ALL-SOLID-STATE BATTERY USING LITHIUM METAL AS NEGATIVE ELECTRODE

Title:

ALL-SOLID-STATE BATTERY USING LITHIUM METAL AS NEGATIVE ELECTRODE

Document Type and Number:

WIPO Patent Application WO/2020/040533

Kind Code:

A1

Abstract:

The present invention relates to a safety-improved electrode assembly for an all-solid-state battery, the novel-structured electrode assembly being designed so that a solid electrolyte layer is not damaged by the formation of a stepped portion even when the stepped portion is formed on a negative electrode layer due to a change in the thickness of the negative electrode layer such as an increase/decrease in the thickness of one portion of the negative electrode layer resulting from charging/discharging. The electrode assembly has a protection layer, comprising an opening part, interposed between a negative electrode and the solid electrolyte layer.
