Abstract
(EN)
The present invention provides a method for producing a solid-state battery, which enables a solid electrolyte layer and an electrode to be sufficiently in close contact with each other without deformation of the shape of or damage to the electrode. The method for producing a solid-state battery, according to the present invention, is characterized by producing a solid electrolyte layer by patterning a solid electrolyte layer slurry, applying the solid electrolyte layer slurry onto the surface of an electrode active material layer, and then performing pressurization.

La présente invention concerne un procédé de production d'une batterie à électrolyte solide permettant d'obtenir un contact suffisamment étroit entre une couche d'électrolyte solide et une électrode sans déformation ni endommagement de l'électrode. Selon la présente invention, ce procédé de production d'une batterie à électrolyte solide est caractérisé par la production d'une couche d'électrolyte solide par formation d'un motif sur une suspension épaisse de couche d'électrolyte solide, application de la suspension épaisse de couche d'électrolyte solide sur la surface d'une couche de matériau actif d'électrode, puis réalisation d'une mise sous pression.
