Based on the different forms of energy losses, the prevalent energy harvesting technologies in the NEV domain are elucidated, with a focus on the fundamental principles of vibration energy, braking energy, wind energy harvesting, and their recent advancements in practical implementations. Vibration energy harvesting involves the conversion of mechanical energy from the suspension system into electrical energy, while brake energy harvesting captures a portion of the brake friction loss as electrical energy during braking, and wind energy harvesting utilizes wind power generators on the vehicle surface to produce electricity. By quantitatively evaluating the recovery effects of different types of systems, the report demonstrates the great potential of energy harvesting technologies to improve energy efficiency and extend the range of NEVs. Furthermore, it explores the future trajectory of energy harvesting technology, envisioning its integration as a standard feature in NEVs and heralding transformative progress in the global energy and transportation sectors.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 4","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, research so far has exclusively focused on isolated understanding of individual aspects such as the performance, safety, or cost. This study introduces a global optimization framework for battery systems with tabless cylindrical cells based on the groundwork laid within recent years. The framework is applied to gain comprehensive understanding of cross interactions between different design variables and the key performance indicators of the battery system. It was found that a well-defined diameter exists which optimizes the battery energy for given boundary conditions. The multiobjective trade-off between energy, performance, weight, and cost however might lead to different solutions with respect to the desired properties of the system. Small cylindrical cells with diameter less than 25 mm provide enhanced performance but lower energy and higher cost. Very large cylindrical cells with diameter more than 50 mm have less options for interconnection but provide the best cost-saving potential. With realistic constraints, only diameters larger than 40 mm achieve Pareto-optimal solutions. Aluminum housings are found to outmatch steel housings in nearly all properties, especially for larger diameters. Considering the widespread introduction of aluminum housings is recommended for automotive manufacturers.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 4","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ente.202401479","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the weak conductivity of the sulfur and discharge products, the drastic breakdown and migration of the intermediates of lithium polysulfide (LiPSs) leading to shuttle effect, and the enormous volumetric change of sulfur particles upon cycle substantially hinder their practical uses. Due to the considerable capacity diminishing caused by the shuttle impact corrosion of the lithium metal, LSBs are thought to have significant commercial application challenges. Engineering nanomaterials’ surface structures can increase the affinity between the cathode with the LiPSs while also enabling the redox kinetics of the LiPSs, which results in a low level of LiPSs in the electrolyte that can restrict the shuttle effect. Sulfur and carbon materials, when combined, effectively increase the efficiency of active materials, increase the conductive properties of cathode components, and serve as a barrier against polysulfides. In this review, a thorough analysis is provided on low-dimensional carbon materials as cathode, by which the electrode modification technique for limiting the shuttle effect of polysulfide in LSBs and forecast future research trends on the same.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 4","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Structural analysis reveals the simple cubic crystal structure of double perovskite oxides. Phonon properties indicate the dynamical stability of Sr2GeCrO6, Ba2MgMoO6, and Ba2ZnMoO6 compounds. The band structure analysis indicates the metallic character of Sr2GeCrO6. However, generalized gradient approximation of Perdew–Burke–Ernzerhof and modified Becke–Johnson both suggest the indirect semiconducting nature of Ba2MgMoO6 and Ba2ZnMoO6. The crystal orbital Hamilton population (–COHP) examination evidences the strongest bonding interactions of O–Ba in these perovskite oxides. Both Ba2MgMoO6 and Ba2ZnMoO6 compounds exhibit p-type character, as indicated by the partial charge density distributions in the highest occupied molecular orbital and lowest unoccupied molecular orbital (LUMO) orbitals, which govern the band edges near Fermi level. LUMO orbitals are located on Mo and O atoms and are composed of heteronuclear s- and p-type interactions.

Nevertheless, choosing an hole transport layer (HTL) with optimal band alignment, superior carrier mobility, and low cost remains crucial for stable and efficient solar cells. In this regard, a series of inorganic metal sulfide HTLs such as FeS2, WS2, TiS2, HfS2, TaS2, and NiS2 is proposed to unveil its potential for novel SrZrSe3 absorber via SCAPS-1D by varying the key parameters of electron transport layer, absorber, and HTLs respectively. Interestingly, optimizing their properties boosts the built-in potential up to 1.06 V, resulting in effective separation and transportation of charge carriers toward their respective contacts. Furthermore, it increases absorption up to ≈6.5% by extending the absorption range toward the NIR region (700–850 nm) in all the solar cells. Finally, maximum power conversion efficiency of 21.77, 26.78, 27.60, 27.65, 27.63% with JSC of ≈29.3 mA cm−2 and less energy loss of ≈0.3 V for FeS2, WS2, TiS2, HfS2, TaS2, and NiS2 solar cells is accomplished.

FCHEVs are powered by a combination of FC systems, rechargeable batteries, ultracapacitors, and/or mechanical flywheels. FC technology appears to hold potential in terms of extended driving distances and quicker refueling times for vehicles that emit no exhaust fumes. A significant number of research studies have examined various types of energy-storage devices as vehicle power supply, their interfacing with the drive mechanism using power converters and their energy management strategies (EMS). In this article, various EMS for FC-based EVs are discussed. Classifications of FCEVs, BEVs, and EMSs for FCHEVs are developed by various researchers.
