Title:
NONWOVEN FABRIC AND SOLID ELECTROLYTE LOADED SHEET
Document Type and Number:
WIPO Patent Application WO/2021/229981
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a solid electrolyte loaded sheet which is loaded with solid electrolyte particles in the spaces between fibers, and which is capable of achieving a good balance among reduction in the thickness, fall-off of the solid electrolyte particles and electrical conductivity; and a nonwoven fabric which is suitable for the formation of this solid electrolyte loaded sheet. A nonwoven fabric according to the present invention is characterized by satisfying 0.25 ≤ (L2/V) ≤ 10, where L (μm) is the average fiber diameter of all fibers and V is the volume (cm3) per 1 m2; and it is preferable that this nonwoven fabric contains fibers having a fiber diameter of 1.0 μm or less and fibers having a fiber diameter of more than 1.0 μm.
