METHOD OF PRODUCING ALL-SOLID-STATE BATTERY

A method of producing an all-solid-state battery comprises preparing a second slurry which is a solid electrolyte slurry, and applying the second slurry to a foundation layer using a die head to form a solid electrolyte layer. A pressure P of the second slurry and a viscosity η of the second slurry inside the die head at a predetermined shear rate satisfy a relationship of P/4η
