Summary: LiMnPO4 and LiMn1-xLaxPO4 (0.01 <= x <= 0.1) nanostructures with in-situ carbon coating were synthesized by low temperature solvothermal method using Glycerol: Water (2:1) ratio as solvent. X-ray diffraction studies confirmed the orthorhombic crystal structure of LiMnPO4 and LiMn0.99La0.01PO4. The electrochemical tests showed that 1% La3+ ion doped LiMnPO4 could be a promising cathode material to improve the electrochemical stability of Lithium-ion cells at higher C-rate.

Summary: In this study, the capacity of graphene|electrolyte|Li laboratory cell was tested at different currents. The impedance of the Li4Ti5O12|electrolyte|Li laboratory and commercial Li-ion cells was also measured. The research discusses various factors that affect Li-ion batteries, such as cathode and anode material capacity, battery polarization, heat dissipation, volume changes, capacity under non-equilibrium conditions, pseudocapacitive behavior, and battery safety. The results show that battery capacity may vary with current and polarization, and the measurement process may affect the determined capacity value.

Summary: In this study, a new cationic semi-interpenetrating polymer network (c-IPN) binder is proposed to regulate electrostatic phenomena and improve the performance of high-capacity positive electrodes for Li metal batteries. The c-IPN binder suppresses crack evolution and improves the dispersion state of electrode components by surface charge-driven electrostatic repulsion and mechanical toughness. It also immobilizes anions of liquid electrolytes inside the electrodes via electrostatic attraction, facilitating Li+ conduction and forming stable cathode-electrolyte interphases.

Summary: This study explores the effect of Mn substitution in NaFe1-yMnyPO4 on the electrochemical performance. The results show that increasing the Mn content improves the average discharge voltage but reduces the capacity. However, an optimal composition of y = 0.2 is identified for energy density and efficiency of the Fe2+/Fe(3+) reaction. The reaction mechanism of NaxFe0.8Mn0.2PO4 involves two intermediate phases with extended solubility limits, which can buffer the volume mismatch of the system. The Na-rich phase Na0.73+beta Fe0.8Mn0.2PO4 is thermodynamically stable with charge order, while the Na-poor phase Na0.2+gamma Fe0.8Mn0.2PO4 is kinetically induced.

Summary: The study demonstrates that thermal nanocrystallization of glassy analogs of LiFe1-xMnxPO4 results in highly conducting materials suitable for use as cathodes in Li-ion batteries. The electrical conductivity of the nanocrystalline samples varied depending on composition, with the conductivity of x=0.5 samples exceeding 10-3 S/cm at room temperature. The increase in conductivity was explained by Mott's theory of electron hopping and a core-shell concept.

Summary: In recent years, digital twins for large-scale and investment-intensive Li-ion battery systems in marine and stationary applications have gained increasing interest. Considering electrical cell-to-cell variations (CtCVs) within the battery model of such a digital twin offers advantages in model-based optimization and predictive maintenance. However, existing approaches for the characterization and modeling of CtCVs are not suitable for large-scale systems. This paper presents a holistic tool chain consisting of a non-destructive method for in-situ determination of resistance and capacity distributions, parameterization of a multi-cell battery model, and simplification through multivariate statistical analysis.

Summary: Large-scale battery energy storage systems (BESS) are already important in ancillary service markets worldwide, with batteries being suitable for applications with fast response times. However, the overall system response time of current BESS for future grid services has not been extensively studied. Measurements of a 6 MW BESS's inverters show that the response times can meet current standards even with older hardware, but hardware upgrades may be necessary for even faster future grid services.

Summary: This paper proposes a machine learning-based fast charging strategy for lithium-ion batteries. By using a reduced-order electrochemical-thermal model in the cloud, the soft actor-critic deep reinforcement learning algorithm is exploited to train the strategy. Hardware-in-Loop tests and experiments show that the proposed strategy effectively mitigates risks and improves the safety and longevity of batteries during fast charging. Compared to the commonly-used empirical protocol, the proposed approach extends the battery cycle life by about 75%.

Summary: Electric vehicles are becoming dominant in the global automobile market due to their environmental friendliness. This paper creates standard load profiles for different power levels, station sizes, and operating environments based on a large-scale empirical dataset. The study reveals that the average power per charge point increases with rated station power, especially for power above 100 kW, and decreases with the number of charge points per station for AC chargers. It also shows how the shape of the power curve largely depends on the station environment, with urban settings experiencing the highest average power of 0.71 kW on average, resulting in an annual energy sale of 6.2 MWh. These findings suggest that the rated grid capacity can be lower than the sum of the rated power of each charge point.

Summary: An accurate estimation of the residual energy, State of Energy (SoE), is crucial for battery diagnostics in electric vehicles. Existing literature lacks in-depth analysis and comparison of SoE estimation methods. This work provides a comprehensive understanding of SoE by discussing various definitions and estimation approaches. Two physically feasible definitions are proposed, and the practical challenges of SoE estimation are critically analyzed. Experimental evaluation highlights the underestimation of residual energy by the State of Charge, emphasizing the importance of accurate SoE estimation.

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.
