  • Patent number: 8673481
    Abstract: A housing (610, 620) for a button-type battery (?) includes a cavity with resilient conductive terminals (300, 400) therein and a door (500) opposite the terminals (300, 400). When a battery (?) is pushed inside the cavity and the door (500) is moved to its closed position, the resilient terminals (300, 400) hold the battery (?) in place, applying a force urging the battery (?) against the door (500) to better maintain electrical contact. When the door (500) is moved to its open position, the resilient terminals (300, 400) push the battery (?) at least one fifth of its diameter out of the cavity, so a user can pull out the battery (?) by hand and change the battery (?) easily.

  • Patent number: 8663838
    Abstract: A cylindrical secondary battery including a center pin having an improved structure is disclosed. The center pin is disposed into a central opening of an electrode assembly of the cylindrical secondary battery. One end portion of the center pin has a larger diameter than a central opening of an electrode assembly, and the center pin is tapered from the one end portion to another end portion of the center pin. The center pin is forcibly pushed into the central opening of the electrode assembly. Because the center pin is coupled by forced insertion with the central opening of the electrode assembly, movement of the center pin is suppressed and noise generation is prevented.
