Abstract
Official abstract text for this publication.
An active material, a solid electrolyte, and a solvent are hard-kneaded to prepare a first electrode material. A dispersion promotion component is added to the first electrode material to prepare a second electrode material. Slurry containing the second electrode material is prepared. An electrode is produced by applying the slurry to a surface of a base material. A composite body is formed by the solid electrolyte adhering to a surface of the active material. The dispersion promotion component promotes dispersion of the solid electrolyte in the solvent.
First claim
Opening claim text (preview).
What is claimed is: 1 . An electrode production method comprising: (a) hard-kneading an active material, a solid electrolyte, and a solvent to prepare a first electrode material; (b) adding a dispersion promotion component to the first electrode material to prepare a second electrode material; (c) preparing slurry containing the second electrode material; and (d) producing an electrode by applying the slurry to a surface of a base material, wherein: a composite body is formed by the solid electrolyte adhering to a surface of the active material in the (a); and the dispersion promotion component promotes dispersion of the solid electrolyte in the solvent. 2 . The electrode production method according to claim 1 , wherein the (b) includes storing the second electrode material. 3 . The electrode production method according to claim 1 , wherein: the solid electrolyte contains a sulfide solid electrolyte; and the dispersion promotion component contains a styrene-butadiene rubber-based binder. 4 . The electrode production method according to claim 1 , wherein: the solid electrolyte contains a sulfide solid electrolyte; and the dispersion promotion component contains an imidazoline compound. 5 . The electrode production method according to claim 1 , wherein: the solid electrolyte contains a sulfide solid electrolyte; and the solvent contains tetralin. 6 . A solid-state battery production method comprising (e) producing a solid-state battery including the electrode according to claim 1 .
