Abstract
Official abstract text for this publication.
A hybrid energy storage device includes a positive pole including a supercapacitor first electrode and a battery positive electrode located in a same plane and contacts with each other, a negative pole including a supercapacitor second electrode and a battery negative electrode located in a same plane and contacts with each other, and a separator located between the positive pole and the negative pole. The supercapacitor second electrode, the battery negative electrode, the supercapacitor first electrode, the battery positive electrode, and the separator are planar structures. The supercapacitor first electrode, the supercapacitor second electrode, the battery positive electrode, the battery negative electrode, the separator and electrolyte are packaged in a shell.
