Description
Technical field
The utility model belongs to the battery technology field, is specifically related to a kind of power type zinc-air cell.
Background technology
Zinc and air cell is a kind of of metal-air battery, belongs to the semi-fuel cell category.It has advantages such as specific energy height, abundant raw materials, price are not high, pollution-free, is considered to the competitive candidate of electric vehicle battery.Zinc-air cell develops so far, and the obstacle that large-scale commercial applications is used mainly is not satisfactorily resolve charging technique.Although the secondary zinc-air cell has been carried out a large amount of research and development, the commercial application of still being unrealized.
At present, the charging difficult problem of reply zinc-air cell, adopt following several technology: (1) machinery is changed zinc electrode, promptly after battery discharges fully, the zinc electrode of using in the battery is taken out, and changes to new zinc electrode, perhaps entire cell is fully more changed.The zinc oxide mixture that changes recycles in electrolysis tank, and electrolytic zinc can be made zinc electrode more again through simple process.Used time of the whole process of this " charging " mode is short, but electrode and converting mechanism complexity comparatively more; (2) circulation slurry zinc negative pole.
Present existing battery structure also comes with some shortcomings, and it is comparatively complicated to change service system as zinc electrode, the solution leakage of battery, climbs Lou or overflows etc.These problems have seriously influenced applying of zinc and air cell.
The utility model content
The purpose of this utility model provides a kind of power type zinc-air cell, and it helps being convenient for changing of negative pole, and its battery bottom port sealing is good simultaneously, can prevent effectively that solution from leaking from the bottom.
The technical solution adopted in the utility model is as follows:
A kind of power type zinc-air cell comprises shell, the built-in a plurality of air electrode assemblies of described shell, negative pole assembly; The air electrode assembly includes the plastic cylinder that has air-vent from the tubular diaphragm layer, air electrode cylinder, the sidewall that are equipped with successively outside to inside; The nozzle of air electrode tube connects anodal current collection flat board; The negative pole assembly is calamine cream and the collector body that is inserted in the calamine cream the inside, and this calamine cream is filled between membrane layer and the shell; Described outer casing bottom central authorities are provided with air vent hole, around the shell some calamine cream hand-holes are arranged, and described plastic cylinder links to each other with the air vent hole of described outer casing bottom, and air enters and air-vent by plastic cylinder is diffused into air electrode tube surface from air vent hole.
The utility model is also further by the following technical solutions:
Described outer casing bottom has a plurality of circular slot that is complementary with described air electrode assembly bottom shape, and described air electrode assembly bottom is plugged on the described outer casing bottom by described circular slot.
Described air electrode assembly bottom and described circular slot seal by seal washer.
The cross section of described battery case is square, rectangle or cylindrical.
The utility model and flat air electrode compare, and it is less that the cylindrical shape air electrode bears mechanical force, more easily avoid changing the negative pole process and are damaged, and negative zinc cream is easy to change; Help to improve the utilance of calamine cream simultaneously; In addition, it seals air electrode assembly bottom and the circular slot of outer casing bottom joint by seal washer, can prevent effectively that the solution of inner new peak from leaking from the bottom.
