Paillon is covered in the anode plate and on the contact site of the negative plates, the anode plate and the conductive part of the negative plates are distinguished
It is at least partly exposed to outside the aluminium foil and is not covered by it, wherein, aluminium foil one side directed downwardly is with the anode plate with being somebody's turn to do
The second face contact of negative plates, and aluminium foil one side surface directed downwardly is furnished with a plastic layer.
(3) hot pressing：With a hot-press arrangement from the top of aluminium foil pressurized, heated down, make the plastic layer and the anode pole
Plate and the second face of the negative plates are bonded to each other.
Further, the anode plate and the conductive part of the negative plates are respectively strip.
Further, the anode plate and the negative plates at least within one with the galvanic corrosion foil of metal is made and
Directly form the rough surface.
Further, the second face of the anode plate and the negative plates one at least within is scraped with external force friction
Slightly to form the rough surface.
Further, the second face of the anode plate and the negative plates one at least within is coated with a coating
To form a graininess thin layer.
Further, the anode plate is aluminium into the negative plates are made of copper metal.
Further, at step (2), it is enterprising that the anode plate with the negative plates is placed in a silica gel pad
Row operation.
Further, at step (3), with 1 to 6 kilogram/square centimeter of pressure, the temperature in Celsius 100 to 200 degree
Degree carries out heat pressing operation.
Further, the plastic layer is polypropylene.
Beneficial effects of the present invention are：
A kind of electrode adhesion method of flexible battery provided by the invention, can be with simplest process by anode, cathode
Pole plate is individually fixed on aluminium foil, and can be combined closely after rough surface and plastic layer hot pressing, promotes fixed effect, whole process
It is not necessary to bind pole plate each other with aluminium foil using sticker, cell thickness can be reduced, and simplify manufacturing process, make finished battery more
It is thin lighter.

Specific embodiment
The possible implementation form of the present invention is only illustrated with embodiment below, however is not to limit claimed by the present invention
Scope, conjunction first chat it is bright.
It please refers to Fig.1 to Fig. 6, the present invention provides a kind of electrode adhesion method of flexible battery, comprises the steps of：
(1) standby an anode plate 10 and a negative plates 20：The anode plate 10 is respectively a gold medal with the negative plates 20
Belong to thin slice (in the present embodiment, which is aluminium into the negative plates are made of copper metal) and opposite end
Respectively comprising a conductive part 12,22 and a contact site 11,21, the contact site 11,21 have one first opposite face 111,211 and
One second face 112,212, first face 111,211 are furnished with activator, which has a rough surface, the conduction
Portion 12,22 is strip, about the rough surface, the anode plate and the negative plates at least within one with the galvanic corrosion foil of metal
Be made and directly form the rough surface, also or with external force friction scrape slightly to form the rough surface, can also be coated with a coating with
Form a graininess thin layer.
(2) aluminium foil 40 is covered：By the anode plate 10 and 20 arranged adjacent of negative plates and the second face 112 made,
212 are placed in upward on a silica gel pad 30, and an aluminium foil 40 is covered in the contact with the negative plates 20 of anode plate 10
In portion 11,21, the anode plate 10 and the conductive part 12,22 of the negative plates 20 are at least partly exposed to the aluminium foil 40 respectively
