Summary: Anode-free all-solid-state batteries (AFASSBs) simplify the manufacturing process by eliminating the lithium anode. This study investigates the effects of different solid electrolytes (SEs) on AFASSBs without stack pressure. The results demonstrate that argyrodites enhance Li plating/stripping, while other SEs degrade quickly. Superionic halogen-rich Li-argyrodites, specifically Li5.5PS4.5Cl1.5, show improved capacity and cyclability, indicating their benefit for AFASSBs. The elimination of the initial Li nucleation reaction further enhances the interfacial stability, and the combination of Li5.5PS4.5Cl1.5 and Ag-C achieves the highest coulombic efficiency.

Summary: Lithium-rich antiperovskites (LiRAPs) solid electrolytes have many advantages, but they are hygroscopic and prone to decomposition in air, which limits their application in all-solid-state lithium batteries (ASSLBs). In this study, the hygroscopic behavior of Li3-x(OHx)Cl is investigated and a moisture-resistive Li3-x(OHx)Cl0.9F0.1 is successfully synthesized by fluorine doping. Two prototypes of ASSLBs are assembled using LiRAPs as the solder, demonstrating the feasibility of low-temperature sintering with low interfacial resistance. Understanding the hygroscopicity of LiRAPs and integrating moisture-resistive LiRAPs with ASSLBs provide an effective way to fabricate ASSLBs.

Summary: NiTiNb alloys were fabricated through L-PBF with powder mixtures of prealloyed NiTi and elemental Nb powders. The addition of Nb significantly altered the dependence of MTTs on L-PBF process parameters. The net effect of Nb addition is to lower MTTs, while Ni evaporation has the opposite effect. In NiTiNb3 alloys, factors that promote and suppress MTTs are almost completely compensated, resulting in a rather stable MTT despite variations in L-PBF process parameters.

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.

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.
