These short circuits can result in explosive, thermally unstable states (so called thermal runaways).

This paper presents and compares experimental results of the mechanical characterization of individual cell components as well as whole pouch-cells under different loading patterns. Especially, the different mechanical behavior of the active materials NMC and graphite was investigated in dry and wet conditions. In compression tests, the presence of the electrolyte reduced the stress levels by about 100 % for the graphite layered anode (Cu) and by about 20 % for the NMC layered cathode (Al) compared to dry conditions. The separator displayed an anisotropy with tensile strengths differing by a factor of three between the longitudinal and transversal orientations. For investigating the failure of a whole pouch-cell, interrupted flat-punch and hemispherical-punch indentation tests were performed. Post-mortem CT analysis revealed that crack development is rather gradual than abrupt. The initiation and propagation of the failing cell structure were examined and related to the characteristics of the individual cell components.

Cyclic voltammetry results initially were used to recognize the procedures with the most improved kinetics. This demonstrated the influences of treatment procedures on electrode kinetics by showing an improved electrode rate constant. In the following, area-specific resistance obtained by the polarization curves technique was used to examine the role of the thermal treatment procedure on improvement of the mass-transfer effect and, consequently, explore a treatment procedure to maximize the electrode activity. Both obtained CV and ASR data showed a better performance for thermally treated SGL 4.65 EA compared to that of AvCarb G150. Enhancing the electrode kinetics due to thermal treatment showed the largest contribution to reducing the ASR indicated by electrochemical impedance spectroscopy of the SGL 4.65 EA.

In this work, a means by which to fabricate metal-supported SOFCs under an air environment is developed with a thin-film electrolyte, with deposition at room temperature. By introducing a pore-reducing layer while also controlling the viscosity of the coating solution, the surface of the anode is designed to be dense and flat, enabling the stable deposition of a dense thin-film electrolyte.

For real-life implementation, it is desirable for voltage reconstruction to work for partial charging as real-life batteries are rarely charged fully. In this pursuit, the presented work investigates a common practice of using truncated data from full charge as a representation of partial charging in voltage reconstruction. Usage of truncated data is prevalent despite known deviations between data collected from partial and full charge cycles and has resulted in a misconception that accurate voltage reconstruction is achievable using partial charging data. Therefore, voltage reconstruction errors between models parametrised using truncated data and actual partial charging data were compared. Results show a four-fold increase in error when using truncated data, which indicates that truncated data is an inappropriate proxy of partial charge. The findings also imply that partial charging is a limitation of voltage reconstruction modelling not highlighted before due to usage of truncated data. This limitation must be addressed to improve the applicability of voltage reconstruction. The study also emphasises the need to generate new battery degradation datasets with appropriate inclusion of partial charging data to enable the development of accurate and holistic models.</div></div>","PeriodicalId":34318,"journal":{"name":"Journal of Power Sources Advances","volume":"33 ","pages":"Article 100175"},"PeriodicalIF":5.4,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143760824","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}
