Abstract: Provided is a cellulose derivative composition for an all-solid-state secondary battery binder including a compound represented by Formula 1 below according to the inventive concept. In Formula 1, R1, R1′, R2, R2′, R3, and R3′ are each independently any one among a carboxymethyl group, a sulfur substituent, or a phosphorus substituent, in which a monovalent metal is substituted or hydrogen, wherein R1, R2, and R3 is —CH2COOX, , SO3X, —PO3X or —PO3X2 where X may be any one among sodium (Na), potassium (K), rubidium (Rb), or cesium (Cs). R1′, R2′, and R3′ is —CH2COOY, —SO3Y, —PO3Y or —PO3Y2 where Y may be lithium (Li).
