More Information
Summary:The invention discloses a hybrid energy storage device which comprises a porous carbon anode, a titanium oxide cathode, a lithium-containing electrolyte solution and a diaphragm, wherein the diaphragm comprises a polyimide fiber membrane and a filler attached to a single surface of the polyimide fiber membrane. By the hybrid energy storage device, a supercapacitor and dual power supplies of a battery can be externally combined, internal fusion is achieved through porous carbon, titanium oxide, the high-temperature resistant diaphragm and the like, and the hybrid energy storage device has the hybrid energy storage characteristics of dual-electrode layer of the supercapacitor and intercalated/deintercalated lithium of a lithium ion battery.
