Patent ID: 8530078

Claim:
A secondary battery,comprising: an electrode assembly including: a cathode plate, an anode plate, and a separator disposed to insulate the cathode plate from the anode plate, wherein the cathode plate, the anode plate, and the separator are wound together; a can to house the electrode assembly and having an opened end; a cap assembly including: a cap plate to seal the opened end of the can and having grooves formed therein disposed at opposing ends of the cap plate, and an electrode terminal disposed to extend through the cap assembly and to electrically connect to the anode plate, the electrode terminal being insulated from the cap plate; a protection circuit board electrically coupled to the electrode terminal and having a charging/discharging terminal on an upper surface thereof; a conducting support member connected to one of the grooves formed in the cap plate and soldered to the protection circuit board; and a combining member connected to and covering a hole formed in the middle of the protection circuit board, the combining member contacting only the surface of the protection circuit board facing the electrode terminal and being electrically connected to the electrode terminal.
