Claim Text:
1. An all-solid battery comprising: a positive electrode comprising a binder; a negative electrode comprising a binder; and an electrolyte layer disposed between the positive electrode and the negative electrode and comprising a solid electrolyte, wherein at least one binder of the positive electrode and the negative electrode is cross-linked by a cross-linking agent, wherein the positive electrode and the negative electrode each comprises a first binder that binds to the electrolyte layer and is inactive to the solid electrolyte, wherein the first binder is cross-linked by the cross-linking agent, wherein the first binder comprises a non-polar binder, wherein the positive electrode and the negative electrode each further comprises a second binder that binds to a current collector and is more adhesive than the first binder to the current collector, wherein the second binder is optionally cross-linked by a cross-linking agent, wherein the positive electrode comprises a positive electrode layer comprising the first binder and a positive electrode active material, and an adhesive layer for binding the current collector to the positive electrode layer, wherein the adhesive layer comprises the first binder and the second binder, and wherein an amount of the first binder in the adhesive layer is about 3 weight % to about 30 weight %, and an amount of the second binder in the adhesive layer is about 2 weight % to about 20 weight % based on the total weight of the adhesive layer.
