Description
Technical field
The present invention relates to lithium battery, more particularly, to a kind of miniature thin-film lithium electricity of use graphene film as negative pole
Pond.
Background technology
Now, developing rapidly with MEMS (MEMS), external power supply can not meet growing miniature
Change, integrated demand.Miniature thin-film battery due to its size flexibly, safety and the advantages of high-energy-density, taken off in micro- energy
Grain husk and go out.Wherein, the research of current lithium battery and it is most widely used, therefore miniature thin-film lithium battery turns into actual microdevice
The first choice of energy supply.In addition, the solid electrolyte that it is used solves the safety problem of common lithium battery, have in future very big
Development prospect.
Miniature thin-film lithium battery, is generally made up of collector, negative film, electrolytic thin-membrane and anode thin film, and battery
Geometry also have diversified forms, common structure is as described in United States Patent (USP) US 5338625.And it is prepared mainly by various
Film deposition techniques, including radio-frequency magnetron sputter method, pulsed laser deposition, vacuum thermal evaporation, chemical vapour deposition technique etc., knot
Photoetching, stripping or masked-deposition of micro fabrication etc. is closed to realize.
But existing " graphene lithium battery ", it is most of simply using graphene as both positive and negative polarity or additive agent electrolyte,
Or it is used as positive pole or negative as the part enhancing electric conductivity and thermal diffusivity of collector, rather than using and only with graphene
Real " graphene battery " of pole, the below definition in this, as " graphene battery " is stated.Such as Chinese patent
Graphene polymer lithium battery disclosed in CN104538582, using graphene leading as graphite electrolyte and copper foil current collector
Electric layer, improves conductive capability and energy density, but graphene is not active material in itself, do not provide comprising positive pole yet and
The completed cell structure of collector.Even with lithium battery of the graphene as active material, complete graphite is not also used
Alkene film is as electrode, the graphene lithium battery as disclosed in Chinese patent CN105529469, with including graphene, polymer with
And catalyst etc. is as negative electrode, using lithium metal as anode, main description uses 3-dimensional metal substrate and polymer catalyzing side
Method directly prepares three-dimensional grapheme gel as negative electrode, and individual layer or few layer graphene film and solid electrolyte is not used, together
When graphene as cathode material, for the lithium battery using traditional positive pole of Chinese patent, output voltage is smaller, space
Utilization rate is low, and complex process, cost is larger, and use has been chemically incorporated into nonreactive polymers impurity, and be difficult to it is micro-
The system integration.
So far the extensive preparation of " graphene lithium battery " is also realized without simple, complete micro-processing method.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a kind of use graphene film and is used as the miniature of negative pole
Film lithium cell.
The present invention is sequentially provided with copper foil substrate, graphene negative electrode film, solid electrolyte film, cathode film and positive pole from bottom to up
Collector；The graphene negative electrode film is the graphene film being grown directly upon using chemical vapour deposition technique on copper foil substrate；
The solid electrolyte film, cathode film and plus plate current-collecting body are using photoetching, deposition and peel off, or directly mask deposition realizes figure
Shape.
Sample is pasted onto in hard substrates by the photoetching, deposition and stripping using double faced adhesive tape to be operated.
The graphene negative electrode film is individual layer or few layer graphene；The thickness of the solid electrolyte film can be 0.1~1 μ
m；The thickness of the cathode film can be 0.1~1 μm.
The hard substrates can be using silicon chip, glass or stainless steel lining bottom etc.
The present invention is using the individual layer or few layer graphene two-dimensional film of chemical vapour deposition technique preparation directly as lithium battery
Negative material, improve the electrical conductivity, specific surface area and stock utilization of negative material.The present invention only with one piece of mask or
Masked-deposition, is fixed using double faced adhesive tape, is removed when peeling off together with unnecessary photoresist, and process is easy to be high
Effect, can be prepared all solid state and film-type real " graphene lithium battery ".
Compared with prior art, the beneficial effects of the invention are as follows：
1st, it is used as negative material using and only with individual layer or few layer graphene film.
2nd, the high conductivity and specific surface area of individual layer or few layer graphene improve miniature thin-film lithium battery energy density and
High rate performance.
3rd, prepared by technique and battery structure is simple, only needs one piece of mask plate, it is easy to accomplish large-scale production.
4th, prepared by technique and battery structure is compatible with microelectronic technique, easily realizes integrated with microdevice.
