This necessitates the regulation on temperatures through effective thermal management. The present study evaluates a battery thermal management system (BTMS), viz. a serpentine and L-shaped mini-channel cold plates using nanofluid coolant combined with phase change material (PCM) subjected to a constant discharge of 80 A (8 C) and US06 drive schedule. A 4S4P LIB module rated 0.147 kWh, consisting of cylindrical cells, was chosen for the investigation. The thermal and electrical governing equations of the MSMD battery module were numerically solved using ANSYS Fluent solver. It is observed that a laminar flow at a Reynolds number of 1380 with the Al₂O₃ nanofluid having concentration in the range of 0.02–0.035 is effective in achieving lower battery surface temperatures and decreased pumping losses. The serpentine cold plate with the PCM effectively dissipated nearly 91% of the generated heat, but it experienced a 50% higher pressure drop compared to the L-shaped configuration. The study emphasizes that both the heat dissipation and the pressure loss in the cooling system play a vital role in the design and choice of BTM.</p>\u0000 </div>","PeriodicalId":11765,"journal":{"name":"Energy Storage","volume":"7 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144885325","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}

In this work, carbon collected from rice bran oil burning, termed nanocarbon (NC) and its activated form (ANC), is well characterized for structure, morphology, and electrochemical properties, to assess their potential use in supercapacitor applications. The performance of the supercapacitors, fabricated using NC, ANC, and a commercial carbon (CC) as electrode material, has been evaluated on FTO-coated glass plates. The device performance has been tested in three different electrolytes, namely, 6 M KOH, 1 M H₂SO₄, and 0.5 M solution of 1-Butyl-3-methylimidazolium hexafluorophosphate in acetonitrile. The supercapacitor with ANC electrode in 6 M KOH electrolyte yielded a specific capacitance of 97.77 F g⁻¹ at 1 A g⁻¹ current density and retained 93% efficiency after 5000 cycles, quite comparable to the commercial carbon-based device. The device also showed a higher energy density of 11 Wh kg⁻¹ and power density of 900 W kg⁻¹. While using the ionic liquid electrolyte, the specific capacitance was lowered to 40.44 F g⁻¹ at 1 A g⁻¹ current density, but with a wider potential window of 2.5 V.

There is a growing interest in the study and exploitation of graphene, expressed in numerous recent studies, both theoretical and practical. Here, graphenes were theoretically investigated using molecular descriptors. The complete set of 22 graphene conformers, with five cycles of six connected carbon atoms, was subjected to the study. The Zagreb index family was used in the first instance. The analysis showed that, in the case of the analyzed graphenes, the degeneracy of the Zagreb indices is very high. In addition, when the first Zagreb index is degenerate, the structures can still be discriminated by the second Zagreb index. However, when the second Zagreb index is also degenerate, the entire Zagreb index family built with expressions involving vertex degree on adjacent ones is degenerate. Thus, its use in the case of graphenes is not recommended. In general, topological descriptors have a low power of discrimination in classes of conformers. Moreover, for a pair of conformers, even the extended Hückel energy is degenerate. In this case, the resolution can be obtained with descriptors generated from molecular geometry. Furthermore, using a pool of descriptors exploring the robustness of topology and resolution of geometry significantly increases the accuracy of structure to property prediction. The SMPI (Szeged matrix property indices) family of descriptors has been used here as an alternative, and discriminated all 22 conformers adequately. A simple linear regression, explaining over 99.97% of the extended Hückel energy using one SMPI descriptor, has been found, showing thus the potential of the SMPI family in graphene discrimination in particular and materials science-related structure-based estimations and predictions in general.</p>\u0000 </div>","PeriodicalId":11765,"journal":{"name":"Energy Storage","volume":"7 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144869159","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}

This paper offers an optimal charge scheduling approach for EVs at solar-powered charging stations (CSs) that rely on solar power generation. The primary objective of the proposed algorithm is to schedule EV charging based on the availability of solar PV energy in order to reduce total charging costs. This paper uses an enhanced red panda optimization (ERPO) algorithm to effectively schedule charging and discharging in EV battery management, thereby improving the operation of solar-powered EV charging stations (EVCSs). The optimal operation is achieved by regulating the power flow among the PV system, energy storage unit, EVCS, and the grid.
