Binder For All Solid State Battery, Cathode For All Solid State Battery, And All Solid State Battery Comprising Same

Abstract: The present invention relates to: a binder for an all-solid-state battery, comprising a first polymer in which a chain containing a first hydrogen bondable functional group is grafted as a side chain onto the main chain of a conjugated diene polymer, and a second polymer in which a chain containing a second hydrogen bondable functional group is grafted as a side chain onto the main chain of the conjugated diene polymer, wherein the first hydrogen bondable functional group of the first polymer forms a hydrogen bond together with the second hydrogen bondable functional group of the second polymer; a cathode for an all-solid-state battery, comprising the binder for an all-solid-state battery cathode, a conducting material, a cathode active material, and a solid electrolyte; and an all-solid-state battery comprising a cathode, an anode, and a solid electrolyte layer disposed between the cathode and the anode, wherein the cathode includes the cathode for an all-solid-state battery.
