8 Claims

1. A method for manufacturing an electrode for an all solid-state battery, comprising the steps of:

preparing a slurry for forming an electrode active material layer containing electrode active material particles, a polymeric solid electrolyte and a conductive material;

coating the slurry on at least one surface of a current collector to obtain a preliminary electrode; and

subjecting the preliminary electrode to a solvent annealing process, in which the polymeric solid electrolyte is exposed to a vaporized organic solvent and the vaporized organic solvent infiltrates into the solid electrolyte to cause volumetric swelling of the electrolyte, to obtain an electrode.
