Patent ID: 7169505

Claim:
A battery unit, comprising: a cathode plate having a cathode collector and a cathode active material layer coated on at least one surface of the cathode collector; a cathode lead electrically connected to the cathode collector, and having a bent U-shape; a cathode terminal electrically connected to the cathode lead; an anode plate having an anode collector and an anode active material layer coated on at least one surface of the anode collector; an anode lead electrically connected to the anode collector; an anode terminal electrically connected to the anode lead; a separator interposed between the cathode plate and the anode plate, thereby insulating the cathode plate and the anode plate from each other; a sealing tape arranged on a portion of at least one of the cathode terminal and the anode terminal that will be in contact with a sealing portion of a battery case; and an insulating member arranged on at least one of the cathode lead and the anode lead, thereby preventing a short circuit between the cathode lead and the anode plate or between the anode lead and the cathode plate, wherein the insulating member is further arranged at least between the cathode plate and the cathode terminal, or between the anode plate and the anode terminal.
