All modes of heat transfer including conduction, forced and natural convection, radiation from the exhaust system, battery cooling, and battery internal heat generation are considered in the model. The full-vehicle model is simulated under various vehicle conditions to represent four standard customer drive cycles. The simulated battery surface temperature at specified points along the battery module surfaces is compared to experimental vehicle test-cell data to provide model validation. Using the results from the transient thermal simulations, prediction of the battery thermal degradation is performed throughout the entire vehicle lifecycle. The thermal degradation is estimated using thermal goals and equivalent exposure times.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 4","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ente.202401331","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793750","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 practical application of low-cost commercial CNTs is limited by their moderate specific capacitance due to the relatively low surface area which is around 220 m2 g−1. This limitation can be addressed by applying proper compressive stress to the CNTs, resulting in improved capacitance. The effects of compression on capacitance vary depending on the length and inner diameter of the CNTs, which have been systematically investigated. It has been found that longer and narrower CNTs exhibit more significant improvements in capacitance due to compression. Specifically, under 12 MPa, there is an ≈135% increase in specific capacitance compared to that under 1 MPa, with the optimum value of 68.2 F g−1 at 1 A g−1. An excellent rate capability of 93.5% at 40 A g−1 is also obtained by compression. Furthermore, when an light emitting diode light is powered by a compressed CNT-based SC, both brightness and lasting time are dramatically enhanced compared to the case without compression. This cost-efficient strategy for improving the energy storage performance of CNTs may facilitate their practical application as electrode materials for ultrafast supercapacitors.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 4","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793544","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, during lithium insertion and deinsertion, Si undergoes significant volume expansion, leading to rapid capacity degradation, which has limited its application as an anode material in LIBs. To address this issue, coupling Si with carbon enables the combination of the high lithiation capacity of Si with the excellent mechanical strength and electrical conductivity of carbon. This synergy makes silicon/carbon composites (Si/C) ideal candidates for LIB anodes. In this review, recent advancements in Si/C composite materials for LIBs are categorized based on synthesis methods and design principles.

Additionally, the required experimental process design is time and material-intensive, increasing the development costs of new materials or cell designs. A model of the filling process would allow for more efficient cell production, but until now, the published models have mainly been focused on individual components on a pore scale. Within the scope of this work, the model setup for a holistic examination of the electrolyte filling process is shown, allowing the study of the electrolyte wetting on a cell scale. The characteristic values of a porous medium, such as the permeability, are calculated with a microsimulation of an anode and a cathode pore structure. These values are then transferred to the ANSYS porous media model, and cell scale simulations are performed. Two cell formats and variations in the evacuation pressure and electrolyte temperature are simulated and compared to experimental wetting data. The results show that the simulation successfully models the wetting behavior for the investigated cell formats and cell assembly types, validating the model with experimental data both qualitatively and quantitatively.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 4","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ente.202401708","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793633","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}

In this study, amino-modified porous aromatic frameworks (AMPAF) are prepared. The amino group in AMPAF stabilizes the anion through hydrogen bonding to reduce the dissociation energy barrier of Li+, enabling Li+ to be more easily dissociated from lithium salts. Additionally, the abundant pores of AMPAF promote the rapid transport of Li+. The prepared quasi-solid polymer electrolyte (AMPAF-QSPE) exhibited a high Li+ conductivity of 7.62 × 10−5 S cm−1 and a Li+ transference number as high as 0.55, which proves the restriction of the amino group in AMPAF on the movement of anions and the ability to dissociate lithium salts. The discharge specific capacity of Li//AMPAF-QSPE//LiFePO4 reached as high as 137 mAh g−1 at 0.2 °C, and the capacity retention rate was stable at 85% after 200 cycles. This article presents an effective attempt to enhance the overall performance of polymer electrolytes using amino-modified PAF, offering an innovative perspective for the development of electrochemical energy storage technologies.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 4","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793543","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}

A heliostat's main function is to redirect sunlight for use in a variety of applications, including heating, lighting, scientific research, and solar power generation. The two-axis tracking employed in the device ensures that the reflected irradiance is aimed at a predetermined target. The design and evaluation of a tilt-roll two-axis tracking heliostat are presented in this article. The model consists of a mirror 0.45 m in width and 0.45 m in length installed on a pedestal of height 0.75 m. The motion of the heliostat is controlled using two separate linear drives via a sun-tracking algorithm implemented in a microcontroller. A small-scale tilt-roll design with a reflective area (mirror) of 0.2025 m2 is established. This novel design eliminates the need for commercially available solar tracking systems and can be deployed in areas of limited installation space. Dual-axis heliostat design used here provides an effective way to track the sun's movement for maximum solar energy capture by combining tilt and roll mechanisms. This design ensures tracking precision for optimal solar energy concentration making it well-suited for experimental and smaller-scale deployments.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 3","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143565106","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}

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.

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}
