The results showed that both the uniform corrosion rate and pitting rate followed the order: L360 > L245NS > antibacterial steel. Electrochemical tests further confirmed that the antibacterial steel demonstrated superior corrosion resistance, with the highest self-corrosion potential and a corrosion current density one-fifth that of L360 steel. Additionally, the antibacterial steel is more prone to passivation in the SRB environment. After 7 days of exposure, the sum of its charge transfer resistance and biofilm resistance was approximately 2.9 times that of L245NS steel and 3 times that of L360 steel. The addition of Cu to the antibacterial steel may contribute to inhibiting microbial growth and preventing biofilm formation, though this mechanism is controversial.</div></div>","PeriodicalId":13872,"journal":{"name":"International Journal of Electrochemical Science","volume":"20 4","pages":"Article 100960"},"PeriodicalIF":1.3,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143376833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this need, this paper proposes a method based on fine-tuning transfer learning and deep gate recurrent unit (DGRU) to estimate the SOH of different types of lithium-ion batteries. Firstly, the DGRU model is pre-trained by extracting highly relevant health indicators (HIs) from random known lithium-ion battery dataset to capture the dynamic characteristics of SOH over aging. Then, the fine-tuning pre-trained model is applied to the dataset of other batteries through transfer learning technology, enhancing the generalization capability of the proposed model on different battery types. Experimental results show that compared with baseline methods such as single-layer gate recurrent unit (SGRU), Gaussian process regression (GPR) and convolutional neural network (CNN), the proposed method has better comprehensive performance on different datasets. Specifically, the mean square error (MSE), mean absolute percentage error (MAPE), and the maximum error (MAXE) of the fine-tuning transfer learning-based deep gate recurrent unit (FTDGRU) model on B0006 cell are only 5.52e<sup>−4</sup>%, 0.22 %, and 0.0086, respectively, and the MSE, MAPE, and MAXE on CS2_36 cell are only 2.36e<sup>−4</sup>%,1.93 % and 0.0918, respectively.
