Abstract Lithium‐ion batteries (LIBs) with ternary oxide cathode materials are the prevalent energy storage devices for electric vehicles, and huge amounts of spent LIBs pose severe challenges in terms environmental impact resource management. Particularly, proper handling degraded is central importance sustainable closed‐loop development industry. In this context, direct regeneration oxides toward reusable high‐performance environmentally economically favorable contrast to present metallurgical recycling methods. work, a simple effective two‐step method demonstrated regenerate NCM 622 (LiNi 0.6 Co 0.2 Mn O 2 ) by elemental compensation structural restoration. Moreover, multi‐functional LTO (Li 4 Ti 5 12 surface coating simultaneously designed guarantee rapid Li + diffusion stable regenerated product. Therefore, LTO‐coated show excellent electrochemical performance; specifically, initial discharge capacity (183.0 mAh g −1 at 0.1 C), rate capability (90.0 10 cycling stability (79.3% retention after 200 cycles) even comparable those fresh materials. The as‐established upcycling strategy may shed light on value‐added thereby virtuous cycle LIBs.

This work presents an adaptive transfer learning approach for predicting the aging of lithium-ion batteries (LiBs) in electric vehicles using capacity fade as metric battery state health. The proposed includes a similarity-based and strategy which selected data from original dataset are transferred to clean based on combined/weighted similarity contribution feature stress factor similarities times series similarities. Transfer (TL) is then performed by pre-training model with data, frozen weights biases hidden layer. At same time, toward output node recalculated target data. error reduction lies between −0.4% −8.3% 20 computational experiments, attesting effectiveness robustness our TL approach. Considerations structure representation presented, well workflow enhance application LiBs.

This study proposes an efficient, cost-effective, and industrially scalable electrode modulation strategy, which involves directly adding a small amount of high thermal conductance TiN well interface compatible WO3 to NaNi1/3Fe1/3Mn1/3O2 (NaNFMO-TW) cathode slurry, effectively reduce polarization side reactions, the Ohmic heat battery, ultimately significantly improve sodium-ion storage safety performance battery. At room temperature (RT) 1C rate, modified NaNFMO-TW exhibits reversible capacity ∼95 mAh g-1 after 300 cycles, with retention rate 82.6%, being higher than 50.7% for NaNFMO. Furthermore, assembled pouch battery retains 58.2% cycles at RT&0.5C, conspicuously superior 46.1% achieved by NaNFMO||HC In particular, adiabatic tests infrared imaging reveal marked improvement in reduction surface ∼1.3 ∼2.2 °C during 3C charging discharging, respectively. Moreover, results confirmed enhancement mechanism NaNFMO addition WO3. Such strategy provides practical method improving performance.
