ALL-SOLID-STATE BATTERY COMPRISING COMPOSITE ELECTRODE

Disclosed is an all-solid-state battery comprising an electrode assembly and a solid electrolyte, wherein the electrode assembly comprises a structure in which plate-shaped electrodes are stacked; and the electrodes include a relatively high heat-generating first electrode and a relatively low heat-generating second electrode, wherein the first electrode is disposed in a center of the electrode assembly, the all-solid-state battery with improved performance by increasing the temperature of the battery without adding additional members.
