Patent ID: 7824794

Claim:
A battery, comprising: an electrode assembly including a positive electrode, a negative electrode and a separator interposed between the electrodes, the electrode assembly including a winding of the positive electrode, the negative electrode and the separator wound about a winding axis, the separator electrically insulating the positive electrode from the negative electrode; a conductive container housing the electrode assembly, the container having a first wall disposed proximate to a first side of the winding, having a second wall disposed proximate to a second side of the winding, and having a third wall facing a first end of the winding such that the winding axis is normal to the third wall, the third wall joining the first and second walls; a tab attached to a first uncoated region on the first side of the winding, the tab holding the winding in a position that is spaced apart from the first wall, the tab having a terminal that is electrically connected to the first uncoated region; a first insulator interposed between the tab and an inner surface of the first wall, the first insulator electrically insulating the tab from the inner surface of the first wall; and a cap assembly closing the container and having the terminal passing therethrough.
