Document Type and Number:

WIPO Patent Application WO/2022/254284

Kind Code:

A1

Abstract:

Provided is a secondary battery that has good interfacial contact between an active material and an electrolyte. The secondary battery has a positive electrode layer, a negative electrode layer, and an electrolyte layer located between the positive electrode layer and the negative electrode layer. The positive electrode layer has a positive-electrode active material and a first solid electrolyte. The negative electrode layer has a negative-electrode active material and a second solid electrolyte. The electrolyte layer has a third solid electrolyte and an ionic liquid. The ionic liquid is impregnated in gaps in the third solid electrolyte. The secondary battery is bendable.
