Summary: Rechargeable lithium batteries have transformed energy storage technology, but their further commercialization is hindered by short lifetime and safety issues, mainly due to the unstable solid-electrolyte interphase (SEI) and uncontrolled lithium dendrite growth. Research on SEI worldwide has focused on its debated structure and composition, particularly the role of the main component LiF. This review covers the development history of the SEI model, fundamental understanding of SEI, categorization of anode materials generating LiF in SEI, characterization techniques of SEI layers, transport mechanism of Li+ ions within SEI, physical properties of LiF, and analysis of LiF sources, offering insights for future research directions to promote large-scale applications of lithium metal batteries.

Summary: In the last two decades, extensive research has been conducted on direct alcohol fuel cells (DAFCs) as potential on-demand power sources. Two leading technologies, proton exchange membranes (PEMs) and anion exchange membranes (AEMs), have emerged for acidic and alkaline DAFCs respectively. This review analyzes the current state-of-the-art in acidic and alkaline DAFCs using methanol and ethanol as fuels, with a focus on the effect of reaction stoichiometry. It highlights the participation of hydroxyl ions (OH-) and the presence of anions as alcohol oxidation products in alkaline systems, which are important considerations for fuel design and energy evaluation from a whole system perspective.

Summary: Based on ab initio structure searches using evolutionary algorithms, we explored the LaF3-LaX3 (X=Cl, Br, I) system and predicted the structures of LaF2X and LaFX2 (X=Br, I) compounds. LaF2Br and LaFI2 were successfully synthesized and LaF2I showed similar structure but different layer stacking. LaF2I exhibits fluoride ion conductivity comparable to that of non-doped LaF3 and has the potential for better ionic conductivity with appropriate doping. This study demonstrates that structure prediction using evolutionary algorithms can accelerate the discovery of mixed-anion compounds, particularly those with an ordered anion arrangement.

Summary: A novel concept of solid electrolyte interphase (SEI)-ization of Mg2+-blocking layers has been introduced to improve the deposition quality of Li in anode-free rechargeable Li-metal batteries. Thin, dense, and stable surface layers exhibiting permeability for Li+ and impermeability for Mg2+ ions were formed in Li-Mg electrolytes, significantly suppressing the Li dendrite growth and enhancing the deposited Li metal/Cu CC surface binding. The Mg2+-blocking layers acted as effective SEI layers, positively influencing the electrochemical performance of the AFLMB full cells.

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.
