All-Solid-State Battery Operable at Room Temperature and Low Pressure and Method of Manufacturing the Same

A method of manufacturing an all-solid-state battery, the method comprising:

• forming a first layer by applying a solution comprising an electrically conductive material to a substrate;
• forming a second layer by depositing a metal capable of alloying with lithium on the first layer;
• and
• manufacturing a stack comprising an anode current collector, a buffer layer disposed on the anode current collector and comprising the first layer and the second layer, a solid electrolyte layer disposed on the buffer layer and comprising a solid electrolyte, a cathode active material layer disposed on the solid electrolyte layer, and a cathode current collector disposed on the cathode active material layer.
