorporation of these extracts into the plating bath significantly improved the quality of zinc deposits. The enhanced brightness and refined surface morphology observed through scanning electron microscopy (SEM) and profilometry not only indicate the enhanced quality of the coatings but also suggest potential applications in industries where aesthetics and surface finish are important. Gravimetric corrosion tests and electrochemical evaluations, including potentiodynamic polarization (PP) and electrochemical impedance spectroscopy (EIS), demonstrated that zinc coatings formed in the presence of Beta vulgaris L. extracts exhibited remarkable corrosion resistance compared to conventional coatings. In addition, density functional theory (DFT)-based calculations were performed to investigate the adsorption behavior and chemical reactivity of the main phenolic compounds identified. Theoretical results revealed that ellagic acid exhibits the highest chemical activity, highlighting its key role in improving deposition efficiency and corrosion protection. This research underscores the potential of <em>Beta vulgaris</em> L. phenolic extracts as sustainable, natural additives for enhancing zinc electroplating processes.

Model-based SOC estimation supply an effective solution to computation efficiency, but its accuracy highly dependent on model parameters. Three key technical contributions are made. First, the traditional model parameter identification method based on recursive least squares with forgetting factor (FFRLS) often sets its forgetting factor to be a constant during the iterative process, while disregarding estimated voltage accuracy. In this study, an adaptive forgetting factor recursive least squares method (AFFRLS) is proposed based on the adaptive theory. The core idea is that the forgetting factor is adaptively adjusted according to preset adaptive formula of the voltage error. In this way, both robustness and identification accuracy of the algorithm can be improved effectively. Second, a multi-innovation adaptive unscented Kalman filter (MIAUKF) is proposed to utilize historical voltage data and weaken the impact of voltage cumulative error on SOC accuracy. Finally, the performance of the proposed approach is evaluated by comparison simulations considering three different temperature scenarios based on two standard driving cycles.

However, existing methods generally rely on numerous feature parameters while underutilizing the potential of historical sample data. Additionally, in the early stages of RUL, the weak correlation between capacity and historical samples often compromises prediction accuracy. To address these challenges, this paper proposes a novel prediction framework, DDSF-QD (Dynamic Double Similarity Fusion model incorporating ΔQ Power Law and Dynamic Time Warping). First, the original data are denoised using the CFK method (CEEMDAN-Fuzzy Entropy-K-means) to improve data quality. Then, the proposed ΔQ(V) power law is constructed to evaluate lifetime similarity, and combined with the DTW (Dynamic Time Warping) algorithm to calculate the initial spatial similarity. High-quality historical samples are used to train the network, and then their corresponding weights are dynamically fused within the DDSF (Dynamic Double Similarity Fusion model) framework to update sample weights. This enables the prediction network to estimate future capacity degradation trends and predict RUL based on a predefined failure threshold. Experimental results on classical lithium-ion battery aging datasets demonstrate the superior performance of the proposed method, achieving a coefficient of determination (R²) of 99.85 %. To the best of our knowledge, both the ΔQ(V) power law and the DDSF framework are proposed for the first time, highlighting their potential in battery health management.</div></div>","PeriodicalId":13872,"journal":{"name":"International Journal of Electrochemical Science","volume":"20 10","pages":"Article 101102"},"PeriodicalIF":1.3,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144549955","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}

Compared to sandblasting, grinding, and other surface treatment methods for such complex applications, electrochemical polishing offers the advantages of non-contact processing and uniform treatment; consequently, it has become a key surface treatment technique for cardiovascular stents. To further clarify the overall influence of electrochemical polishing on the service performance of cardiovascular stents, this study investigates the effects of electrochemical polishing parameters, such as the current density, electrode spacing, polishing temperature, and polishing time, on the surface performance of Ni–Ti alloy cardiovascular stents.

The results reveal that electrochemical polishing effectively reduces the surface roughness of the stent, eliminates defects such as thermal damage remaining after laser cutting, and improves the surface quality.
