Document Type and Number:
WIPO Patent Application WO/2023/090449
Kind Code:
A1
Abstract:
According to one embodiment of the present invention, provided is a flexible all-solid-state battery having a weight energy density as high as that of a lithium ion battery that uses a conventional electrolytic solution, and having high safety in which short-circuiting does not occur even when being bent by an excessive bending load. According to one embodiment of the present invention, provided is a flexible all-solid-state battery having a layer of a solid polymer electrolyte disposed between a layer of a separator that holds a solid polymer electrolyte and a layer comprising a negative electrode active material. In this flexible all-solid-state battery, the separator may comprise any one of: a woven fabric, a knitted fabric, or a nonwoven fabric formed of inorganic or polymer fibers in an amount of 1-70 g/m2 and in a thickness of 1-100 μm; an oxide ceramic particle layer that includes oxide ceramic particles at a filling rate in the range of 5-60%, each having a particle size of 1-20 μm; and a composite body of the oxide ceramic particles and the woven fabric, the knitted fabric, or the nonwoven fabric.
