However, accurate RUL estimation is often challenged by data privacy constraints and the significant variability in battery degradation patterns under different operating conditions, making centralized model training impractical. As a solution to the aforementioned issue, the paper suggests a model of federated learning that does not compromise data privacy and allows joint model training to facilitate strong RUL prediction on heterogeneous battery datasets. The NASA Prognostics Center of Excellence (PCoE) lithium-ion battery aging data, comprising eight 18,650 lithium-ion cells is used to conduct experiments. Multivariate discharge signals such as voltage, current, temperature, time and capacity are converted to a time sequence with a sliding window of 30 cycles. RUL is characterized by an end-of-life capacity threshold and tough chronological data partition is utilized to avoid temporal leakage. To simulate distributed satellite environments, two federated configurations are constructed, each consisting of three client batteries for decentralized training and one unseen battery for global evaluation. A CNN-LSTM-Attention regression model is then fine-tuned on every client and a softmax-based adaptive aggregation method, called as FedWeightedAvg, is offered to mitigate the issue of client heterogeneity by providing greater aggregation weights to the better performing local models. The experimental results show that the proposed method is better in terms of robustness and global prediction error than the standard FedAvg algorithm. The proposed FedWeightedAvg strategy is able to obtain the smaller RMSE equal to 0.1856 in the relatively homogeneous subgroup and 0.6539 in the heterogeneous subgroup, compared to the conventional FedAvg aggregation method. Such findings suggest that adaptive federated aggregation and hybrid deep learning temporal model is an accurate, privacy-preserving, and scalable predictive control over lithium-ion battery RUL in distributed satellite prognostics systems.</p></div>","PeriodicalId":599,"journal":{"name":"Ionics","volume":"32 9","pages":"9335 - 9360"},"PeriodicalIF":3.4,"publicationDate":"2026-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148927997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This porous material served as an electrode for lithium-ion batteries and was evaluated against commercial graphite under identical conditions. And the structure-activity relationship between its high capacity, superior rate capability and material is clarified.

At 1 A g⁻¹, it maintained a capacity of 192.12 mAh g⁻¹, superior to graphite’s 53.53 mAh g⁻¹, showing excellent rate capability. The high reversible capacity and superior rate capability stem from the synergistic interplay among its unique disordered microstructure, large interlayer spacing, and extensive pore network, all of which synergistically support the lithium storage mechanism of hard carbon materials.

The structural and optical properties were analyzed by XRD, FTIR, photoluminescence (PL), SEM and UV-Visible spectroscopy. XRD analysis suggests the phase purity of the synthesized materials and the coexistence of diffraction peaks corresponding to both CaFe₁₂O₁₉ and LaNiO₃ in the composite samples. The average crystal size of the synthesized material is in the range of 13.30 to 15.48 nm. From the FTIR analysis, prepared nanoparticles and composite contain all the required functional group. The PL analysis was employed to estimate the recombination rate which is essential for degradation mechanism. Reduction in the PL intensity may attribute to the enhanced charge separation by reducing the recombination rate. The increased charge separation is good for excellent photocatalytic properties and improves the efficiency of the degradation mechanism. The UV-Visible spectroscopic analysis was employed to determine the optical band gap. The reduction in band gap from 2.7 to 1.78 eV pointedly contributes to efficient degradation. In this study, Cefoperazone-Salbactam sodium was used as a model pollutant to determine the degradation efficiency of CaFe₁₂O₁₉ and composite with LaNiO₃. The degradation activity findings shows that efficiency of nanocomposite was increased from 47 to 93% for Cefoperazone and 56 to 95% for Salbactam sodium under visible light. Moreover, scavenging experiment was conducted to analyze the main reactive species in the photocatalytic mechanism as well as recycling experiment was performed to check the stability.

Herein, we report hierarchical, wrinkled honeycomb-like ternary cobalt-molybdenum-zinc sulfide nanosheet networks in-situ grown on 3D nickel foam (denoted as Co₁Mo₁Zn₁-S/NF) via a two-step hydrothermal strategy. This unique ternary sulfide architecture leverages potent electronic synergistic interactions. The strategic incorporation of Zn and Mo effectively modulates the electronic structure of Co centers, lowers redox activation energy, and optimizes the d-band center, while facilitating precise electron density regulation through multi-metal charge redistribution. Significant XPS binding energy shifts confirm this robust electronic coupling, which provides abundant redox-active sites and accelerates interfacial charge transfer kinetics. Benefiting from a high electroactive surface area and the “ion-buffering reservoir” effect of mesoporous nanosheets, the Co₁Mo₁Zn₁-S/NF electrode delivers an exceptional specific capacitance of 2404 F g^− 1 at 2 A g^− 1 with 73.21% retention at 50 A g^− 1.

Notably, the device retains 78% of its initial capacitance after 10,000 cycles. This robust stability is primarily ascribed to the “lattice anchoring” effect of Zn and Mo, which mitigates structural degradation during continuous ion intercalation/deintercalation.
