Description
Technical field
The utility model is related to field of batteries, in particular to a kind of short cylindrical zinc-air battery.
Background technology
Zinc-air battery, also known as zinc-oxygen battery have, cheap, discharge voltage stabilization, to environment friend higher than energy
The features such as good, is widely used in various Portable power sources.Make its working principle is that absorbing oxygen in air using carbon-coating
For the zinc material in positive active material, with battery electric energy is discharged to constitute oxidation-reduction pair as reduzate.
Most of zinc-air battery currently on the market, the hard such as positive and negative electrode shell generally use metal-back or plastic housing
Material is made, and by pressing, bonding together, causes battery sealing-performance poor, is easy to form gap, in addition internal structure is not compact
It is inconsistent with sealing process, it is serious to result even in electrolyte leakage, battery leakage, the service life of battery is generated very big
It influences, it is therefore necessary to propose a kind of new good airproof performance, zinc-air battery at low cost.
Utility model content
The purpose of this utility model is to propose a kind of novel short cylindrical zinc-air battery, can admit air into battery just
Pole, and solve the problem of zinc-air battery poor sealing battery leakage.
This pillar zinc-air battery includes：Metal shell, plastic inner shell, ventilation net, positive plate, electrolyte, negative plate.
The metal shell is made of 304 stainless steels, and main function is to increase battery appearance surface hardness and resistance to old
Change degree wraps internal plastic inner shell, maintains inside battery stable structure；
The plastic inner shell is made up using polytetrafluoroethylplastic plastic of injection molding process, and outside battery metal
Shell is seamlessly connected, and effect is sealed cell internal structure, prevents electrolyte from revealing；
The ventilation net, is made, electroplating surfaces with tin of copper mesh.
The positive plate, main composition have：Carbon dioxide adsorption layer, waterproof ventilative layer, carbon felt, diaphragm paper；
The negative plate, is mainly made of calamine cream.
Compared with prior art, the utility model has the following advantages：
1, using novel short cylindrical structure, battery surface metal shell is seamlessly connected with plastic inner shell, plastic inner shell packet
Wrap whole internal structures, the passing battery of effective solution is glued since internal structure is not compact or sealing process is inconsistent
Even not close, caused electrolyte leakage problem.
2, carbon dioxide adsorption layer is increased in the utility model, in positive plate, facility and ventilation are off the net, for absorbing sky
Carbon dioxide in gas can effectively avoid the carbonating of electrolyte.
Description of the drawings
Fig. 1 is the outline drawing of the utility model；
Fig. 2 is the utility model vertical view；
Fig. 3 is the sectional view of the utility model A-A.
The reference numerals are as follows：
1, metal shell；2, ventilation net；3, plastic inner shell；4, carbon dioxide adsorption layer；5, waterproof ventilative layer；6, carbon felt；
7, diaphragm paper；8, electrolyte；9, calamine cream.
Specific implementation mode
Illustrate the technical solution of the utility model in order to clearer, the utility model is done further below in conjunction with the accompanying drawings
Detailed description.
A kind of short cylindrical zinc-air battery, shape are short cylindrical shape, and outer surface is metal shell (1), with inside
Plastic inner shell (3) is seamlessly connected, and upper surface is provided with one piece of circular vent net (2).Plastic inner shell (3) inner cavity is the reaction of battery
Position is followed successively by carbon dioxide adsorption layer (4), waterproof ventilative layer (5), carbon felt (6), diaphragm paper (7), electrode solution from top to bottom
(8), calamine cream (9).
Carbon dioxide adsorption layer (4) described in the utility model mainly takes the modes such as lamination to be formed by calcium hydroxide,
To absorb the carbon dioxide in air, electrolyte is prevented to be acidified；
Waterproof ventilative layer (5) described in the utility model prevents moisture in air from entering electricity using polytetrafluoroethylene film
Inside pond, lead to electrolyte dilution；
Diaphragm paper (7) described in the utility model, using filter paper, effect is only electrolyte to be allowed to pass through；
This pillar zinc-air battery biggest advantage is that battery wrapping property is good, and leakproofness is strong, effectively avoids battery
The phenomenon that leakage.And the utility model, the bodily form is small, makes simply, easy to process, the cost of material is low.Not opened in battery makes
With under state, it can prevent air from entering from ventilation net by pasting plastic foil to battery surface, extend the service life of battery.
The foregoing is merely the preferred embodiments of the utility model, are not intended to limit the utility model, all at this
Within the spirit and principle of utility model, made by all any modification, equivalent and improvement etc., should be included in the utility model
Protection domain within.
