Abstract
A water-soluble binder composition including a first polymer having one or more hydroxyl groups in its repeating unit, and a polybasic acid compound. The binder composition is for an electrode and is environmentally friendly, has improved cycle life characteristics, and has improved adhesion strength of an active material and improved adhesion strength of the active material to a current collector. An electrode including the binder composition and a secondary battery including the electrode, are also provided.
