Abstract
The invention provides a kind of graphene conductive paper and paper battery and its application.A kind of graphene conductive paper, mainly by nano-carbon material, paper pulp and auxiliary agent with 10 50%：40 75%：8 18% mass percent is made；Described nano-carbon material includes at least Graphene, and described auxiliary agent is one or more of modified starch, PAMA, polyvinyl alcohol, carboxymethyl cellulose.The present invention is applied to paper battery field to be had the advantages that to improve specific capacity, stable cell performance, improves battery life.
Description
Technical field
The present invention relates to conductive material field, in particular to a kind of graphene conductive paper
And paper battery and its application.
Background technology
The problems such as weight of battery, not bent, capacity, life-span, hampers electronics always and produces
The further lighting of product.Paper battery contributes to mitigating the weight of electronic product, extends product
Life-span, and give battery certain pliability, play and mutually push away with light flexible electronic product
Dynamic effect.
Using ripe paper technology, conductible paper is used as current collector and electrode, provides
A kind of thinking of low cost, lightweight and efficient energy reservess.At present the whole world only the U.S.,
There is certain developmental achievement in several country such as Israel, Finland, Sweden in this area.Paper electricity
Pond is mainly with fibrous paper as carrier, is coated with the ink that nano material is made or prints,
Constitute battery or ultracapacitor.This paper battery can be cut out, bend, environmentally friendly
And cost is not high.Its application is related to RF Reader (RFID), electronic tag, intelligence
Card etc., potential application field is then related to many electronic products such as mobile phone, laptop computer.
The nano-carbon materials such as conduction active-carbon, CNT, Graphene are excellent due to having
Electric conductivity and stable physical and chemical performance, receive more and more attention in paper battery research,
Especially Graphene.Such as CN103966907A, CN102619128B,
The patent applications such as CN102169999B all have studied nano-carbon material in paper battery or paper electrode
In application, these technical schemes are all simply to be blended in nano-carbon material with paper pulp
Make paper electrode together, or be additionally added electrode active material, do not consider nano-sized carbon
The impact to paper battery electric conductivity for the mixed effect of material and paper pulp, leads to the conduction of electrode
Performance improve inconspicuous it is impossible to give full play to the superiority of nano-carbon material.
In view of this, the special proposition present invention.
Content of the invention
The first object of the present invention is to provide a kind of graphene conductive paper, described Graphene
Conductive paper both can be as the positive pole of paper battery it is also possible to negative pole as paper battery, application
In paper battery field, there is raising specific capacity, stable cell performance, raising battery life etc. excellent
Point.
The second object of the present invention is to provide a kind of graphene paper battery, described Graphene
Paper battery has the advantages that battery capacity height, stable performance, life-span length.
The third object of the present invention there are provided the application of graphene conductive paper, and this application is non-
Often extensive, including the power supply for making wearable device or dress ornament, or lead for making
Power supply of electric facial film etc., the present invention is applied to be not intended to limit.
In order to realize above-mentioned first purpose of the present invention, spy employs the following technical solutions：
A kind of graphene conductive paper, mainly by nano-carbon material, paper pulp and auxiliary agent with 10-50%：
40-75%：The mass percent of 8-18% is made；Described nano-carbon material includes at least stone
Black alkene, described auxiliary agent is modified starch, PAMA, polyvinyl alcohol, carboxylic first
One or more of base cellulose.
Compared with prior art, the above-mentioned graphene conductive paper of the present invention mainly chemically forms
On optimize the interpolation type of auxiliary agent and itself and nano-carbon material, the proportioning of paper pulp, thus
