Summary: In this paper, a Deep Domain Adaptation Network (DDAN) is proposed for transfer learning among different batteries. The method incorporates domain adversarial mechanism and maximum mean discrepancy (MMD) to obtain domain invariant features between source and target datasets. Experimental results show that the proposed method reduces the error by over half compared to the direct prediction baseline, which is attributed to the intrinsic domain adaptation mechanism between source and target batteries. Our method outperforms existing methods and can be generalized to other batteries.

Summary: This article discusses a more difficult yet more practical source-free transfer setting, where there are only the models pretrained in source domain and limited target data can be available. To address the challenges of the absence of source data and distribution discrepancy in cross-domain SOC estimation, a novel source-free temperature transfer network (SFTTN) is proposed, which can mitigate domain shift adaptively. Experiment results indicate that SFTTN can achieve robust and accurate SOC estimation at different ambient temperatures under source-free scenario.

Summary: A study investigates the composition of the solid-electrolyte interphase (SEI) in lithium-ion batteries, revealing that the initially deposited components convert to monocarbonates and noncarbonate species regardless of salt concentration. The study also finds that the SEI becomes thinner with increasing salt concentration and that higher-concentration electrolytes result in less dead lithium formation and solid carbonate deposition.
