Machine learning has been widely utilized to construct data-driven solutions for high-accuracy predictions. However, the internal mechanisms of batteries are sensitive to many factors, such as charging/discharging protocols, manufacturing/storage conditions, and usage patterns. These factors will induce state transitions, thereby decreasing the prediction accuracy of data-driven approaches. Transfer learning is a promising technique that overcomes this difficulty and achieves accurate predictions by jointly utilizing information from various sources. Hence, we develop two transfer learning methods, Bayesian Model Fusion and Weighted Orthogonal Matching Pursuit, to strategically combine prior knowledge with limited information from the target dataset to achieve superior prediction performance. From our results, our transfer learning methods reduce root-mean-squared error by 41% through adapting to the target domain. Furthermore, the transfer learning strategies identify the variations of impactful features across different sets of batteries and therefore disentangle the battery degradation mechanisms and the root cause of state transitions from the perspective of data mining. These findings suggest that the transfer learning strategies proposed in our work are capable of acquiring knowledge across multiple data sources for solving specialized issues.</div></div>","PeriodicalId":100489,"journal":{"name":"eScience","volume":null,"pages":null},"PeriodicalIF":42.9,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141132075","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}

Reducing the weight of Cu CC with minimum thickness and desirable mechanical strength is critical in enhancing energy density but is technically challenging. Herein, we demonstrate a fast and scalable chemical coating method based on electroless plating for fabricating ultralight CC (∼1.72 mg cm<sup>−2</sup>) with a thin Cu layer (500 nm) on an ultrathin polyethylene (PE) polymer scaffold (5 μm). The ultralight and ultrathin CC possesses high metal purity, high mechanical strength, high thermal stability, and outstanding electrochemical performances in lithium-ion and lithium-metal battery systems. Our ultralight CC only exhibits ∼30% of the weight of 6 μm Cu foil, leading to a 5−10% improvement in cell-level gravimetric energy density without sacrificing volumetric energy density.
