    supporting high current densities

## Description

- description: The fabrication of all-solid-state batteries using lithium metal that
    can be operated at high current densities (free lithium dendrites) is a recognized
    worldwide goal. We used a glassy lithium borate (LBO)–based microstructure as
    the grain boundary modifier of a garnet-type solid electrolyte to prevent lithium
    dendrite formation at high current densities. The relative density (90 %) and
    ionic conductivity (10–4 S cm–1) were similar for LBO-modified and non-modified
    solid electrolytes. Notably, a post-annealing step at 175 ◦C significantly reduces
    the interfacial resistance between the LBO-modified electrolyte and lithium metal.
    LBO in the solid electrolyte microstructure distributes the current and prevents
    dendrite propagation, suppressing lithium dendrites up to 10 mA cm–2. Low voltage
    response at a current density of 10 mA cm–2 for 60 galvanostatic plating–stripping
    cycles establishes the fast-charging capability of this composite electrolyte.
    Density functional theory calculations reveal that LBO offers a broader electrochemical
    stability window compared to LLZ, enhancing overall stability within the 0–3.4
    V range. This work provides a promising route to simultaneously achieve high current
    density operation and improved interfacial stability in garnet-based solid-state
    batteries, accelerating the practical implementation of lithium-metal anodes.
