Summary: This paper introduces a novel fast charging procedure that reduces the deposition of metallic lithium on the surface of the negative electrode by regulating the current through the correlation between electrode polarization and anode potential. The linear relationship between cell voltage and anode potential is shown independently of current rate, temperature, and initial SOC. By implementing anode potential regulation based on this relationship, the risk of unwanted lithium plating is significantly reduced. The advantage of this implementation is that it does not require a P2D model on a micro-controller, making it suitable for embedded systems.

Summary: This work investigates the electrochemical impedance spectroscopy (EIS) characteristics of lithium-ion batteries (LIBs) under practical usage conditions. The validity of the EIS data is quantitatively assessed based on the theoretical framework of operando odd random phase EIS (ORP-EIS). The results reveal the continuous evolution of charge-transfer phenomena along changes of state-of-charge (SoC) and the extracted parameters exhibit consistent behavior under various charging conditions. The operando ORP-EIS provides unique physical insights and could be a powerful technique for monitoring the state-of-charge (SoC) of batteries during fast charging.

Summary: To address the issue of lithium (Li) plating on graphite anodes during fast charging, Li plating regulation and morphology control are proposed. A Li plating-reversible graphite anode is achieved through a localized high-concentration electrolyte (LHCE), resulting in high reversibility and stability. The stable LiF-rich solid electrolyte interphase (SEI) enables a higher average Coulombic efficiency (99.9%) and reversibility of Li plating (99.95%). A self-made LiNi0.5Mn0.3Co0.2O2 | graphite pouch cell exhibits a competitive capacity retention of 84.4% even at high current (7.2 A) after 150 cycles, demonstrating the potential for high-performance fast-charging batteries.

Summary: In recent years, significant efforts have been made to find a fast-charging method for lithium-ion batteries (LIBs), which can be widely used in electric vehicles. The research focuses on suppressing lithium (Li) plating on the graphite anode, as it causes capacity deterioration and safety issues under fast-charging conditions. This study presents mechanistic insights into pulse-current-based fast-charging, which effectively inhibits Li plating on the anode by redistributing Li+ species at the electrolyte/anode interface periodically.

Summary: This paper compares two types of switched reluctance machines (SRMs) and SRM converters. The comparison is between an SRM with a segmental rotor and a conventional SRM, as well as between an SRM converter with a passive boost circuit and a conventional asymmetric half-bridge converter. The comparison is conducted in simulation and validated through experimental results. The experimental results demonstrate that the segmental SRM can reduce torque ripple by a maximum of 7% in the low-speed range compared to the conventional SRM. With the boost converter, both the conventional SRM and the segmental SRM can achieve lower torque ripple and higher maximum speed.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
