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.
