However, the estimation of the State of Health (SOH) for LIBs under fast charging conditions has received relatively little attention. Therefore, a data-driven and improved incremental capacity analysis-based SOH estimation model for LIBs is proposed in this paper, which can estimate the SOH at different charging rates. Firstly, a revised Lorentz voltage capacity (RL-VC) model is constructed using the constant current charging data. Further, the revised Lorentz incremental capacity (RL-IC) curve of the battery is calculated and decomposed according to the RL-VC model. Then, the health features (HFs) are extracted from the original and the decomposed RL-IC curves. The HFs with high correlation are selected through Pearson correlation analysis as inputs to the back-propagation neural network to build the SOH estimation model. Validation of the model is performed on NASA datasets containing one charging rate and experimental datasets with three charging rates. The results indicate that the proposed model can estimate the SOH of LIBs more accurately than the estimation models in the recent literature. The SOH estimation errors are all less than 1 %, and the coefficients of determination are all higher than 0.98 in Hold-out cross validation. It also shows excellent generalization ability under different charging rates.</div></div>","PeriodicalId":100560,"journal":{"name":"Future Batteries","volume":"6 ","pages":"Article 100074"},"PeriodicalIF":0.0,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143894880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this issue, it is crucial to integrate sufficient engineered void space within the silicon composites and to effectively and uniformly coat the particles with carbon. Herein, we propose a straightforward method to address both concerns. The template synthesis approach, utilizing sodium chloride as a sacrificial template, creates an internal void network, while a double carbon coating with pyrrole enhances electrical conductivity and stabilizes the microstructure. A single pyrrole carbon coating on the silicon anode yields a delithiation capacity of 480 mAh g⁻¹. However, when an additional carbon layer is applied, the delithiation capacity increases significantly, reaching up to 670 mAh g⁻¹ after 180 cycles. This indicates that the additional carbon layer not only enhances the electrical properties but also provides structural support, resulting in improved performance and longevity of the silicon anode. The synthesis strategy presented here has the potential to significantly improve the performance of silicon-based anodes, paving the way for the development of advanced silicon materials for the next generation of lithium-ion batteries. This method offers a promising solution to one of the major challenges in battery technology, providing a pathway towards higher capacity and more stable battery systems.</div></div>","PeriodicalId":100560,"journal":{"name":"Future Batteries","volume":"6 ","pages":"Article 100069"},"PeriodicalIF":0.0,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143833726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The graphene deposition process employs cyclic voltammetry (CV) in a 5 M HNO3 (Nitric Acid) solution. Introducing graphene oxide (GO) into the system before CV enables a more substantial conversion of graphite to RGO, enhancing the electrode’s performance and stability under VRFB working conditions, surpassing the efficacy of electrodes pretreated using a basic water washing method.

Advancements in EV charging technology focus on developing power converters with higher DC-link voltages (800V-1000V) and multilevel topologies. This paper explores a full-bridge five-level Flying Capacitor (FC) converter using hybrid silicon and Wide Bandgap (WBG) devices for EV charger grid connections. A key challenge in FC converters is maintaining floating capacitor voltage balance while minimizing power losses. Although higher switching frequencies reduce voltage fluctuations, they increase switching losses. WBG devices, with their high band gaps and low switching losses, address this issue effectively. Thermal analysis of the converter is conducted using PLECS software, comparing Si-IGBT, SiC MOSFET, and GaN MOSFET. The paper proposes a novel multilevel PWM scheme that combines Phase-Disposition (PD) PWM and Phase-Shift (PS) PWM. This hybrid approach enhances waveform quality and improves thermal performance by reducing losses in specific components. To address the high cost of WBG devices, a hybrid strategy is suggested, replacing high-loss components with WBG devices while retaining silicon devices elsewhere. The study identifies optimal switch combinations based on loss analysis using practical data and thermal models. Results highlight trade-offs between cost and performance, presenting a cost-effective solution for high-performance FC converters.
