Description
Technical field
The utility model belongs to the electric automobile applied technical field, specially refers to a kind of nanometer zinc air driven battery of electric automobile special use.
Background technology
Along with the development of society, the car owning amount of China is increasing, and environmental pollution, energy shortage problem are also serious day by day.And present electric automobile belongs to conventional automobile repacking mostly, adopts common driving battery, as iron ion, lithium ion battery etc., has shortcomings such as cost height, mileages of continuation weak point.Therefore, the driving battery that needs a kind of electric automobile special use of development.
The utility model content
In view of this, the purpose of this utility model provides the nanometer zinc air driven battery of a kind of cost performance height, energy storage density is big, mileages of continuation is long, security performance is high electric automobile special use.
To achieve these goals, the utility model is by the following technical solutions:
A kind of nanometer zinc air driven battery of electric automobile special use comprises housing, and wherein, described housing is provided with the negative electrode that anode and zinc powder and electrolyte mixture are formed, and described anode is provided with anti-leakage layer, and described negative electrode is provided with separator; Described anode is the anode that the airborne oxygen of charcoal absorption is formed.
As preferably, described housing is provided with pore.
As preferably, also be provided with the insulated enclosure layer on the described anode.
As preferably, described anti-leakage layer is the nanometer anti-leakage layer.
The beneficial effects of the utility model are:
The utility model nanometer zinc-air cell has the ability of big electric current continuous discharge, can satisfy the requirement that electric automobile accelerates and climbs continuously fast, with old-fashioned zinc-air cell energy storage capacity by 180～230Wh/kg, bring up to 1350Wh/kg, cost is low, no leakage, discharge and recharge often stable performance.
The utility model is special fuel cell, is the new generation of green storage battery, and aufbauprinciple is identical with dry cell, and difference is that its battery depolarizer is taken from airborne oxygen, does not take the battery volume.Therefore inside battery can carry more zinc, and specific energy is higher, and as electric automobile power battery, mileages of continuation is long.
The utility model low cost of manufacture, nontoxic, pollution-free, specific power is high, specific energy is high, the recyclable regeneration of raw material, and is simple in structure, low price, and superior performance, abundant raw materials, cost is low, is 1/5th of lithium battery.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being apparent to those skilled in the art to investigating hereinafter, perhaps can from practice of the present utility model, obtain instruction.Target of the present utility model and other advantages can realize and obtain by specifically noted structure in following specification or the accompanying drawing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below by specific embodiment, and by reference to the accompanying drawings, preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, be provided with the anode 1 that the oxygen in active carbon 2 absorbed airs is formed in the housing of the present utility model, the negative electrode 3 that zinc powder 4 and electrolyte mixture are formed, anode 1 is provided with nanometer anti-leakage layer 8 and insulated enclosure layer 5, and negative electrode 3 is provided with separator 6.Housing 1 is provided with a plurality of pores 7.
Energy storage principle of the present utility model is: become the zinc powder of pasty state, be adsorbed on the anode carbon of cathode terminal and a catalytic action.The airborne oxygen of Kong Kerang on the battery container enters on the carbon that cavity is attached to anode, and the zinc of negative electrode is oxidized simultaneously.Air must enter into anode incessantly, has aperture so that oxygen enters continuously at anodal housing, makes battery produce chemical reaction.
The carbon that plays catalytic action absorbs oxygen as anode from air, the mixture of zinc powder and electrolyte becomes pasty state as negative electrode, electrode solution is the KOH aqueous solution of high concentration, and separator is used for isolating the movement of two inter-stage solid powder/particles, and separator, anti-leakage layer and insulated enclosure layer are the nano-nylon material.The battery outer surface adopts the nickel metal shell.
The utility model is the basic skills of utilizing the basic principle of surface chemistry and electrochemistry, dynamics catalysis, cell body to zinc-air cell carries out oxidation processes, the corrosion fatigue life on the cell body surface of zinc-air cell can prolong 30 years, change zinc granule for zinc-air cell condition is provided, can not trickle charge problem and the few problem of trickle charge number of times thereby solved zinc-air cell.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
