ELECTROCHEMICAL CELL AND METHOD OF MANUFACTURING THEREOF

摘要

Disclosed are an electrochemical cell having excellent characteristics of impregnation with electrolytic solution and a method for manufacturing the same. The cell includes an anode, a cathode and polymer separation membrane installed between an anode and a cathode through polymer binder membrane. The polymer separation membrane is manufactured by forming polymer membrane including polyvinylidene-based polymer onto the supporting body of separation membrane. After extracting process of plasticizer, compressing process is implemented, so that plasticizer can be eliminated completely. Also, the polymer membrane is thin, so that non-uniformity of the manufacturing process is minimized. The polymer binder having a good adhesiveness is used, so that the attachment between electrode and separation membrane is practicable even at a low temperature. Additionally, since binding is a spot binding, a cell having good characteristics of impregnation with an electrolytic solution and a good performance is provided.
