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 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: By releasing the elastic and reversible lithium plating interval, superior charging performance and reduced charging duration at low temperatures can be achieved. The plating-weak fast charging (PWFC) strategy effectively avoids rapid degradation by regulating high reversibility and fine-tuning the charging current that triggers the lithium plating.

Summary: Despite rapid technological progress, widespread adoption of battery electric vehicles (BEVs) is hindered by limited driving ranges and long charging times. Efforts to reduce charging times to 15 minutes, similar to refueling times for conventional vehicles, face challenges such as accelerated battery aging and safety hazards during operation. Various approaches have been explored to develop fast charging strategies for battery management systems, but consensus on the optimal solution remains elusive. This review evaluates over 50 studies on fast charging strategy determination, analyzing them based on parameterization efforts, battery types studied, and real-world applicability, to identify research gaps and enable transfer to electric vehicle applications.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
