Abstract

The utility model provides an aluminum -air cell, its be use in the active carbon adsorption air oxygen as anodal, used the negative pole of aluminum sheet and the aluminum -air cell of electrolyte, the active carbon is two sets of sheet structures, the aluminum sheet sets up between two sets of active carbons, the active carbon with the aluminum sheet together square settle in in the electrolyte, lean on the liquid level department of electrolyte the outside of active carbon is provided with polymer membrane, polymer membrane will electrolyte and air separation, it has the catalyst to add in the electrolyte. The utility model discloses an aluminum sheet design space network is similar to fish gill structure to make the aluminum sheet can be fully and the electrolyte reaction, thereby improve the generating efficiency. On the other hand polymer membrane avoids contacting lead to rotten because of electrolyte is direct with the air, also can avoid electrolyte to spill the polluted environment simultaneously.

Description

A kind of aluminium-air cell

Technical field

This utility model relates to air cell, is especially a kind of aluminium-air cell.

Background technology

Aluminium-air cell is the battery generated electricity as fuel and air effect using metallic aluminium, and its anode is aluminum metal, and negative electrode is porous Carbon dust and the composite of carbon fiber.Aluminum and carbon material are the lightest, and the reactant of negative electrode is directly obtained by air, and therefore energy is close Spending the highest, theoretical discharge value calculates up to 8, more than 000Wh/kg.

The product hydrogen of the exoelectrical reaction of aluminum electrode chemical equation in alkaline solution such as following formula (1) and following formula (2) reacts institute Show.

Al+4OH-→Al(OH)4-+3e-；E=2.35V vs.SHE (1)

2Al+6H2O→2Al(OH)3+3H2 (2)

By current diplomatic data, aluminium-air cell actual energy density is beyond 300Wh/kg, than commercial lead-acid battery or nickel Hydrogen battery goes up the most greatly several times.Additionally, aluminum metallic material is only 1/7 price of nickel metal material, following material in volume production becomes This is the cheapest.The consumption of aluminum metal and reclaiming are not business-like obstacle, the resultant product main constituent after cell power generation For aluminium hydroxide or aluminium oxide, recycling can be passed through, owing to aluminium hydroxide or aluminium oxide are the mineral that nature exists, Even if the most directly abandoning, environmental ecology the most not being affected, being the battery of high environment affinity.

But, aluminium-air cell there is also the problem that charging is slower.Although aluminium-air cell contains high specific energy, but specific power Relatively low, charging and discharging speed is relatively slower, voltage delay.Due to it also occur that phenomenons such as battery leakages, so causing still having Part uses situation to also need to solve.

Utility model content

For solving above-mentioned technical problem, this utility model provides a kind of aluminium-air cell, and it is to use in activated carbon adsorption air The oxygen negative pole that as positive pole, employs aluminium flake and the aluminium-air cell of electrolyte, described activated carbon is two groups of laminated structures, Described aluminium flake is arranged between two groups of activated carbons；Described aluminium flake is the space network that 3D prints；Described activated carbon and described Aluminium flake together square is placed in described electrolyte, and the outside by the described activated carbon at the liquid level of described electrolyte is provided with high score Sub-film, described electrolyte is separated by described polymeric membrane with air；Described electrolyte is added with catalyst.

Further, described space network is net thick 0.05mm-2mm, mesh 0.01*0.01mm-0.1*0.1mm.

Further, described space network includes center-pole and branchial plate composition；Described branchial plate is that many group spread configurations are in described On center-pole.

Further, described polymeric membrane is that oxygen selective passes through film.

Further, described polymeric membrane is to select in polysulfones, polyether sulfone, Polyphenylene Sulfone, polyvinylidene fluoride, polyimides one Kind or several mixture.

Aluminium flake of the present utility model design space network, be similar to fish gill structure so that aluminium flake can fully be electrolysed Liquid reacts, thus improves generating efficiency.On the other hand polymeric membrane is avoided because of going bad that electrolyte directly causes with air contact, Electrolyte can also be avoided to spill simultaneously, pollute environment.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing to of the present utility model Embodiment is described in further detail.

As it is shown in figure 1, activated carbon 1 is two groups of laminated structures, aluminium flake 2 is arranged between two groups of activated carbons 1；Activated carbon 1 He Aluminium flake 2 together square is placed in electrolyte 4, and the outside by the activated carbon 1 at the liquid level of electrolyte 4 is provided with polymeric membrane 3, described electrolyte 4 is separated by polymeric membrane 3 with air.

As in figure 2 it is shown, the space network that aluminium flake 2 prints for 3D, network planning lattice are net thick 0.05mm, mesh 0.01*0.1mm.

It is arranged on center-pole 5 as it is shown on figure 3, space network is three row's branchial plates 6.

Obviously, above-described embodiment is only for clearly demonstrating example, and not restriction to embodiment.For institute For the those of ordinary skill in genus field, can also make other changes in different forms on the basis of the above description. Here without also cannot all of embodiment be given exhaustive.And the obvious change thus extended out or variation are still located Among protection domain of the present utility model.
