ELECTRODE ASSEMBLY, AND RECHARGEABLE BATTERY

摘要

An electrode assembly includes an electrode stack that includes a positive electrode, a negative electrode, and a separator, the separator being interposed between the positive electrode and the negative electrode, a positive electrode tab projecting from an edge of the electrode stack, and a negative electrode tab projecting from an edge of the electrode stack. The electrode stack may have a height direction, a width direction, and a thickness direction, the thickness direction being substantially perpendicular to a plane that includes the height and width directions, the electrode stack having a first thickness in the thickness direction at a first location corresponding to at least one of the positive and negative electrode tabs, the electrode stack having a second thickness in the thickness direction at a second location peripheral to the first location, the first thickness being greater than the second thickness.
