Summary: Solid-state lithium metal batteries (SSLMBs) have potential for high safety and energy density, but the growth of lithium dendrite in solid electrolytes limits their practical applications. This study develops a simple heat treatment method to revive and recycle garnet oxide electrolytes with Li dendrite penetration. The recovered garnet electrolyte shows higher relative density, enhanced ionic conductivity, and improved critical current density compared to the pristine one. Thermal healing is attributed to the reaction products between dendritic Li metal and air, contributing to further densification of garnet electrolytes during heat treatment.

Summary: The solid electrolyte interphase (SEI) plays a critical role in determining the interfacial stability of lithium metal anode. Research compared a diluted electrolyte and a super-concentrated electrolyte, finding that the latter results in a more compact SEI structure due to reduced solubility and outstanding formation kinetics. This work provides new insights into the superior performance of super-concentrated electrolyte in lithium metal batteries.

Summary: In this study, a poly(ether block amide) (PEBA) based polymer electrolyte with lithium bis-(trifluoromethanesulfonyl)imide (LiTFSI) as the Li salt is developed, which possesses good ion conductivity and suppresses the growth of Li dendrites. The electrolyte provides abundant amide groups to activate TFSI- anions and further enriches lithium fluoride (LiF) content in the SEI layer, resulting in improved cyclability and long-life span of the full-cell battery. Therefore, the PEBA based electrolyte shows great potential for solid-state lithium metal batteries.

Summary: Lithium metal batteries (LMBs) are known for their high energy density and low redox potential, but they face a major issue with lithium dendrites. Gel polymer electrolytes (GPEs) have emerged as a promising solution, thanks to their good interfacial compatibility, comparable ionic conductivity to liquid electrolytes, and improved interfacial tension. This review examines the mechanisms and advantages of GPEs in suppressing lithium dendrites, explores the relationship between GPEs and solid electrolyte interfaces (SEIs), and summarizes the effects of GPE preparation methods, plasticizer selections, polymer substrates, and additives on the SEI layer. The challenges and prospects of using GPEs and SEIs for dendrite suppression are also discussed.

Summary: In this study, an asbestos (ASB) functionalized solid polymer electrolyte (SPE) is introduced to facilitate even lithium deposition and suppress lithium dendrite growth. The ASB functionalized SPE enhances the ionic conductivity and Li+ transference number, resulting in improved cycling stability and discharge capacity of LiFePO4 batteries. The even and smooth surface morphology of Li metal after cycling using the ASB functionalized SPE demonstrates the successful inhibition of dendrite growth. Therefore, the ASB functionalized SPE proposes a prospective strategy for restraining lithium dendrite.

Summary: The study revealed that the tungsten surface layer after helium implantation is composed of compressed, transition, expanded, and matrix zones. The compressed zone became thinner after helium implantation possibly due to the formation of He-complexes, while the expanded zone resulted from helium atoms entering the tungsten lattice. The transition zone is a result of competition between the expanding and compressing effects.

Summary: This study characterizes the tensile properties and microstructure changes of tempered 9Cr-F/M steel under different stress states using various microscopy techniques. It was found that the strength of the steel decreases at elevated temperatures, but the elongation at 400 degrees Celsius is lower than that at room temperature. Tensile deformation causes grain elongation in the direction of applied stress and reduces the grain's cross-section. The deformation in the transverse direction is more severe than that in the normal direction for samples with rectangular working area cross-section, resulting in grain elongation in the transverse direction.

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.
