Abstract

A dry cathode film includes a first dry cathode active material layer adjacent to a cathode current collector, and a second dry cathode active material layer on the first dry cathode active material layer. The first dry cathode active material layer and the second dry cathode active material layer each independently include a dry cathode active material including a composite of Li₂S, a lithium salt, and a carbon-based material; a dry sulfide-based solid electrolyte; and a dry binder. A content of the dry cathode active material in the first dry cathode active material layer is greater than a content of the dry cathode active material in the second dry cathode active material layer, and a content of the dry sulfide-based solid electrolyte in the first dry cathode active material layer is less than a content of the dry sulfide-based solid electrolyte in the second dry cathode active material layer.
