Traditional battery thermal management systems (BTMS), such as air-based cooling and indirect liquid cooling using cold plates, often result in high thermal gradients—both vertically within cells and horizontally across battery packs—especially under high-current discharge rates. To address these issues, this study introduces and evaluates a steady-state convection-based ester-oil immersion cooling (EOIC) technique for LIBs. Numerical simulations based on the Newman, Tiedemann, Gu and Kim model, aligned with multi-scale multi-dimensional principles, were performed on both a single 18650 cylindrical cell and a 4S2P battery pack. Experimental validations were conducted under 2C and 3C discharge rates at 25°C ambient temperature. The EOIC system demonstrated a temperature reduction of up to 13°C in the 18650 cell and 15°C in the 4S2P pack at 3C discharge compared to natural air convection and achieved ≤ 10°C thermal gradient across cells in the battery pack. The simulation results closely matched experimental data, with a maximum deviation of only 2°C, confirming the model's reliability. Moreover, EOIC outperformed conventional mineral oil-based immersion cooling in both cooling effectiveness and temperature uniformity. These findings confirm EOIC as a promising passive BTMS approach, ensuring improved safety, performance, and thermal stability for LIBs in electric vehicle applications.</p>\u0000 </div>","PeriodicalId":11765,"journal":{"name":"Energy Storage","volume":"7 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144074635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the high cost of installing wind Turbine (WT), MT, PV panels, and Energy Storage Systems (ESS), along with the necessary infrastructure, makes it a costly solution, particularly for small-scale or residential applications. To address these challenges, this paper proposes a hybrid approach for the economic assessment of a grid-connected hybrid Wind-MT-PV-EV system. The proposed method combines the Sand Cat Swarm Optimization (SCSO) algorithm with the Attention-Based Sparse Graph Convolutional Neural Network (ASGCNN), forming the SCSO-ASGCNN technique. The goal is to enhance the economic performance, cost-effectiveness, and dynamic control of the hybrid system. The SCSO algorithm is employed to optimize energy management (EM) and improve the operational efficiency of the system, while the ASGCNN is utilized to predict the forecast patterns of energy generation and consumption. The proposed method is implemented on the MATLAB platform and evaluated against several existing approaches, including the Adaptive Genetic Algorithm (AGA), Proximal Policy Optimization (PPO), State-Action-Reward-State-Action (SARSA), Deep Reinforcement Learning (DRL), and Modified Dragonfly Algorithm (MDA). The results show that the SCSO-ASGCNN method achieves the lowest average cost of $532.63, demonstrating its superior performance in minimizing costs compared to other methods.</p>\u0000 </div>","PeriodicalId":11765,"journal":{"name":"Energy Storage","volume":"7 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143944513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although limited research has been explored on the oxidation of butanol compared to that of methanol and ethanol. In the present work, a bimetallic organic framework (CoZn-MOF) was employed to disperse Pd nanoparticles and was utilized for the first time for butanol oxidation in basic media. The CoZn-MOF was synthesized through the coprecipitation method, followed by electrodeposition of Pd nanoparticles onto the nanocomposite. The as-prepared catalyst material was characterized by SEM, EDS, XRD, and FT-IR analysis. Electrochemical analysis, including cyclic voltammetry (CV), electrochemical impedance spectroscopy, and chronoamperometric studies, revealed that the Pd@CoZn-MOF/GCE showed outstanding electrocatalytic performance, higher current density (0.01895 A cm<sup>−2</sup>), excellent stability (350 cycles) and durability (3000 s), and strong resistance to catalytic poisoning from carbonaceous species during butanol electro-oxidation, which is due to the effective synergy between CoZn-MOF and Pd nanoparticles, which enhances electron transfer.
