Solid electrolyte sheet and all-solid-state battery

Abstract

A solid electrolyte sheet includes: a support that is a nonwoven fabric with an average fiber diameter larger than 6.0 μm and less than 16.0 μm, the average fiber diameter including a fiber diameter of a fiber assembly portion in which a plurality of fibers is agglomerated or fused; and a solid electrolyte supported by the support. An all-solid-state battery includes a positive electrode layer, a negative electrode layer, and a solid electrolyte layer disposed between the positive electrode layer and the negative electrode layer. The solid electrolyte layer includes the solid electrolyte sheet.
