PURPOSE: An aqueous active material composition is provided to have excellent dispersity, excellent absorption, and to provide an electrode with excellent adhesion and low resistance. CONSTITUTION: An aqueous active material composition comprises an active material, a binder, and a water-soluble cellulose mixture. The water-soluble cellulose mixture comprises a first cellulose compound with a substitution degree of 0.5-0.9 and a second cellulose compound with a substitution degree of 0.5-0.9. The first cellulose compound and the second cellulose are selected from carboxymethyl cellulose, methyl cellulose, hydroxylethyl cellulose, hydroxylpropyl cellulose, and a combination thereof. |
