Title:
MULTI-STACK MONOPOLAR ALL-SOLID-STATE BATTERY
Document Type and Number:
WIPO Patent Application WO/2021/025418
Kind Code:
A1
Abstract:
The present invention relates to an all-solid-state battery, which comprises a plurality of monopolar units disposed in parallel in a pouch cell, each of the monopolar units comprising: a solid electrolyte layer; a positive electrode layer attached to one side of the solid electrolyte layer; and a negative electrode layer comprising a negative electrode metal body attached to the other side of the solid electrolyte layer and a negative electrode current collector layer to which the negative electrode metal body is attached, wherein the positive electrode layer has both surfaces casted of a positive electrode active material, and thus can be shared by the monopolar units adjacent to each other. Therefore, the all-solid-state battery of the present invention has a reduced size and volume compared with bipolar stack type all-solid-state batteries with simple stacking structures, and thus can be used for various purposes, increase the capacitance to volume, and can provide a multi-stack monopolar type all-solid-state battery allowing up to ESS capacitance.
