POROUS SEPARATOR AND METHOD OF MANUFACTURING THE SAME

摘要

Disclosed are a porous separator on which a binder material is dispersed to facilitate an advantageous attachment with an electrode and a method of manufacturing the same. First, a solution containing a polymer binder is coated ontoa porous polymer layer. Then, a solvent is removed to manufacture the separator.The polymer binder material bestows a good adhesive strength between the electrode and the separator. In addition, an electrolytic solution can be easily impregnated into the electrode and the separator through a space where the bindercomponent is not present. An electro chemical cell manufactured by employing the separator has a high capacity and a stable cyclelife characteristic.
