Abstract Despite the potentially higher energy density and improved safety of solid-state batteries (SSBs) relative to Li-ion batteries, failure due Li-filament penetration solid electrolyte subsequent short circuit remains a critical issue. Herein, we show that growth is suppressed in solid-electrolyte pellets with beyond ~95%. Below this threshold value, however, battery shorts more easily as increases faster within percolating pores pellet. The microstructural properties (e.g., pore size,...
Abstract Machine learning (ML) has become a valuable tool to assist and improve materials characterization, enabling automated interpretation of experimental results with techniques such as X-ray diffraction (XRD) electron microscopy. Because ML models are fast once trained, there is key opportunity bring in-line experiments make on-the-fly decisions achieve optimal measurement effectiveness, which creates broad opportunities for rapid information extraction from experiments. Here, we...
Abstract Lithium metal solid‐state batteries (LMSSBs) have demonstrated their high energy density and cycling performance at current densities in an anode‐free architecture, featuring a thin Ag/C composite buffer layer (BL) between the collector (CC) solid electrolyte (SE). This study explains microscopic mechanism of BL by using first‐principles atomistic continuum modeling. It is shown that Ag effectively acts as homogeneous solid‐solution beyond AgLi 2.32 maintains positive potential even...
Abstract Nickel-based superalloys and near-equiatomic high-entropy alloys containing molybdenum are known for higher temperature strength corrosion resistance. Yet, complex solid-solution offer a huge design space to tune optimal properties at slightly reduced entropy. For refractory Mo-W-Ta-Ti-Zr, we showcase KKR electronic structure methods via the coherent-potential approximation identify over five-dimensional with improved mechanical necessary global (formation enthalpy) local...
Advancement of solid state electrolytes (SSEs) for all batteries typically focuses on modification a parent structural framework improved conductivity, \textit{e.g.} cation substitution an immobile ion or varying the concentration mobile ion. Therefore, novel frameworks can be disruptive by enabling fast conduction aided different structure and diffusion mechanisms, unlocking optimal conductors with properties (\textit{e.g.} mechanical properties, sintering needs, electrochemical stability)...
Halides are promising solid-state electrolytes for all-solid-state lithium batteries due to their exceptional oxidation stability, high Li-ion conductivity, and mechanical deformability. However, practicality is limited by the reliance on rare expensive metals. This study investigates Li2MgCl4 inverse spinel system as a cost-effective alternative. Molecular dynamics simulations reveal that disordering at elevated temperatures significantly reduces activation energy in Li2MgCl4. To stabilize...
