Summary: Practical use of lithium-sulfur batteries can be achieved by using sparingly solvating electrolytes such as [Li(G4)][TFSA] solvate ionic liquid, superconcentrated electrolyte solutions, and their hydrofluoroether-diluted electrolytes. However, the choice of electrolyte affects the battery performance, especially the C-rate characteristics. In this study, the relationship between discharge reaction and battery performance for lithium-sulfur batteries with 1,1,2,2-tertafluoroethyl 2,2,3,3-tetrafluoropropyl ether-diluted [Li(G4)][TFSA] was investigated through in situ electrochemical impedance spectroscopy. The results showed that a voltage drop occurred during discharge at a high C-rate, and the charge transfer resistance of the lithium negative electrode increased significantly when the voltage drop occurred.

Summary: Lithium (Li) composites with Li-ionic conductive Al-doped Li7La3Zr2O12 (LLZO) particles (Li/LLZO) are fabricated using a mechanical kneading process. These composites effectively regulate the Li-ion flux and suppress the Li dendritic growth by creating faster pathways for Li-ion migration. As a result, Li-metal-based cells utilizing the Li/LLZO composite anodes demonstrate significantly enhanced cycle stability compared to cells employing pure Li anodes.

Summary: Solid-state batteries (SSBs) show promise for fast-charging, but face challenges such as electro-chemo-mechanics interaction, interface evolution, and transport-kinetics dichotomy. Critical features like plating-stripping crosstalk, metallic filament growth, cathode microstructure, and interphase formation impact the fast-charge performance of SSBs.

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.
