Herein, an experimental exploration is carried out to unveil the thermal runaway properties of power cells at tunnel scenarios, whereby the impact of heating patterns (electric oven and plate) and heating powers is involved as well. Under the effect of various heating patterns, cells show quite different thermal runaway properties inside a tunnel. In the oven case, the cell is uniformly heated, leading to two instances of smoke/gas release, followed by ejection fire and stable combustion. Whereas, the cell under the plate pattern illustrates smoke/gas releasing only once, with no combustion occurring due to the relatively low surrounding temperature. In addition, the cell affected by a plate experiences a process of thermal runaway propagation, i.e., the left part of the cell encounters thermal runaway first and then propagates to the right part, with the severity of the thermal runaway increasing over time. The cell heated by an oven illustrates worse thermal hazards with a more dramatic temperature rise and heat release, though the associated smoke hazard is relatively mild. The thermal conductivity of the cells is calculated to be approximately 3800 W/(m·K). The power of electric ovens and plates shows little impact on the heat release, mass loss, and smoke release of cells during thermal runaway. Finally, the dimensionless temperature rise at specific positions along the tunnel ceiling exhibits an exponential reduction as the dimensionless position increases during thermal runaway.</div></div>","PeriodicalId":15942,"journal":{"name":"Journal of energy storage","volume":"106 ","pages":"Article 114814"},"PeriodicalIF":8.9,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142746323","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}

The effect of polymer content, aggregates ratio (fine sand to medium sand) and filler types (bentonite, clay, and fly ash) on gas permeability, tensile strength, and resistance to high and low temperature of PPM were conducted. The scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) were performed to characterize the microstructure of PPM. Additionally, numerical simulations were performed to analyze the stress distribution characteristics of PPM when used as a sealing structure. The results demonstrate that PPM exhibits low gas permeability (10⁻²¹ m²), high tensile strength (up to 2.96 MPa), and significant tensile strain (up to 27.02 %), with a relatively low elastic modulus (11.87–35.05 MPa). Meanwhile, PPM containing fly ash showed the highest strength, followed by those with clay, while PPM with bentonite exhibited the lowest strength. However, only the PPM with bentonite as a filler remained stable and did not collapse under high temperatures. The hoop stresses in the PPM are only compressive and not tensile, and the maximum hoop tensile strain remains well below the ultimate tensile strain of the material, thus preventing the tensile damage and ensuring the gas-tightness. These findings provide a theoretical basis for using PPM in CAES sealing applications, and advance the understanding and application of sealing materials in CAES man-made caverns.</div></div>","PeriodicalId":15942,"journal":{"name":"Journal of energy storage","volume":"106 ","pages":"Article 114845"},"PeriodicalIF":8.9,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142757736","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}

It provides a theoretical specific capacity of over 300mAh/g for LLOs, but it is also the main source of issues such as low Initial Coulombic efficiency (ICE), poor rate performance, and voltage decay. In recent years, related research has primarily focused on the lattice oxygen. From the perspective related to the Li₂MnO₃ phase, this study achieves different activation degrees of Li₂MnO₃ phase through ingenious electrochemical methods. It conducts a detailed analysis of the phase transition and polarization of Li₂MnO₃ phase under high and low rates, and delves into the different mechanisms that cause the electrochemical performance degradation of LLOs under high and low rates. The results show that during low-rate cycling, the more Li₂MnO₃ phase in LLOs, the more transformation of crystal structure from layered to spinel phase occurs during cycling, and the structural transformation of the material will ultimately lead to the degradation of cycle performance and voltage decay. During high-rate cycling, due to the intrinsic conductivity difference of Li₂MnO₃ phase, the large polarization effect of LLOs can lead to severe decomposition of the electrolyte at high voltages, resulting in the degradation of cycle performance. Therefore, conducting research on LLOs focused on the Li₂MnO₃ phase may be an effective approach, providing a new modification idea for achieving more excellent cycling performance of LLOs.</div></div>","PeriodicalId":15942,"journal":{"name":"Journal of energy storage","volume":"106 ","pages":"Article 114808"},"PeriodicalIF":8.9,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142757741","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}

Each link has its features, and they are interlinked. Industry chain development cannot be separated from the mutual promotion of all links in the industry chain. The scientific and technological innovation of the lithium-ion battery chain is widely studied because it is considered one of the most promising energy storage systems. Moreover, scientific development is widely considered to promote technological innovation, and the contribution of knowledge from science to technology is studied by analyzing citations from patents to papers. However, there are two research gaps. First, there is little research on the contributions of science and technology in the lithium-ion battery field. The second gap is the lack of an industrial chain view in the study of science–technology linkages. Therefore, this study proposed a framework to reveal the knowledge contributions from science to technology from the industry chain view and applied it to the lithium-ion battery industry. The findings are summarized as follows: (1) A total of 130 topics were mined, summarized, and classified from the industry view. The electrode, battery management and electrolyte are relatively complex and are more discussed, especially regarding the electrode. (2) Knowledge contributions from science to technology have concentrated on the electrolyte, electrode and battery management. The knowledge contributions from paper topics on the electrode to patent topics on the electrode are the strongest. Patent inventors who focus on these three elements should refer to science on this element and science on the other two elements. Besides, policy- makers could promulgate promotion policies to stimulate the scientific development of these three elements, especially for the electrode. (3) Garnet-type ceramic sintering was the topic that had the greatest contributions in 2017 and 2018, and the patent topic to which it contributed as the most was “garnet-type ceramic sintering. Silicon has a consistently high degree of knowledge interaction between science and technology. These findings could serve as a reference for policy-makers when making incentive policies and scholars when selecting research content.</div></div>","PeriodicalId":15942,"journal":{"name":"Journal of energy storage","volume":"106 ","pages":"Article 114694"},"PeriodicalIF":8.9,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142746405","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}
