Original Abstract Submitted
an all-solid-state secondary battery includes a cathode layer, an anode layer, and a solid electrolyte layer between the cathode layer and the anode layer, wherein the cathode layer includes a cathode current collector and a cathode active material layer on at least one side of the cathode current collector, the anode layer includes an anode current collector and a first anode active material layer on at least one side of the anode current collector, the first anode active material layer includes an anode active material capable of forming an alloy or compound with lithium, a fibrous carbon-based material, and a binder, a ratio (b/a) of an initial charge capacity (b) of the first anode active material layer to an initial charge capacity (a) of the cathode active material layer is about 0.01 to about 0.75.
