Abstract
The invention discloses a kind of available for electrical storage device and the graphene that there is high conductivity and ion is can pass through of electric device, the graphene forms cyclic structure and internal with hole by carbon and nitrogen, and it can pass through ion, graphene is conductive, and the nitrogen concentration in graphene is 1.0at.% 35at.%.The graphene of the present invention contains nitrogen-atoms, with pore structure and permeable lithium plasma, pass through such structure, ion is easily inserted in active material or extracted from active material, the decomposition for the electrolyte being less likely to occur on the surface of active material layer, therefore the thickness for being deposited on the surface of active material layer and suppressing the skin covering of the surface of insertion and the disengaging of ion can be smaller, it is possible to increase the charge-discharge characteristic of electrical storage device.By using such graphene, electrical equipment of the lithium plasma by electrical storage device can be made so that electrical storage device has an excellent charge-discharge characteristic, high reliability and can bear long-term or reuse.
Description
Technical field
The present invention relates to can technical field of graphene, a kind of more particularly to having available for electrical storage device and electric device
High conductivity and the graphene that can pass through ion.
Background technology
Energy and environment are the two principal themes of mankind nowadays development.The mankind urgently need a kind of renewable, green cleaning
Novel energy storage device, with face of the aggravation ultracapacitors of the increasingly depleted of non-renewable resources and environmental pollution
As a kind of new type of energy storage device for having traditional capacitor and secondary cell advantage concurrently, the energy higher than traditional capacitor can be provided
Density, and the power density and cycle life more excellent compared to secondary cell, are expected to be widely used in energy conversion, boat
The field such as its system, Communication Engineering and microelectronic component it is well known that electrode material is the core component of ultracapacitor,
The quality of its performance directly determines the quality of capacitor performance.(such as capacitance is small, conduction for the inherent defect of improvement Graphene electrodes
The poor, cycle life of property is short, morphology Control is difficult).
《Graphene-polyaniline hybridized electrode material for super capacitor》The capacitor film materials conductive performance that one text is obtained
Need to improve, improve capacitance, cycle life.
The content of the invention
The object of the invention is exactly that can be used for electrical storage device and electric device there is provided one kind to make up the defect of prior art
Have high conductivity and can pass through ion graphene.
The present invention is achieved by the following technical solutions：
A kind of graphene that there is high conductivity and ion is can pass through available for electrical storage device and electric device, the graphite
Alkene forms cyclic structure and internal with hole by carbon and nitrogen, and can pass through ion, and graphene is conductive, in graphene
Nitrogen concentration is 1.0at.%-35at.%.
The hole of the graphene can pass through lithium ion.
Having porose graphene has stacked structure.
The hole formed in graphene is used as the path that ion passes through.
The lamination for having porose graphene or this graphene is used in positive electrode active material layer and negative electrode active material layer
At least one.
A kind of electrical storage device, the electrode active material of electrical storage device has used above-mentioned graphene.
It is an advantage of the invention that：The graphene of the present invention contains nitrogen-atoms, with pore structure and permeable lithium plasma,
By such structure, ion is easily inserted in active material or extracted from active material, it is not easy to occurred in active material
The decomposition of electrolyte on the surface of layer, therefore it is deposited on the surface of active material layer and suppresses the insertion and disengaging of ion
The thickness of skin covering of the surface can be smaller, therefore, it is possible to improve the charge-discharge characteristic of electrical storage device.By using such graphite
Alkene, can make the ion of lithium etc. by the electrical equipment of electrical storage device so that electrical storage device has excellent charge-discharge characteristic, high
Reliability and it can bear long-term or reuse.
