All-SOLID-STATE SECONDARY BATTERY

An all-solid-state secondary battery includes: a cathode layer including a cathode active material, an anode layer including an anode current collector and an anode active material layer disposed on the anode current collector, the anode active material layer including an anode active material and amorphous carbon, and a solid electrolyte layer disposed between the cathode active material layer and the anode active material layer, wherein a weight ratio of the anode active material to the amorphous carbon is 1:3 to 1:1, and the anode layer has sheet resistance of about 0.5 milliohms-centimeters or less.
