Abstract
The utility model relates to a flexible film battery capable of freely bending, and the thickness of the battery is 0.6-1.0MM. The utility model is formed by the process that two electric conductive films are made by respectively coating electric conductive paint on two insulating films; an anode film of the flexible film battery is made by brushing anode slurry on one of the two electric conductive films; a cathode film of the flexible film battery is made by brushing cathode slurry on the other electric conductive film; then, an isolating layer brushed with wet electrolytical special filter paper is molded, pressed and sealed. The utility model not only overcomes the defects that the thickness of general dry batteries and button batteries are thick and can be not bent, and meanwhile, the utility model has the advantages of environmental protection for selected materials and without hazardous substances for human bodies. The utility model is suitable for various aspects of communication, counters, electronic watches, toys, etc.
Description
The utility model relates to a kind of flexible thin-film battery that chemical energy is changed into electric energy.It is to coat electrically-conducting paint respectively to make two conducting films on two insulation films.Brush anode sizing agent on the conducting film therein then, make anode.Brush cathode size again on another conducting film and make battery cathode, middle is that the separator mold pressing forms to be brushed with wet electrolytical special filter paper.Its thickness is 0.6～1.0mm, can be crooked arbitrarily.It is a kind of disposable flexible thin-film battery.
Technical background
Develop rapidly along with miniature precision electronic products such as electronic computer, phone, toy, electronic watch, temperature surveys, occurred the demand of small-sized flexible thin-film battery increasingly, pressed for a kind of reliable flexible thin-film battery as the power supply of these devices.
Present known battery is mainly done shell with metals such as zinc, Gang Huo Aluminum, and its thickness is thicker, and can not free bend while complex manufacturing.Needs along with the more and more incompatible development of the big inflexible battery of the old-fashioned volume of the diversified develop rapidly of miniaturization of electronic products.
Summary of the invention
Thicker in order to overcome its thickness of existing battery, and deficiency that can not free bend, the utility model provides a kind of flexible thin-film battery, and this flexible thin-film battery not only thickness is 0.6～1.0mm but also can free bend.
The technical scheme that its technical problem that solves the utility model adopts is: open type structure in the middle of adopting three layers being on two insulation films of material with insulation films such as PP, PVC or PE, is coated with carbonaceous conductive coating respectively and makes two conducting films.Brush the manganese slurry on the conducting film therein then and make anode, on another conducting film, brush the zinc slurry and make battery cathode.The centre is made wet dielectric substrate with the electrolyte solution brushing and is formed for the separator mold pressing on the special filter paper of the good porous material of moisture absorption.
The beneficial effects of the utility model are, utilize the thin thickness of PP, PVC or PE insulation film and bendability characteristics to do shell and adopt simple production technology to make thin thickness, but and the flexible thin-film battery of free bend.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is flexible thin-film battery basic principle figure.
The vertical section basic structure perspective view of first embodiment of Fig. 2 flexible thin-film battery.
Fig. 3 combination flexible thin-film battery vertical section basic structure perspective view that to be second embodiment of flexible thin-film battery formed by two battery tandem compounds of Fig. 2.
1. dielectric films among the figure, 2. insoluble negative pole 3. wet dielectric substrate 4. insoluble positive poles
Flexible thin-film battery constitutes by five layers among Fig. 1.Ground floor is insulation film (1), makees battery case.The second layer is insoluble negative pole (2), and the 3rd layer is wet dielectric substrate (3), and the 4th layer is insoluble positive pole (4), and layer 5 is similarly insulation film (1). oxidation reaction takes place in the negative pole of discharge (2), and reduction reaction takes place anodal (4).Wet dielectric substrate (3) all keeps moistening easy hygroscopic material of battery and institutes such as water-soluble polymer that obtains required viscosity and trace mineral supplement to form by Zai Ren He Time time.The solubility electroactive material carries out selection according to the difference of the positive and negative electrode of manufacturing.Be applicable to that electroactive material of the present invention has zinc chloride, zinc bromide etc.
Water-soluble polymer is used as binding agent, and electrode layer (2) and (4) are bonded on the wet dielectric substrate (3).
Insoluble negative pole (2) is by zinc powder and the synthetic zinc slurry of polyester, and brush is made on carbonaceous conductive coating.Insoluble positive pole is made on carbonaceous conductive coating by the manganese slurry brush that oxidation manganese powder and polyester synthesize.
With above-mentioned five layers combine flexible thin-film battery.
The flexible thin-film battery of above-mentioned as seen from Figure 1 five layers of combination can make very thin, but and to have its thickness of flexibility free bend only be 0.6～1.0mm..Example one
In first embodiment of Fig. 2 flexible thin-film battery, in 100mL distilled water or ionized water, add 10g polymer and trace mineral supplement, be mixed with electrolyte solution, this electrolyte solution brushing is made wet dielectric substrate (3) at the special filter paper of the good porous material of moisture absorption. be that dielectric film (1) brushes conductive carbon paste respectively and makes the Two conducting film with the PP film of two fast 47 * 47mm again.
With an amount of zinc powder and the synthetic zinc slurry of polymer, brush makes the insoluble negative pole of hull cell (2) on an above-mentioned fast conducting film that has prepared. again with an amount of oxidation manganese powder and the synthetic manganese slurry of polymer, brush makes the insoluble positive pole of hull cell (4) on above-mentioned another fast conducting film that has prepared. and be separator with wet dielectric substrate (3) then, above-mentioned each layer mold pressing made flexible thin-film battery.
The external load testing magnitude of voltage of battery is reduced to the electric current that 1.2V can keep 13uA/cm in continuous 5 days from 1.6V at ambient temperature.Example two
In second embodiment of Fig. 3 flexible thin-film battery,, contact mutually by conductive tape or printing conductive film (5) by two groups of flexible thin-film batteries (6) that above-mentioned first embodiment method makes.An external load testing magnitude of voltage is reduced to 2.4V from 3.1V at ambient temperature, can keep the electric current of 13uA/cm in continuous 5 days.The method can be formed any needed parallel connection or the series direct current battery pack is used for the user.Example three
In the 3rd embodiment, a flexible thin-film battery that makes by above-mentioned first embodiment method.Not external any load, at ambient temperature, battery can keep at least one year above (1.6V～1.2V) continuously.
