CELL PART AND SECONDARY CELL USING THE SAME

摘要

PURPOSE: A cell part and a secondary cell using the same are provided to prevent the corrosion or the short due to the contact between electrode plates and between an electrode plate and a case, to improve stability and confidence, and to prevent the separation of a tab. CONSTITUTION: The cell part comprises an anode plate(51) having an anode collector(51a) and anode sheets(51b,51c) selectively formed on the both sides of the anode collector(51a); an anode tab(54) electrically connected with the anode collector(51a) and having a protective tape(56) at the part protruded from the anode collector(51a); a cathode plate(52) having a cathode collector(52a) and cathode sheets(51b,51c) selectively formed on the both sides of the cathode collector(52a); a cathode tab(55) electrically connected with the cathode collector(52a) and having a protective tape(56) at the part protruded from the cathode collector(52a); a separator(53) inserted between the anode plate(51) and cathode plate(52); and multiple short preventing means which is formed on the parts of the anode and cathode collectors not having anode and cathode sheets and has a width larger than that of the anode and cathode collectors.
