Activated sludge treatment requires significant energy input for aeration and produces unpleasant odors. MFCs eliminate the need for energy-intensive aeration, simultaneously generating energy during wastewater treatment. Platinum-based electrodes commonly used in the cathode of MFCs pose a significant cost barrier, necessitating advancements in electrode materials for practical, large-scale application. This study reports on the performance of a continuous methanogen biocathode MFC system engineered to simultaneously treat cattle-barn wastewater and utilize carbon dioxide without 2-bromoethanesulfonic acid (BES). Carbon felt treated with nitric acid without BES successfully reduces methane production by 93%. An MFC configuration utilizing nitric acid-treated carbon felt as the anode and an oak-derived carbon electrode as the cathode effectively treat wastewater and convert CO2 to methane, yielding a power density of 5.5 mW m−2 and Coulombic efficiency of 7.3%, approximately twice those without nitric acid treatment and surpassing even the performance of the system with BES treatment. This system represents a promising, low-cost, and environmentally sustainable approach to renewable energy production and livestock wastewater treatment.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 4","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ente.202401558","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793872","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}

Hybrid supercapacitors (SCs) gain promising interest due to their exceptional electrochemical performance similar to batteries (high-energy density) and SCs (high-power density). The excellent performance of the electrode material is significantly influenced by the employed synthesis route. The copper phosphate (Cu3(PO4)2) nanomaterials are synthesized using hydrothermal and sonochemical techniques. Two- and three-electrode configurations are utilized to evaluate the electrochemical performance of the as-prepared nanomaterials. An incredible specific capacity of 443.86 C g−1 at 1.4 A g−1 is achieved through sonochemically obtained nanomaterial (S2). In two-electrode configuration, S2 is used as a positive electrode material to fabricate an asymmetric device, which provides an energy density of 51.2 Wh kg−1 and power density of 6800 W kg−1 at 0.9 and 8.0 A g−1, respectively. The device also demonstrates an exceptional capacity retention of 93.45% after 1000 galvanostatic charge–discharge cycles at 5 A g−1.

However, traditional methods for preparing activated carbon from chitin often require substantial amounts of activators and complex carbonization processes, leading to suboptimal energy storage efficiency. This study presents a partial dissolution system achieved by modulating the mass ratio of chitin to activators (KOH and urea) and optimizing freeze-thaw cycles. When chitin/KOH/urea is mixed at a 1:1:1.5 mass ratio and subjected to three freeze-thaw cycles, the resulting porous carbon demonstrates a high specific surface area of 1783 m2 g−1 with significant N (4.75%) and O (11.16%) doping. The electrode achieves a specific capacitance of 309.1 F g−1 at 0.5 A g−1 in a three-electrode system with 6 m KOH as the electrolyte. After 5000 charge–discharge cycles at 5 A g−1, the capacitance retention rate remains at 91.08%, indicating excellent cycling stability. When assembled into a symmetrical supercapacitor, it exhibits an energy density of 5.69 Wh kg−1 at a power density of 4996.1 W kg−1, demonstrating remarkable energy storage performance.

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}

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.

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.

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.

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}
