Title: Mastering the interface for advanced all-solid-state lithium rechargeable batteries

Abstract

A solid electrolyte with a high Li-ion conductivity and a small interfacial resistance against a Li metal anode is a key component in all-solid-state Li metal batteries, but there is no ceramic oxide electrolyte available for this application except the thin-film Li-P oxynitride electrolyte; ceramic electrolytes are either easily reduced by Li metal or penetrated by Li dendrites in a short time. In this paper, we introduce a solid electrolyte LiZr 2(PO4) 3 with rhombohedral structure at room temperature that has a bulk Li-ion conductivity σ Li = 2 × 10 -4 S∙cm -1 at 25 °C, a high electrochemical stability up to 5.5 V versus Li +/Li, and a small interfacial resistance for Li + transfer. It reacts with a metallic lithium anode to form a Li +-conducting passivation layer (solid-electrolyte interphase) containing Li 3P and Li 8ZrO 6 that is wet by the lithium anode and also wets the LiZr 2(PO 4) 3 electrolyte. Finally, an all-solid-state Li/LiFePO 4 cell with a polymer catholyte shows good cyclability and a long cycle life.
