Description
Technical field
The present invention relates to field of batteries, particularly relate to a kind of zinc silver oxide cell group.
Background technology
As shown in Figure 1, the cell external series all adopting multiple structure identical forms the structure of current zinc silver oxide cell group.Each monomer as shown in Figure 2, all has a set of independently positive pole 11, negative pole 12, barrier film 13, electrolyte 14, housing 15.For reaching certain operating voltage requirement, existing zinc silver oxide cell group will, by multiple monomer series-connected, therefore need to use the accessory structures such as outside attachment lug 16, pole (positive terminal 17 and negative terminal 18), clamp nut (not shown).
The complex structure of current zinc silver oxide cell group, structural member proportion in whole zinc silver oxide cell group of zinc silver oxide cell group is very large, cause the specific power of zinc silver oxide cell group and specific capacity low, be difficult to meet installing space narrow and small, but the instructions for use that operating voltage, power are higher.In addition also adverse effect is caused to the production cost of zinc silver oxide cell group, mounting process.Further, because each monomer electric current flows through in pole process by electrode surface, the cross-sectional area of current flowing can diminish, and current density increases, and collection ear effect easily occurs, causes the reliability of zinc silver oxide cell group lower.
Summary of the invention
In view of this, the embodiment of the present invention provides a kind of zinc silver oxide cell group, by simplifying the structure of zinc silver oxide cell group, low with the specific power and specific capacity that improve zinc silver oxide cell group, and the adaptability to small space.The production cost of zinc silver oxide cell group can be reduced simultaneously, manufacture the technology difficulty of assembling.
The embodiment of the present invention provides a kind of zinc silver oxide cell group, and this zinc silver oxide cell group comprises:
Housing;
Comprise in described housing: electrolyte and multiple electric pile unit pile in series.
Further, described electric pile unit comprises: positive plate, negative plate, conductive plate and barrier film.
Further, described conductive plate is fixed on inside described housing two wall.
Further, the length of described conductive plate is greater than the length of described positive plate and is greater than the length of described negative plate; Described positive plate and described negative plate are individually fixed in the both sides of described conductive plate, and described barrier film is wrapped in the outside of described positive plate and described negative plate.
Further, there is between described multiple electric pile unit the space of the described electrolyte that circulates.
Further, the active material of described positive plate is AgO powder, and the active material of described negative plate is Zn powder, and described barrier film is chemical fibre and plant fiber paper, and described electrolyte is the potassium hydroxide solution of 30 ~ 40%.
By such scheme, this zinc silver oxide cell group comprises: the pile that housing, electrolyte and multiple electric pile unit are in series.Therefore this zinc silver oxide cell group does not need the accessory structures such as outside attachment lug, pole, clamp nut, such that the volume of battery pack is compressed largely, weight is able to a lot of degree alleviates.This zinc silver oxide cell group structure letter, specific power and the specific capacity that can improve zinc silver oxide cell group are low, and the adaptability to narrow installation space.Production cost, the fabrication technology difficulty of zinc silver oxide cell group can be reduced simultaneously.Also can increase current density, and effectively avoid collection ear effect, thus improve the reliability of zinc silver oxide cell group.

Embodiment
In order to make the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail, and obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Below in conjunction with Fig. 3 and Fig. 4, the zinc silver oxide cell group that the embodiment of the present invention provides is described in detail.
As shown in Figure 3, the structural representation of its zinc silver oxide cell group provided for the embodiment of the present invention.
This zinc silver oxide cell group comprises: the pile 24 that housing 21, electrolyte 22 and multiple electric pile unit 23 are formed.Electric pile unit 23 comprises: positive plate 25, negative plate 26, conductive plate 27 and barrier film 28.
Wherein, the active material of positive plate is AgO powder, and the active material of described negative plate is Zn powder, and barrier film is chemical fibre and plant fiber paper, and electrolyte is the potassium hydroxide solution of 30 ~ 40%
There is not independently monomer in this zinc silver oxide cell group, the both positive and negative polarity assembly (pile) of all batteries, diaphragm electrolyte are all installed concentratedly in a housing, greatly reduce existing zinc silver oxide cell group shell structure, there is not the accessory structure such as outside attachment lug, pole, clamp nut required for existing zinc silver oxide cell group, structure is simple simultaneously.
Further, the conductive plate 27 of each electric pile unit 23 is fixed on the inner side of housing 21, there is between multiple electric pile unit 23 space of circulation electrolyte 22, to avoid the phenomenon occurring that electrolyte is uneven, thus reduce the design difficulty of fluid injection or active device (the new zinc impregnation silver battery of formula of stocking), and self-balancing can be formed, the inner uniform force of pile 24 after electrolyte injects, in the course of work, internal pressure change evenly.
Further, the structure of electric pile unit 23 as shown in Figure 4, the structural representation of the electric pile unit of its zinc silver oxide cell group provided for the embodiment of the present invention.
Positive plate 25 and negative plate 26 are arranged at the both sides of conductive plate 27 respectively, and barrier film 28 is wrapped in the outside of positive plate 25 and negative plate 26, multiple electric pile unit 23 to be isolated.
In pile except the electric pile unit be connected with battery electrode and the electric pile unit be connected with battery anode, the negative plate of each electric pile unit is adjacent with the positive plate being adjacent electric pile unit.
Positive plate and the negative plate surface of each electric pile unit are all coated with barrier film, and the positive plate of adjacent two electric pile unit and negative plate are by barrier film reliable separation, can not have the part of any direct contact.
Pile 24 is formed because multiple electric pile unit 23 to be connected by conductive plate 27 by this zinc silver oxide cell group, therefore the cross-sectional area of current flowing can not change, current density can not change, and effectively can avoid collection ear effect, thus improve the reliability of zinc silver oxide cell group.
