Official abstract text for this publication.
The present disclosure relates to a binder solution for all-solid-state batteries. The binder solution includes a polymer binder, a first solvent, and an ion-conductive additive, wherein the ion-conductive additive includes lithium salt and a second solvent, which is different from the first solvent.
Opening claim text (preview).
What is claimed is: 1. A method of manufacturing an all-solid-state battery, the method comprising: preparing an ion-conductive additive comprising lithium salt and a second solvent; mixing a polymer binder, a first solvent, and the ion-conductive additive to manufacture a binder solution; mixing the binder solution, an electrode active material, a conductive material, and a solid electrolyte to manufacture an electrode slurry; and applying the electrode slurry to a substrate and drying the electrode slurry at a temperature of 60° C. to 120° C. to form an electrode, wherein the first solvent has a dielectric constant (ε) of 1 to 10 and a Gutmann donor number (DN) of 0 to 10, wherein a molar ratio of the lithium salt to the second solvent is 1 to 1.2, wherein the second solvent is selected from a group consisting of triethylene glycol dimethyl ether, 12-Crown-4, 15-Crown-5, 18-Crown-6, or mixtures thereof, and wherein an absolute value (|Ag|) of a difference in dielectric constant between the first solvent and the second solvent ranges from 0 to 5. 2. The method according to claim 1 , wherein: the polymer binder is selected from a group consisting of nitrile-butadiene rubber (NBR), butadiene rubber (BR), polystyrene (PS), styrene butadiene rubber (SBR), polymethyl methacrylate (PMMA), polyethylene oxide (PEO), or mixtures thereof. 3. The method according to claim 1 , wherein: the first solvent is selected from a group consisting of toluene, hexane, dibromomethane, dichloromethane, chloroform, butyl butyrate, hexyl butyrate, or mixtures thereof. 4. The method according to claim 1 , wherein: the lithium salt is selected from a group consisting of lithium hexafluorophosphate (LiPF 6 ), lithium bis(fluorosulfonyl)imide (LiFSI), lithium bis(trifluoromethanesulfonyl)imide (LiTFSI), lithium bis(pentafluoroethanesulfonyl)imide (LiBETI), or mixtures thereof.
