However, problems like gelling and emulsifying qualities make it difficult to use pea protein. To successfully overcome significant obstacles related to the use of pea protein in many industrial sectors, particularly meat, this study offers a combination of methods used to produce commercially accessible Pea Protein Isolate (PPI). High-intensity ultrasound (HIUS) at three magnitudes (2, 4, and 8 W/mL), heat at 60 °C, and pH at 10.0 were all integrated within the set.

However, practical applications are hindered by challenges such as dendritic lithium growth and the accumulation of dead lithium, which severely impact performance and safety. To address these issues, ultrasound has been proposed as a physical method to mitigate dendrite formation. In this study, we investigate the effects of real-time ultrasound application on LMBs and their subsequent electrochemical performance. Interestingly, our findings reveal that contrary to the intended effect, ultrasound accelerates the accumulation of dead lithium, worsening with continued cycling. Mechanical simulations indicate that the stress induced by ultrasound causes fragmentation and further dead lithium accumulation. This accumulation not only hinders reaction kinetics but also disrupts plating/stripping processes, leading to significant capacity retention issues. Consequently, ultrasound-treated cells exhibit higher over potential, lower coulombic efficiency, and faster capacity fade compared to untreated cells across half-cells, symmetric cells, and full cells. These results underscore that ultrasound negatively impacts the lifespan of LMBs, highlighting its critical adverse effects on the porous, dendritic structure of LMBs. Therefore, this provides a novel insight that these dynamics are crucial for optimizing the application of ultrasound in future LMBs technologies.</div></div>","PeriodicalId":442,"journal":{"name":"Ultrasonics Sonochemistry","volume":"117 ","pages":"Article 107334"},"PeriodicalIF":8.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143768502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
