For the above problems, the lithium battery second-order RC equivalent circuit model is established, and then the model parameters are identified using the multi-innovation least square algorithm (MILS). Finally, Iterative unscented Kalman particle filtering algorithm with fused Rauch-Tung-Striebel Smoothing Structure (RTS-IUPF) applied to Li-ion battery SOC and SOH joint estimation is proposed. The algorithm is based on the identification of battery parameters, the controller reads the sensor data and predicts the state results. RTS smoothing structure can do posterior estimation, and a significant probability density function is generated to select the optimal particle, and unscented Kalman algorithm regularized particles. The algorithm reduces the effect of the process noise covariance matrix and the measured noise covariance matrix on the filter accuracy and response time in traditional unselected Kalman filters. The algorithm proposed in the paper improves particle degradation and increases the estimation accuracy. Finally, the RTS-IUPF algorithm performs simulation analysis in Pulse current discharge condition and dynamic current condition (NEDC) respectively. The pulse current experimental results show that the mean absolute value error of UKF and PF (Number of particles N is 300) are 1.26% and 1.24%, respectively, while the error of the RTS-IUPF is 0.748%. The RMSE of the RTS-IUPF is reduced by 66.5% and 77.8% compared with UKF and PF. Furthermore, The error of joint estimation using this algorithm is smaller than that of single estimation. The RMSE of the RTS-IUPF Joint is reduced by 27.4% compared with RTS-IUPF. The feasibility and effectiveness of the algorithm for the joint estimation of SOC and SOH of lithium batteries were verified.","PeriodicalId":15579,"journal":{"name":"Journal of Electrochemical Energy Conversion and Storage","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2022-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49649763","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 paper, the thermal runaway (TR) behaviors at different ambient pressures were studied. The thermal runaway onset time (t1) occured in advance as the ambient pressure decreased from 90 kPa to 50 kPa (90 kPa, 80 kPa, 70 kPa, 60 kPa, and 50 kPa). At 50 kPa, thermal runaway onset time of LIBs was 177 seconds earlier than that at 90 kPa. The values of heat release rate (HRR), total heat release (THR), battery peak surface temperature and peak flue gas temperature declined with the decreasing ambient pressure. Moreover, the peak concentrations of CxHy and CO increased with the decrease of ambient pressure, whereas the peak concentration of CO2 and NO showed the opposite trend. Based on the previous studies of the thermal analysis kinetics model of LIBs, a pressure correction factor kp was introduced to establish a prediction model for thermal runaway temperature at low pressure conditions. Based on the model output, the error of thermal runaway onset time t1 could be controlled within ±2 s, and the error of thermal runaway peak temperature Tmax could be controlled within ±2 °C. The experimental results were well consistent with the simulation results. The results of this study are beneficial to better reveal the thermal runaway behavior of LIBs under low ambient pressure.","PeriodicalId":15579,"journal":{"name":"Journal of Electrochemical Energy Conversion and Storage","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44281241","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, the failure mechanism remains unclear. This paper introduces the X-ray computed tomography to explore the gas production and copper dissolution of lithium battery during overdischarge state. From tomographic images in two different cross-section directions, the internal structure changes of bulge deformation and copper deposition are observed to quantitatively analyze the relationship between copper deposition and overdischarge state of charge. The position distribution is analyzed by density distribution feature, which indicate that the gas production is mainly distribute in the middle of the battery, and the copper deposition is distribute around the outer side. The experimental result shows that X-ray CT is a nondestructive, quantitative, visual and effective way to study the internal structure and material distribution of the over-discharge battery.

It is common practice to use Nafion membranes as PEMs, which have high ion exchange capacity. However, Nafion-based membranes also have high fuel permeability, decreasing fuel utilization and reducing the potential power density. This manuscript focuses on using graphene-coated (Gr-coated) PEMs to reduce fuel crossover. Protons can permeate across graphene and thus it can be employed in various devices as a proton conductive membrane. Here we report efficiency of Gr-coated Nafions. We tested performance and crossover at three different temperatures with four different fuel concentrations and compared to a Nafion PEM that underwent that same test conditions. We found that the adhesion of Gr on to PEMs is not sufficient for prolong fuel cell operation resulting in Gr delamination at high temperatures leading to a higher fuel crossover values compared to lower temperature testing. The results for 7.5M methanol fuel show a reduction of up to 25% in methanol crossover, translating to a peak power density that increases from 3.9 to 9.5 mW/cm2 when using a Gr-Coated PEM compared to a Nafion PEM at 30°C.","PeriodicalId":15579,"journal":{"name":"Journal of Electrochemical Energy Conversion and Storage","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2022-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46417232","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 work, the RED-MED coupled system was studied with a mathematical model, which was validated by our experimental results. The influences of RED channel length and the feed flow rate on the performance of the coupled system were studied. Furthermore, in the literature, only one of the two streams leaving RED, i.e. either the dilute or the concentrate, is split and partly mixed with another stream before being treated in MED. In this paper, a modified scheme is proposed, in which both the two streams were split, i.e. only a fraction of the concentrate solution was mixed with a fraction of the dilute. The purpose of the modification is to further reduce the total flow rate in MED. After the modification, both the energy efficiency and the heat exchange area requirement of MED increase. The optimum value of the split fraction was discussed. Results imply that while the studies reported in the literature mainly focus on the aspects closely related to the RED section, attention should also be paid to the overall scheme design of the RED-MED coupled system.","PeriodicalId":15579,"journal":{"name":"Journal of Electrochemical Energy Conversion and Storage","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2022-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45887117","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}

It is still widely used in electrochemical energy storage systems. In order to ensure the application of batteries under extreme working conditions, it is necessary to explore the degradation mechanism. In this study, the experimental battery is the same type of 2V-500Ah lead-acid battery produced by different manufacturers. Firstly, the three batteries were subjected to the same high temperature and high current cycle thermal shock test (50°C, 0.2C current), combined with quantitative analysis of plate active material and microscopic morphology observation. In addition, numerical studies are used to simulate the distribution of electrical parameters on the positive plate and grid. The above three parts are combined to study the causes of accelerated battery decay under high temperature and high current conditions. The results showed that the extreme conditions aggravated the non-uniformity of the potential distribution of the positive plate and the grid, which increased by 10.62% and 51.59%, respectively. The battery with higher remaining capacity has more a-PbO2 in the active material, and has a considerable amount of β-PbO2. The battery with the smallest remaining capacity has the largest volume of active material. The volume of the material affects the electrochemical reaction surface area. The larger the volume of the material, the higher the resistance of that part, which will lead to an increase in the overall impedance of the battery.","PeriodicalId":15579,"journal":{"name":"Journal of Electrochemical Energy Conversion and Storage","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2022-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46536396","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}
