Abstract: A lithium-ion battery including a positive electrode, a negative electrode, a separator disposed between the positive electrode and the negative electrode, and an electrolyte. The positive electrode includes a positive current collector and a positive electrode active material layer containing lithium cobalt oxide formed on the positive current collector. The positive electrode active material layer is provided with a first recess accommodating a positive lead coupled with the positive current collector and disposed on a surface of the positive current collector facing a center of the battery. The negative electrode includes a negative current collector and a negative electrode active material layer containing graphite or silicon formed on the negative current collector. The negative electrode active material layer is provided with a second recess accommodating a negative lead coupled with the negative current collector and disposed on a surface of the negative current collector facing away from the center of the battery.

Abstract: A secondary battery, including an electrode assembly and a housing accommodating the electrode assembly. The electrode assembly includes a first electrode plate, a second electrode plate, and a separator disposed there between. The first electrode plate and the second electrode plate are wound to form the electrode assembly. A tab is disposed in the first electrode plate and protrudes from the housing; and an adhesive layer is disposed in the tab. The adhesive layer includes a first portion sandwiched between a package area of the housing and a second portion extending from the first portion along a length direction of the tab. In a width direction of the tab, the first portion has a width greater than that of the second portion. In the length direction of the tab, the second portion protrudes into a space enclosed by an innermost layer of the separator.
