Abstract
The utility model discloses an artificial graphite negative strip of a lithium battery, and relates to the field of the lithium battery. The artificial graphite negative strip of the lithium battery comprises a copper foil layer, artificial graphite layers and conductive adhesive layers, wherein the conductive adhesive layers are coated on the front surface and the back surface of a copper foil; and the artificial graphite layers are coated on the conductive adhesive layers respectively. Compared with the prior art, the battery manufactured by the artificial graphite negative strip of the lithium battery has high cycle index and superior and stable electrical property.
Description
Technical field
The utility model relates to a kind of lithium battery field, particularly a kind of lithium battery artificial plumbago negative pole band.
Background technology
Existing cathode of lithium battery generally adopts carbon-point, but the battery that such negative pole is made can not carry out repeatedly cycle charge-discharge, again because the carbon-point catchment effect is bad, so the battery electrical property instability of making, electrical property is also poor, can not satisfy the development of lithium battery.
Summary of the invention
The purpose of this utility model just is to provide a kind of lithium battery artificial plumbago negative pole band, and the battery cycle-index that this lithium battery artificial plumbago negative pole band is made is many, good electrical property and stable.
The technical solution of the utility model is: a kind of lithium battery artificial plumbago negative pole band, this lithium battery artificial plumbago negative pole band comprises Copper Foil lamella, Delanium layer and conduction tack coat, described conduction tack coat is coated on the positive and negative two sides of described Copper Foil lamella, and described Delanium layer is coated in respectively on the described conduction tack coat.
As preferably, described conduction tack coat is conduction PVDF layer.
A kind of lithium battery, this lithium battery adopt above-mentioned described lithium battery artificial plumbago negative pole band.
Compared with prior art, the beneficial effects of the utility model are: will conduct electricity tack coat and be coated on the positive and negative two sides of Copper Foil lamella because adopt, the Delanium layer is coated on the conduction tack coat, wherein, aluminium foil is easy to lithium ion is concentrated the output input, and the Delanium layer is easy to stable lithium ion and the output lithium ion of receiving, the conduction tack coat with Delanium layer secure bond on copper foil, therefore the lithium battery cycle-index of this lithium battery artificial plumbago negative pole band making is many, good electrical property and stable.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Lithium battery artificial plumbago negative pole band as shown in Figure 1, this lithium battery artificial plumbago negative pole band comprise Copper Foil lamella 1, Delanium layer 21, Delanium layer 22, conduction tack coat 31 and conduction tack coat 32.Conduction tack coat 31 and conduction tack coat 32 make Delanium layer 21, Delanium layer 22 secure bond on Copper Foil lamella 1, do not reduce conductivity simultaneously.
Conduction tack coat 31 is coated in described Copper Foil lamella 1 front, conduction tack coat 32 is coated on the copper foil reverse side, and Delanium layer 21 is coated on the conduction tack coat 31, Delanium layer 22 is coated on the conduction tack coat 32.
Conduction tack coat 31, conduction tack coat 32 are conduction PVDF layer.Conduction PVDF is doped with conducting particles in PVDF.
Delanium layer 21, Delanium layer 22 adopt the Qingdao Delanium.
The lithium battery that adopts lithium battery artificial plumbago negative pole band as shown in Figure 1 to make, its cycle-index is many, and good electrical property and stable can be widely used in each electron trade.
