Abstract
An electrode including a binder comprising a waterborne polyurethane polymer compound and an electrode active material is provided. The waterborne polyurethane polymer compound improves the binding properties of the electrode. In addition, the polymer compound disperses well in water and is hardened through a crosslinking reaction to increase elastic force, thereby enabling adjustment of elastic and binding forces. As a result, a battery including the polymer compound has excellent recovery and charge/discharge properties.
