NOVELTY - A secondary battery pack comprises a printed circuit module with a printed circuit board having a protection circuit and a cathode terminal connection portion and a safety element connection portion at one end and external input and output terminal connection portion at other end. Two cases are coupled to each other through an assembly type fastening structure to cover the circuit board and safety element.    USE - A secondary battery pack for mobile devices.    ADVANTAGE - The battery pack is capable of stably coupling members mounted to the upper end of a battery cell and simplifying an assembly process and improving safety of the battery cell. It has a stable assembly structure obtained using a simplified assembly while maintaining mechanical strength and electrical insulation.    DETAILED DESCRIPTION - A secondary battery pack comprises an anode terminal (12) of a battery cell and made of a plate-shaped conductive member and connected to a protection circuit module (PCM) via a safety element; a cathode terminal (11) of the battery cell, made of a plate-shaped conductive member, and connected to the PCM; a battery cell having the anode and cathode terminals formed at its one end and provided with a thermally welded surplus portion; and a PCM comprising a printed circuit board (PCB) having a protection circuit and provided at its one side with a cathode terminal connection portion and a safety element connection portion and at the other side with an external input and output terminal connection portion. An external input and output terminal is connected to the protection circuit of the PCB via the external input and output terminal connection portion of the PCB. A first case and a second case are coupled to each other through an assembly type fastening structure to cover the PCB and the safety element. The PCM is loaded on the welded surplus portion (13) of the battery cell in a state in which the PCM is connected to the safety element and the battery cell. The cathode terminal connection portion and the safety element connection portion are made of nickel plates (15). An INDEPENDENT CLAIM is included for a method of manufacturing a secondary battery pack.    DESCRIPTION OF DRAWING(S) - The drawing is a partial perspective view of a battery cell.
