20090239142 | ELECTROCHEMICAL DEVICE - This electrochemical device includes a first frame, a second frame, and a laminated electrochemical element having a housing encasing an element. Outer edges of the housing are sandwiched between the first frame and the second frame. Hook members are provided on one of the first frame and the second frame, and indentations engaging the hook members are provided on the other one of the frames, thereby fixing the relative positional relationship between the first frame and the second frame. | 09-24-2009 |
20090263712 | FILM-PACKAGED ELECTRIC DEVICE - To provide a film-packaged battery | 10-22-2009 |
20090263713 | BATTERY COVER ASSEMBLY - A battery cover assembly includes a back cover, a battery cover and at least one elastic device. The back cover includes a battery chamber recessed there-into and an separation-preventing portion protruding therefrom. The battery cover is slidably mounted on the battery chamber of the back cover and includes an anti-detaching portion protruding therefrom. The anti-detaching portion is configured for being blocked by the separation-preventing portion to avoid the battery cover being released from the back cover when the battery cover is slid relative to the back cover. The elastic device has two opposite ends secured to the back cover and the battery cover respectively. The elastic device is configured for providing an elastic force to open the battery cover relative to the back cover. | 10-22-2009 |
