MFCs are bioelectrochemical systems that use exoelectrogenic bacterial communities under anaerobic conditions to convert chemical energy into electrical energy. These systems are attracting attention due to their potential to reduce overall energy consumption, produce zero carbon emissions, and exhibit high energy density. The rapid development of renewable energy sources has increased the potential for bioenergy, particularly MFCs, to become one of the most important energy sources of the future. In addition to energy production, MFCs show potential for bioremediation and efficient removal of various pollutants. While MFC technology currently has limited application at the laboratory level, it is expected to increase in commercial use in the near future and offers great potential in the areas of renewable energy and environmental sustainability. This review article focuses on the historical and ecological development of the components used in MFCs, examining in detail their evolution and use in MFCs for renewable energy production.","PeriodicalId":15579,"journal":{"name":"Journal of Electrochemical Energy Conversion and Storage","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2023-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44445240","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}

In this structure, batteries are divided into two forms: intra-group and inter-group; the intra-group equalization is the lower-level equalization while the flying capacitor circuit is used as an equalization circuit to achieve equalization between individual battery cells; the inter-group equalization is the upper-level equalization while Cuk circuit is used as equalization circuit to achieve equalization between battery packs; each battery pack shares a battery cell, thus to obtain more options on equalization path. The proposed strategy, with State of Charge as the balancing variable, represents topological structure of the circuit in form of graph by adopting graph theory control, seeks the optimal equalization path via ant colony optimization algorithm with global search, thus to improve the equalization speed and efficiency. At last, the structure and the strategy proposed in this paper were simulated in MATLAB/Simulink to compare with the maximum value equalization method in the condition of static, charging, and discharging. The result of the simulation experiments shows that the equalization method based on graph theory control reduces the equalization duration by approximately 17%, and improves the equalization efficiency by approximately 2%, which verifies the superiority and effectiveness of the structure and strategy proposed in this paper.","PeriodicalId":15579,"journal":{"name":"Journal of Electrochemical Energy Conversion and Storage","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2023-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48922414","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}

LiF, Li2O, and Li2CO3 are important inorganic components of SEI. This electrode-electrolyte surface forms during the battery's first charging/ discharging cycle, preventing electrons' movement through the electrolyte and stabilizing the Lithium-ion battery. However, the concern is inorganic SEI components cause rate limitation of Lithium-ion diffusivity through the SEI layer. Lithium-ion diffusivity through the SEI layer depends on many factors such as temperature, the width of the SEI layer, and the concentration/density of the layer. Lithium-ion diffusivity dependence on temperature, at working temperatures of lithium-ion batteries was observed at temperatures from 250 K to 400 K and diffusion coefficient data at higher temperatures also been observed. Lithium-ion diffusivity at varying concentration/density was also observed in this paper using the Reactive force field (ReaxFF) molecular dynamic simulation. To improve the Lithium-ion diffusivity, vacancy defects were created in the inorganic components of SEI layer LiF, Li2O, and Li2CO3 and observed the diffusion coefficient using the ReaxFF molecular dynamic simulations.

However, a retired battery pack is not suitable for direct reuse due to the poor consistency of in-pack batteries. This paper proposes a method of retired lithium-ion battery screening based on support vector machine(SVM) with a multi-class kernel function. First, 10 new NCR18650B batteries were used to carry out the aging experiments for collecting the main parameters, such as capacity, voltage and direct current resistance(DCR). Second, a SVM based on a multi-class kernel function was proposed to screen retired batteries. To improve the screening efficiency, a capacity/voltage second-order conductance curve was adopted to extract their capacity features quickly, and four new feature points were selected as the input of the SVM to classify retired batteries. Finally, the retired batteries are accurately divided into four classes by the trained model, and the classification accuracy can reach 97%. Compared with the traditional method, the feature extraction time can be reduced by four-fifths, and the screening efficiency is greatly improved.","PeriodicalId":15579,"journal":{"name":"Journal of Electrochemical Energy Conversion and Storage","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2023-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42606877","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}

This paper attempts to estimate the short-circuit resistance of the cell using the mean difference model and relies on the estimated results to make a quantitative analysis of short-circuit fault. To achieve this goal, a combination of forgetting factor recursive least squares and extended kalman filter is used to estimate the average open-circuit voltage within the battery pack. Subsequently, since both the open-circuit voltage (OCV) and intrinsic mode function (IMF0) components reflect the low-frequency characteristics of battery voltage, we propose a new method based on the variational modal decomposition to extract the differential open-circuit voltage of the battery, and finally make an estimate of the short-circuit resistance after obtaining OCV of the battery using the idea of the mean difference model (MDM). In addition, the effectiveness of the proposed method is verified under different degrees of short-circuit faults by connecting different resistors to the series battery pack.","PeriodicalId":15579,"journal":{"name":"Journal of Electrochemical Energy Conversion and Storage","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2023-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42229114","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}

The four candidate SOFC plants included a standalone SOFC plant, a standalone SOFC plant with a steam bottoming cycle, an SOFC/ (gas turbine) GT hybrid plant, and an SOFC/GT hybrid plant with a steam bottoming cycle. To capture dynamic behaviors caused by long-term SOFC degradation, this study employed a pseudo-stead-state approach that integrated real-time dynamic 1D SOFC models (degradation calculation embedded) with steady-state balance-of-plant models. Model simulations and eco-techno-economic analyses were performed over a 30-year plant lifetime using matlab simulink R2017a, aspen plus V12.1, and python 3.7.4. The results revealed that, while the standalone SOFC plant with a steam bottoming cycle provided the highest overall plant efficiency (65.0% LHV), it also had high SOFC replacement costs due to fast degradation. Instead, the SOFC/GT hybrid plant with a steam bottoming cycle was determined to be the best option, as it had the lowest levelized cost of electricity ($US 35.1/MWh) and the lowest cost of CO2 avoided (−$US100/ton CO2e).","PeriodicalId":15579,"journal":{"name":"Journal of Electrochemical Energy Conversion and Storage","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2023-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46323836","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}

In particular, when the heat gets the least possibility to escape from the electrode surface, the boundary of the packaging material remains the sole heat dissipator. In this regard, the heat gets accumulated in the central zone, making it the most critical, since it has the least possibility to escape to the surroundings. Anticipating such a heat trap, a central heat sink component is devised, where the role of its conductivity and the relative scale is analyzed based on the formation of transient and steady-state temperature profiles. Additionally, an analytical solution is attained for the location of the maximum temperature, where its value and correlation with the electrolyte conductivity, heat generation rate, and scale of the cell have been quantified. Due to the existence of the curved boundaries, it is shown that the time versus space resolution for capturing the transient evolution of the temperature is more strict than the flat surface and analytically acquired as ≈33% smaller value. Such enhanced design and subsequent analysis are critical for planning sustainable and cost-effective packaging to avoid the ignition and failure of the respective electrolyte.","PeriodicalId":15579,"journal":{"name":"Journal of Electrochemical Energy Conversion and Storage","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48570476","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 hydrothermal method is used to synthesize the sulfide-based materials. The structural morphology, elemental composition, and electrochemical properties are measured using X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy, and potentiostat system. The specific capacitance is enhanced up to 1964.2 F/g by making the composite with carbon nanotubes (CNTs), which is higher than the reference sample (MnS). In the case of a real device, the obtained value of specific capacity in manganese sulfide/CNTs/activated carbon is 240 C/g which is much improved compared to the previously reported values. In a supercapattery device, an excellent energy density of 53.3 Wh/Kg and a high power density of 7995 W/kg are obtained. The stability of the device is measured up to 1000 cycles and achieved the specific capacity retention of 86% with columbic efficiency of 97%.
