Zinc-air cell of the prior art basically all is to make full use of airborne oxygen to participate in electrochemical reaction, and factor affected by environment like this is bigger, thereby has limited the range of application of zinc-air cell.
Summary of the invention
The purpose of the utility model provides a kind of zinc-air cell that carries the oxygen bag, makes it no longer rely on airborne oxygen, has widened the range of application of zinc-air cell; The oxygen bag can be battery cell simultaneously provides continual and steady high-purity oxygen, effectively improves the current density of air electrode, thereby improves the power output of battery.
The purpose of the utility model realizes through following technical scheme:
A kind of zinc-air cell that carries the oxygen bag, said zinc-air cell comprise anodal box hat, negative pole box hat, calamine cream, air electrode, nickel screen layer, oxygen bag and oxygen bag storeroom, wherein:
Said calamine cream has a layer barrier film between said calamine cream and the said air electrode in said negative pole box hat, what be close to the other side of said air electrode is said nickel screen layer;
Said anodal box hat separates said nickel screen layer and said oxygen bag, isolates an oxygen bag storeroom simultaneously, and said oxygen bag is placed in the said oxygen bag storeroom.
The required oxygen of said zinc-air cell reaction all is stored in the oxygen bag, and said oxygen bag places said zinc-air cell inner.
Said nickel screen layer is arranged between said air electrode and the said anodal box hat.
Said anodal box hat skin is not offered air vent hole.
Technical scheme by above-mentioned the utility model provides can be found out; Said zinc-air cell comprises anodal box hat, negative pole box hat, calamine cream, air electrode, nickel screen layer, oxygen bag and oxygen bag storeroom; Wherein: said calamine cream is in said negative pole box hat; Between said calamine cream and the said air electrode a layer barrier film arranged, what be close to the other side of said air electrode is said nickel screen layer; Said anodal box hat separates said nickel screen layer and said oxygen bag, isolates an oxygen bag storeroom simultaneously, and said oxygen bag is placed in the said oxygen bag storeroom.This zinc-air cell no longer relies on airborne oxygen, has widened the range of application of zinc-air cell; The oxygen bag can be battery cell simultaneously provides continual and steady high-purity oxygen, effectively improves the current density of air electrode, thereby improves the power output of battery.
Description of drawings
In order to be illustrated more clearly in the technical scheme of the utility model embodiment; The accompanying drawing of required use is done to introduce simply in will describing embodiment below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skill in the art; Under the prerequisite of not paying creative work, can also obtain other accompanying drawings according to these accompanying drawings.
Fig. 1 is the structural representation that carries oxygen zinc covering air cell that the utility model provided.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment of the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the protection range of the utility model.
To combine accompanying drawing that the utility model embodiment is done to describe in detail further below; Be illustrated in figure 1 as the structural representation that carries oxygen zinc covering air cell that the utility model provides; Comprise anodal box hat (4), negative pole box hat (3), calamine cream (2), air electrode (5), nickel screen layer (6) and oxygen bag storeroom (1) among Fig. 1, wherein:
Successively structure does from the negative pole to the positive pole, and calamine cream (2) has a layer barrier film between calamine cream (2) and the air electrode (5) in negative pole box hat (3), and what be close to the other side of air electrode is nickel screen layer (6);
Anodal box hat (4) separates nickel screen layer (6) and oxygen bag, is separated out an oxygen bag storeroom (1) simultaneously, and the required oxygen of cell reaction all is stored in the oxygen bag, and said oxygen bag is placed in the said oxygen bag storeroom (1).
Said nickel screen layer (6) plays the effect of oxygen diffusion layer between air electrode (5) and internal positive box hat (4), in the present embodiment, the skin of said anodal box hat (4) is not offered air vent hole.
In the concrete implementation procedure, when storing battery, oxygen is stored in the oxygen bag, and positive active material and negative electrode active material are effectively isolated, and have prolonged the battery storage term of validity; When the needs activated batteries, destroy the oxygen bag with simple, effective and efficient manner, discharge the oxygen in the oxygen bag, oxygen evenly is diffused into the air electrode top layer through the nickel screen layer, participates in electrochemical reaction.
Through the structure of the described zinc-air cell of the foregoing description, widened the range of application of zinc-air cell, it is no longer relied on and airborne oxygen, can be applied in some power consumption equipments that the enclosed cell storehouse is arranged; Simultaneously, the oxygen bag can be battery cell continual and steady high-purity oxygen is provided, and effectively improves the current density of air electrode, thereby improves the power output of battery.
