As a complex dynamic system, the charging and discharging process of LiBs involves the evolution of multiphysics fields, such as concentration, electricity, and stress. For quantitative analysis of the internal mechanisms of LiBs, as well as the development guidance and performance prediction of high-performance batteries, modeling has advantages that cannot be matched by traditional experimental methods. Major research efforts in the past decades have made significant strides in modeling the internal processes and physical field evolution of LiBs. Importantly, the scattered ideas need to be integrated into a structured framework to form a complete LiBs multi-physical field model. This work reviews important advances in LiBs modeling from the perspectives of describing the internal processes of the battery and portraying the evolution of the physical field. First, quantitative descriptions of the charging and discharging behaviors and the side reactions are reviewed to investigate the battery reaction mechanisms. In addition, the characterization of the evolution of the stress and temperature fields within the battery as well as the coupling between them and the internal reactions are discussed. Finally, some suggestions for future improvements in the modeling are given, ranging from equation optimization to parameter acquisition and the application of artificial intelligence. It is hoped that this work will facilitate the development of models with sufficient accuracy and efficient computational cost to provide guidance for the improvement of LiBs.</div></div>","PeriodicalId":100356,"journal":{"name":"DeCarbon","volume":"6 ","pages":"Article 100076"},"PeriodicalIF":0.0,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142531528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multi-component synergism and complex microstructure design are effective measures to improve the EWA and EWS properties. However, how to implement the above designs still faces huge challenges. Herein, multi-interface carbon-coated FeCoNi nanoneedles grown on carbon cloth (FeCoNi@C/CC) were synthesized by a combination of hydrothermal process and chemical vapor deposition (CVD) technology with the concept of “green synthesis”. Using acetylene as the carbon source and atmosphere, the FeCoNi ternary hydroxide can be transformed into a multiple magnetic component (Fe<sub>3</sub>O<sub>4</sub>, Ni, and Co metals) by simple annealing. Simultaneously, a uniform carbon layer is formed on the surface, resulting in a composite system with a variety of heterogeneous interfaces and loss mechanisms. Additionally, the dielectric and magnetic loss capacities can be effectively adjusted by changing the temperature of CVD. The optimized FeCoNi@C/CC as filler exhibits remarkable EWA performance with a minimum reflection loss of −69.3 dB at a thickness of 1.82 mm and a maximum effective absorption bandwidth of 6.80 GHz. Moreover, the composites as an integrated component also show a fascinating electromagnetic interference shielding efficiency of 42.2 dB.
