Abstract

Solid-state batteries with alkali metal anodes offer high energy density and improved safety, but their performance is hindered by void formation at the metal-solid electrolyte interface during discharge. These voids lead to contact loss and impedance rise, and increase the probability of dendrite formation upon plating. While high stack pressures (≥1 MPa) can suppress voiding, they impose engineering constraints that reduce pack-level energy density. In this work, we demonstrate that adding low concentrations (
