Abstract

All-solid-state Li metal batteries with ultimate energy density require stabilization at the Li/solid electrolyte interfaces. Further, the use of conventional thick (hundreds of μm) Li metal anodes (LMAs) hinders an impartial evaluation of full cells. In this study, interfacial evolution is compared for thin LMAs (∼ 10 μm thick) prepared by a scalable electrodeposition, with varying protective In/Li_xIn layer formed via electroless plating. The positive effects of the In/Li_xIn layer are confirmed for both Li/Li₆PS₅Cl/Li symmetric cells and LiNi_0.70Co_0.15Mn_0.15O₂/Li₆PS₅Cl/Li full cells. Complementary analysis including electrochemical, ex situ X-ray photoelectron spectroscopy, operando electrochemical pressiometry, and cross-sectional scanning electron microscopy measurements discloses complex Li/Li₆PS₅Cl interfacial evolutions affected by the In/Li_xIn coatings, that is, suppressed side reactions and penetrating Li growth. Importantly, a new indicator from operando electrochemical pressiometry analysis, the capacity-normalized pressure change difference Δ(ΔP_Q) successfully predicts the dendritic growth of Li during cycling of LiNi_0.70Co_0.15Mn_0.15O₂/Li full cell.
