To enhance their electrochemical performance, La_0.5Pr_0.5Fe_0.7Mn_0.3O₃ (LAFE) redox powder was added on their electrodes. This powder had an orthorhombic structure and was formed by porous grains with sizes of 40–120 nm according to the microscopy and X-ray diffraction analyses. Donut-like SCs (contained acidic electrolyte) made with and without LAFE had capacitances of 182.8 and 334.7 F g⁻¹, respectively. Although the device made with LAFE had lower capacitance, it presented a battery component (prolonged discharge at a stable voltage of 1.2 V), which produced a high capacity of 1555 mAh g⁻¹. In contrast, the donut-like SC made without LAFE had a lower capacity of 260 mAh g⁻¹. Other donut-like SCs were made with an amber electrolyte derived from recycled lithium-ion battery (LIB) electrodes (collected from expired LIBs). Those devices had lower capacitances and energy-densities of 96–230 F g⁻¹ and 36–42 Wh kg⁻¹, respectively. For comparison purposes, rectangular SCs were fabricated with and without LAFE redox powder and obtained capacitances/energy-densities of 970.8 F g⁻¹/194.2 Wh kg⁻¹ and 562.5 F g⁻¹/112.5 Wh kg⁻¹, respectively. Thus, adding the LAFE powder to the rectangular SCs incremented their capacitance by ⁓73 %. Those rectangular devices were also immersed in water at room temperature or under cold water (5 °C); consequently, the capacitance decreased by 45–53 %. The analysis by Raman spectroscopy, optical-absorption, and XPS spectroscopy demonstrated the existence of Fe³⁺/Fe²⁺ and Mn⁴⁺/Mn³⁺ species as well as oxygen-vacancy defects on the SC electrodes made with LAFE. Those ones promoted the storage of charge by redox-reactions. Hence, the results of this work revealed that donut-like energy sources can be fabricated from recycled six-pack rings, which avoids the contamination of the environment by microplastics. We also demonstrated that electrolytes can be produced from recycled LIB electrodes and could be used to fabricate efficient SCs. Both, the novel electrolyte and donut-like devices pave the way for the design of low-cost energy sources that can be used in wearable electronics.</div></div>","PeriodicalId":15942,"journal":{"name":"Journal of energy storage","volume":"106 ","pages":"Article 114628"},"PeriodicalIF":8.9,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142746472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, we first build a backbone network that combines a Long Short-Term Memory (LSTM) module and a Fully Connected (FC) module to perform fine-grained model training on the source domain. Then, the well-trained LSTM module is frozen and transferred to the target domain, and the FC module is fine-tuned using 30% of its early-cycle data.

The presence of ‘slits’ can reduce the utilization rate of the electrolyte and decrease mass transfer efficiency during the battery cycling process. However, the flow channel design for kilowatt (kW)-scale stacks often overlooks the impact of these slits. Therefore, this paper examines the influence of ‘slit’ structures on the flow characteristics of electrolytes within carbon cloth using kW-scale stacks with interdigitated flow channel structures as an example, and optimizes the interdigitated flow field with slits. The study analyzes the flow characteristics of electrolytes on carbon cloth in flow field structures with no slits, slits at both ends and slits on three sides. It further investigates the effects of slit width and the length of interdigitated flow channels on the flow patterns of electrolytes on carbon cloth when slits are present. Through numerical simulation, velocity and pressure distribution maps at the center of the carbon cloth, as well as velocity distributions at various positions, are obtained. The results show that slits affect the position and extent of the low-speed zone on the carbon cloth. As slit width increases, the resistance of the slit decreases, gradually increasing the flow velocity of the electrolyte towards the carbon cloth. However, when the slit width exceeds 0.5 mm, the impact of the slit on flow over the carbon cloth remains largely unchanged. With a fixed slit width of 0.5 mm, increasing the length of the interdigitated flow channels reduces the flow velocity and pressure within the carbon cloth but significantly improves the uniformity of the carbon cloth. Extending the interdigitated flow channel length by 15 mm demonstrates the best overall effect.</div></div>","PeriodicalId":15942,"journal":{"name":"Journal of energy storage","volume":"106 ","pages":"Article 114703"},"PeriodicalIF":8.9,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142746477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
