Summary: In this paper, the impedance spectrum of a battery is predicted using the battery charging voltage curve and optimized based on electrochemical mechanistic analysis and machine learning. The internal electrochemical relationships between the charging curve, incremental capacity curve, and the impedance spectrum are explored, improving the physical interpretability and defining the proper partial voltage range for machine learning models. The experimental results show that the predicted errors for impedance spectrum are less than 1.9 mO with the proper partial voltage range selected by the corelative analysis of the electrochemical reactions.

Summary: In this study, a direct recycling process of spent LiFePO4 by direct room temperature chemical lithiation is reported. The characterization of a recovered LFP cathode from a spent commercial battery shows that the end of life of the battery is mainly due to lithium loss, while the structure of the LFP cathode material is preserved. The cathode can be efficiently recovered by direct lithiation in solution using LiI in ethanol, with excellent electrochemical performance and without additional heat treatment.

Summary: This research investigates the impact of heating temperature on the thermal runaway (TR) of lithium-ion batteries (LIBs). It is found that TR occurs when the heating temperature exceeds 200 degrees Celsius, while only safety venting is observed at 175 degrees Celsius. As the heating temperature increases, the time interval between safety venting and TR decreases, and the temperature difference within the battery decreases. Additionally, the contribution of self-generated heat to trigger TR at different heating temperatures is identified.

Summary: A reliable power grid system based on renewable energy sources is crucial to tackle the climate crisis. Stationary battery energy storage systems (BESS) have great potential to mitigate power fluctuations in the grid at different time scales. This study presents an accelerated battery degradation investigation on NCM532/Gr lithium-ion battery cells for single and multi-service applications. Frequency regulation (FR) was found to be the least harmful, with an expected lifetime of 12 years, while peak shaving (PS) resulted in an expected lifetime of 8 years. The combined cycle (FRPS) accelerated capacity loss and induced positive electrode degradation, leading to power limitations after only 870 equivalent full cycles (EFC). Tracking the 1C-rate discharge capacity proved to be a reliable method for evaluating the internal battery state of health (SOH).

Summary: This study reports localized lithium plating in automotive-grade lithium-ion cells, even under mild cycling conditions. Severe lithium plating is typically initiated near the positive tab, leading to substantial capacity fade of the full cells. High pressure during cycling causes electrode expansion and external constraint, resulting in deactivation of components and consequent lithium plating. However, components harvested from regions without lithium plating maintain adequate electrochemical performance.

Summary: Through the use of Li-7-NMR and 2D-XRD techniques, we investigated the properties of hard carbon fibers in different states of charge. We found that at low Li content, Li is distributed in disordered spatial domains, while at high Li content, ordered domains become populated. We also observed the presence of very small metallic lithium particles at high Li content. The joint analysis of XRD and Li-7-NMR revealed a mesoscopic structure composed of ordered domains arranged in a cylindrical manner parallel to the fiber axis.
