Abstract
A secondary battery capable of being formed to be relatively small by reducing the sizes of internal devices and compactly locating the internal devices. Accordingly, the volume of the secondary battery is reduced and the capacity thereof is maintained, thereby increasing the capacity density of the secondary battery. In one embodiment, the secondary battery includes a bare cell having a cap plate and a protection circuit module on the bare cell and including a printed circuit board surface-contacting the cap plate.
Claims28
A secondary battery comprising:
- a bare cell comprising a cap plate;
- and
- a protection circuit module on the bare cell and comprising a printed circuit board surface-contacting the cap plate.
A secondary battery comprising:
- a bare cell;
- and
- a protection circuit module on the bare cell and comprising a lead plate at a short edge portion of the protection circuit module,
- the lead plate on a top surface of the bare cell for clamping the protection circuit module to the bare cell.
A method of forming a secondary battery, the method comprising:
- forming a protection circuit module on a bare cell from a printed circuit board having a first side contacting the bare cell without any empty space therebetween;
- and
- surface mounting a charge/discharge terminal section on a second side of the printed circuit board for electrically connecting the bare cell to an external device.
