Embodiment Construction

[0036] The invention is further illustrated by the following embodiments, and it is understood that the invention is intended to illustrate the invention.

[0037] In the present disclosure, the hybrid electrochemical energy storage device includes: a metal or metal alloy having a battery characteristics as a negative electrode; a carbon material having a capacitive energy, a transition metal oxide, a conductive polymer polymer, or the like as a positive electrode; containing a negative electrode Ion's water-based electrolyte or organic electrolyte as an electrolyte.

[0038] In one example of the invention, the negative electrode comprises a metal or alloy such as copper, lead, tin. Among them, the metal alloy can be an alloy of at least one of the doped copper, lead and tin. Among them, the morphology of the negative electrode can be a foam shape or a metal foil shape, preferably a foam, copper foil or lead foil.

[0039] In one example of the present invention, the positive ele...

Abstract

The invention relates to a hybrid electrochemical energy storage device, comprising: a metal or a metal alloy having battery characteristics is used as a negative electrode; at least one of a carbon material having capacitive performance, a transition metal oxide and a conductive high molecular polymer is used as a positive electrode; and the electrolyte is aqueous electrolyte or organic electrolyte containing metal ions corresponding to the negative electrode.

Description

Technical field [0001] The present invention relates to a hybrid electrochemical energy storage device, and more particularly to a mixed electrochemical energy storage device having a metal negative electrode, belonging to the field of preparation of an electrochemical energy storage device. Background technique [0002] With the development of the economy, energy and environmental problems are growing, and the development of portable electronic equipment and hybrid vehicles, people's demand for environmentally friendly high-power energy storage equipment is increasingly strong, and traditional energy storage devices can not meet people. Need. Alkali metals and alkaline earth metals (Li, Na, K, Mg, etc.) have been widely used as the negative electrode of the battery, with excellent energy storage characteristics and application value. However, since the alkali metal is very lively, it can only use an organic electrolyte, which is expensive, flammable and explosive, and the enviro...
