Nevertheless, there remains a substantial opportunity for further development in supercapacitor design, particularly when employing binder-type electrode materials. This is due to the presence of interfacial contact resistance, which can compromise the supercapacitor's performance. Additionally, there are instances where the electrode materials fail to adhere completely to the electrode substrate, leading to a decline in the electrochemical performance of the supercapacitor. To address these challenges, a self-healing, all-in-one hydrogel supercapacitor was fabricated via in-situ polymerization of aniline and Zirconium dioxide (ZrO₂) nanocomposites on the surface of self-healing natural rubber-based hydrogel electrolyte. This study introduces ZrO₂ nanoparticles along with polyaniline to enhance the all-in-one supercapacitor's performance, leveraging their exceptional structural, thermal, and electrochemical properties. When subjected to galvanostatic charge-discharge tests, the flexible all-in-one hydrogel supercapacitor displayed impressive areal capacitances, reaching 36.59 mF/cm², 42.59 mF/cm², and 47.62 mF/cm² for PZ0, PZ1, and PZ3 respectively, at a current density of 0.5 mA/cm². Notably, the highest energy density and power density were achieved by PZ3 (containing 0.3 wt% ZrO₂), yielding 144.67 μWh/cm² (at 0.5 mA/cm²) and 1345.10 μW/cm² (at 1 mA/cm²), respectively. Even at higher current densities (1 mA/cm²), the all-in-one hydrogel supercapacitor retained 61.84 % of its initial capacitance. These remarkable electrochemical properties of PZ3 are attributed to the ZrO₂ incorporation, by promoting Faradaic reactions at the electrode.</div></div>","PeriodicalId":15942,"journal":{"name":"Journal of energy storage","volume":"132 ","pages":"Article 117827"},"PeriodicalIF":8.9,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144721194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study systematically investigates the TR behavior of commercial Li (Ni_0.6Co_0.2Mn_0.2) O₂//graphite pouch cells under overcharging conditions at different C-rates (0.5, 0.75, and 1C). Based on the evolution of key parameters, the overcharging process could be divided into four stages, and the electrical and thermal behaviors of each stage are studied. Incremental capacity and differential voltage analysis reveals that overcharging disrupts the lithium-ion transport channels, leading to electrode material degradation and side reactions, which in turn increases the risk of TR. This deduction is confirmed through microscopic and spectroscopic characterizations. Post-mortem analysis reveals that overcharging causes the collapse of the layered cathode structure, the formation of large amounts of lithium deposits on the anode surface, and a reduction in the graphitization degree. To enhance the safety of LIBs, a multi-level early warning strategy is proposed according to the changes in multiple signals, such as maximum temperature difference, crest voltage, and the detection of gas. This study through comprehensive analyses, links electrode degradation to TR risk and innovatively proposes a multi-level early warning strategy with clear thresholds based on the evolution of multiple signals during the overcharging process, alleviating the limitations of existing single signal studies.

Herein, an interfacial composite coating was constructed on the zinc anode. SiO₂ is uniformly dispersed as a secondary network within the polymethyl methacrylate (PMMA) matrix. It enhances the mechanical strength and ionic conductivity of the PMMA framework, promotes the homogeneous deposition of zinc ions (Zn²⁺), and serves as an effective barrier between the anode and the electrolyte, thereby inhibiting the hydrogen evolution reaction (HER) and reducing metal corrosion. The symmetric cell with the modified anode achieves an ultralong cycling lifespan of 2200 h at 3 mA cm⁻², while the full cell demonstrates exceptional rate capability and cycling stability. Furthermore, theoretical calculations elucidate that SiO₂ acts as a “restrictor” by reducing the crystallinity of PMMA and enhancing the movement of chain segments, ultimately facilitating the transfer of Zn²⁺.

This paper proposes a lithium-ion battery RUL prediction based on multi-feature scale health factors and a centralized strategy learning method. It aims to reduce the time complexity of data preprocessing and consider the interaction between data. Firstly, to ensure the richness of the data sequences and its interaction effects, multi-feature scale health factors are extracted from the battery dataset. Secondly, the proposed multi-feature scale star aggregation and redistribution model is adopted. Multiple correlation coefficients were used to analyze the correlation of the extracted data sequences, and then self-adaptive selection was performed. A centralized strategy learning approach was employed to capture inter-sequence dependencies, followed by feature aggregation and redistribution for prediction. Finally, the proposed method was rigorously evaluated on three distinct datasets: the NASA benchmark dataset, the Oxford battery degradation dataset, and our proprietary experimental dataset. Experimental validation demonstrates that the proposed prediction method achieves superior performance, maintaining consistently high coefficients of determination for RUL estimation across all datasets. Compared with other prediction methods, the proposed approach maintains errors below 1.7 %, demonstrating superior accuracy and enhanced generalization capability.</div></div>","PeriodicalId":15942,"journal":{"name":"Journal of energy storage","volume":"132 ","pages":"Article 117875"},"PeriodicalIF":8.9,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144721837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study employs molecular dynamics simulations to quantitatively compare the diffusion behaviors of hydrogen and methane in nanoscale halite slit pores under typical storage conditions. Results reveal that hydrogen exhibits 6.42–12.35 times higher diffusion coefficients than methane. Attributed to hydrogen's weaker van der Waals interactions with halite surfaces, methane adsorption energy is 0.730–1.029 kcal/mol lower and accumulates 1.72–2.23 times more densely near slit pore walls, while hydrogen distributes homogeneously with secondary mid-pore density peaks. Activation energy analysis indicates methane requires 0.424–0.724 kcal/mol higher energy for diffusion. Furthermore, three components of diffusion activation energy are identified: gas-mineral interaction, spatial confinement, and gas-gas interaction. As pore size increases, gas-gas interaction dominates, with hydrogen converging to 0.915 kcal/mol and methane to 1.642 kcal/mol. Notably, hydrogen requires more energy to overcome spatial confinement in slit pores compared to methane, likely due to its smaller molecular diameter.

These Conventional models have progressed significantly in terms of forecasting the initial stages, limitations, and spread of the thermal runaway (TR). However, these models have some drawbacks. Originally, these models were material-specific, assumed breakdown products a priori and failed to forecast rapid heat release above ~450 K. Additionally, the accuracy of sub-models of thermal abuse, such as venting and combustion models, is dependent on decomposition models' ability to predict temperature and gas evolution. This review provides valuable guidance for researchers involved in the development of TR models for LIBs. By highlighting the limitations of existing models and presenting innovative approaches, it offers a roadmap for advancing the state-of-the-art in this field. This review discusses upgraded traditional models and novel approaches that refine and extend prior models for exothermic reactions during TR. In general, there are two primary approaches: legacy modeling employing empirical equations and innovative approaches including thermodynamic and microkinetic approaches, for modeling thermal abuse often known as exothermic reactions. Micro-kinetic modeling enhances modeling skills by predicting flammable gas generation while Thermodynamic models can be employed to quantitatively quantify heat production under a variety of failure conditions, including Li-ion batteries, and solid-state batteries.
