However, the energy density of supercapacitors is far less than that of lithium-ion batteries, which limits their applications.
At present, supercapacitors are used in conjunction with lithium-ion batteries, taking advantage of the high energy density of lithium-ion batteries and the high power density of supercapacitors. This method is relatively simple, but it is bulky and heavy

Abstract

The invention relates to a super capacitor battery and a manufacturing method thereof. The super capacitor battery is composed of a positive electrode, a negative electrode, a membrane, and an electrolyte. The positive electrode is connected with a positive electrode plate, and the negative electrode is connected with a negative electrode plate. At least one of the positive electrode plate and the negative electrode plate contains both a super capacitor electrode active material and a battery electrode active material. Each electrode plate is composed of a current collector and electrode active layers covering the surface of the current collector and containing electrode active material. The super capacitor electrode active material and the battery electrode active material are at least contained in different electrode active layers on the surface of the same current collector. No coverage exists or local coverage exists between the different electrode active layers. The super capacitor battery of the invention not only has high energy density and high power density, but also is simple in process and controllable in performance.

Description

technical field [0001] The invention relates to a super capacitor battery and a manufacturing method thereof. Background technique [0002] Supercapacitors have a higher power density than lithium-ion batteries and can be quickly charged and discharged. Supercapacitors are widely used and can assist batteries as the power system of new energy vehicles, and cooperate with batteries as power systems in the field of wireless transmission. They can be used alone for solar or Energy storage system for wind power generation, or for military and other fields. However, the energy density of supercapacitors is far lower than that of lithium-ion batteries, which limits their applications. At present, supercapacitors are used in conjunction with lithium-ion batteries, taking advantage of the high energy density of lithium-ion batteries and the high power density of supercapacitors. This method is relatively simple, but it is bulky and heavy. Contents of the invention [0003] The p...
