Lithium-ion (Li-ion) batteries are highly efficient for electric vehicles (EVs) but face challenges such as thermal management, risk of thermal runaway, and high costs of lithium and cobalt. Overcoming these challenges is vital for the widespread adoption of hybrid and EVs. To overcome this drawback, this article proposed a large-kernel attention graph convolutional network (LKAGCN) with leaf in wind optimization algorithm (LWOA) named as LKAGCN-LWOA technique, which enhances the thermal management of prismatic Li-ion batteries by integrating both active and passive cooling techniques. The system incorporates phase change materials (PCMs) with porous-filled mini-channels to regulate battery temperature effectively. The LKAGCN analyze thermal properties, battery conditions, and PCM characteristics to predict and optimize the thermal behavior of the battery pack using LWOA. The proposed methods tune the parameters of the hybrid thermal management system, ensuring efficient thermal regulation and improved performance. The proposed method is compared to various existing methods such as convolutional neural network (CNN), Taguchi method, and Finite element model (FEM).</p>\u0000 </div>","PeriodicalId":11765,"journal":{"name":"Energy Storage","volume":"6 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142525037","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}

Our study addresses this need by optimizing the industrial process of liquefied natural gas (LNG) storage, focusing on enhancing thermal performance and energy efficiency. Leveraging a standard LNG storage design, we meticulously evaluated critical supporting variables, modeled key components, and conducted integrated cycle simulations. The primary goal was to minimize the volume of stored gas (achieving a reduction to approximately 1/600th of its gaseous state) while maintaining optimal storage conditions. Our methodology prioritizes insulation over pressure-bearing factors in large-scale tanks, aligning with the unique thermal challenges of LNG storage.

Such a scenario is captured by the respective economies' carbon productivity (CP) scores. Remarkably, it is expected that technological advancements could be harnessed to achieve CP. Hence, many countries have publicly invested in green technologies R&amp;D, including energy efficiency, renewables, nuclear, hydrogen, and energy storage. However, existing studies did not verify the specific contributions of these technological advances to CP, leaving a notable void in the literature. Hence, the current research verified various green technology R&amp;D contributions to CP. Based on panel data from 2003 to 2022, this study implemented the novel instrumental variable quantile regression technique for updated insights. The study uncovers the heterogeneous contributions of each energy innovation variant to the quantile distributions of CP. The heterogeneous effects underscore each country's changing economic structures and varied energy innovation implementation paths. Hence, policy consistency is key to driving CP and ensuring environmental compatibility. R&amp;D on renewable, nuclear, and energy efficiency technologies contributed most significantly to CP across the distributions. R&amp;D on hydrogen and energy storage technologies contributed the least to CP. Therefore, allocating more funds to all R&amp;Ds that boost energy-enhancing technologies for overall environmental sustainability is expedient.

A comparison of the cell voltage characteristics and rate capability of sodium and lithium-ion batteries using different types of electrodes and electrolytes. For sodium-ion batteries electrolytes used are NaPF₆ and NaClO₄ and electrodes used are NaCoO₂, NaNiO₂, NaFePO₄, (Na₃V₂(PO₄)₃), graphite, hard carbon, sodium metal, and sodium titanate.

The heat transfer fluid (HTF) is delivered via a perforated radial pipe placed at the center of the packed bed along the axial length. Hot fluid flows from the center toward the wall through the holes (like other radial systems), but then leaves via the traditional axial flow exit, creating the HRA flow configuration. A computational fluid dynamics (CFD) model is used to analyze the thermal performance of the packed bed during the charging process utilizing the new HRA system. Alumina beads of 6 mm were filler materials and air was HTF with inlet temperature of 75°C for proof of concept. The present paper focuses on two aims: (1) utilizing CFD models to analyze flow and temperature profiles in the packed bed; (2) comparing the model results to experimental results published in a previous HRA flow study and to traditional axial flow. Two HRA configurations were considered based on previous experimental designs, one with uniform holes in the central pipe (R₁) and one with gradients in the hole sizes to promote even flow from the central pipe into the bed (R₂). The numerical results agree with the experimental results in both cases. The HRA system performance depends on the flow profile created by the hole designs, and it can perform better than the axial flow depending on the design of the radial pipe. Design R₂, which promotes even flow from the central pipe into the bed, has higher charging efficiency than standard axial flow methods. For HRA design R₂ at 0.0048 m³/s (7 SCFM, standard cubic feet per minute), numerical results for charging efficiency were 75.5% versus 73.8% for traditional axial flow.
