Manufacturing method for all-solid-state lithium secondary battery

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

• coating a first electrode slurry on a base film proceeding in a roll-to-roll manner, performing a first heat treatment, and performing first pressurization to form a first electrode layer;
• coating a solid electrolyte slurry on the first electrode layer, performing a second heat treatment, and performing second pressurization to form a solid electrolyte layer;
• and
• coating a second electrode slurry on the solid electrolyte layer, performing a third heat treatment, and performing third pressurization to form a second electrode layer,
• wherein the first electrode is a positive electrode, and the second electrode is a negative electrode, or
• the first electrode is a negative electrode, and the second electrode is a positive electrode.
