Abstract: A hybrid energy storage device includes a positive pole formed by stacking a supercapacitor first electrode and a battery positive electrode, a negative pole formed by stacking a supercapacitor second electrode and a battery negative electrode, 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.

Abstract: The invention relates to a rechargeable battery includes a first electrode, a second electrode, a separator, and electrolyte. The first electrode includes a first supercapacitor electrode, a first battery electrode, a first current collector, and a first connector. The first battery electrode is sandwiched between the first supercapacitor electrode and the first current collector. The first supercapacitor electrode and the first current collector are electrically connected via the first connector.

Abstract: A method for making a carbon nanotube composite structure includes suspending a carbon nanotube layer in a reactor. A polymer monomer solution and an oxidant solution are gasified by a pressure to form polymer monomer solution gas and oxidant solution gas. The polymer monomer solution gas is polymerized and chemically bonded to the carbon nanotube layer in initiation of the oxidant solution gas.
