Embodiment
For above-mentioned feature and advantage of the present invention can be become apparent, special embodiment below, and coordinate appended accompanying drawing to be described in detail below.
Figure 1A is the three-dimensional exploded view according to a kind of aluminum-air cell of the first embodiment of the present invention.
Please refer to Figure 1A, a kind of aluminum-air cell 100 of the present embodiment comprises container 102, is positioned over battery pack 104, absorbent material 106, electrolyte 108 and active starting drive 110 in container 102.Battery pack 104 is to be made up of aluminium anodes 112 and air electrode negative electrode 114.Because electrolyte 108 is alkalescence, the neutral or acid aqueous solution, so be with film material 116 coating electrolytes 108, in order to avoid contact with battery pack 104 in the present embodiment.But this tunic material 116 is also non-essential, in the container of suitably design, can omit the film material 116 of this layer of coating electrolyte 108.Container 102 is generally non-conductor, and as the container of plastic cement system, and its structure can comply with required variation, and if Figure 1A is cylindric, but the present invention is not limited to this.The general position of air electrode negative electrode 114 is in the periphery of container 102, can with air reaction.
There is the mechanism that electrolyte 108 is initiatively contacted with battery pack 104 as for active starting drive 110; That is to say, the present embodiment is to reach by the movement of electrolyte 108 effect that electrolyte 108 contacts with battery pack 104, and battery pack 104 is not have action, and in passive state.About the detailed mechanism of active starting drive 110, will be in below describing.
In the present embodiment, aluminium anodes 112 can be fine aluminium or the aluminium alloy of purity 85wt.% to 99.999wt.%.If aluminium anodes 112 is aluminium alloy, can comprise at least one metal in magnesium, iron, copper, calcium, bismuth, indium, zinc, gallium, tin, cadmium, germanium, antimony, selenium, thallium and mercury.Taking magnesium as example, aluminium anodes 112 can be aluminium-5wt.% ~ 15wt.% magnesium alloy, but the present invention is not limited to this.In addition, the thickness of aluminium anodes 112 is for example between 1mm ~ 0.1mm.Aluminium anodes 112, except being bulk or film material as shown in Figure 1A, also can be porous web material.
In the present embodiment, air electrode negative electrode 114 can comprise catalyst.Such as metal oxide of described catalyst, as MnO
2or CoO; Or the catalyst of Pt/C and so on.
In the present embodiment, absorbent material 106 is for example the material being made up of cellulose or fiber, and above angle is observed the B region (as shown in Figure 1B) of Figure 1A, can find out that absorbent material 106 is around the aluminium anodes 112 and air electrode negative electrode 114 being filled in container 102, to can make need to use an aluminum-air cell 100 time electrolyte 108 be diffused into all sidedly aluminium anodes 112 with air electrode negative electrode 114 and contact with it.
In addition, in Figure 1A, also can have dividing plate 118 to be arranged between the film material 116 and battery pack 104 of coating electrolyte 108, and dividing plate 118 for example have multiple through hole 118a.But this layer of dividing plate 118 non-essential maybe can be omitted in the container of suitably design.
The described mechanism of active starting drive 110 is in the present embodiment a breaking plant, and the film material 116 that it has pointed cone 120 and can initiatively destroy coating electrolyte 108, makes electrolyte 108 contact with beneath battery pack 104.But just a kind of example wherein of the active starting drive 100 of Figure 1A, active starting drive of the present invention also can have other embodiment.When after the each Component composition in Figure 1A, as shown in Figure 1 C, the coated electrolyte 108 of tunicle material 116 is positioned in container 102 and does not contact mutually with battery pack 104, and active starting drive 110 is arranged on electrolyte 108 tops, and pointed cone 120 is towards electrolyte 108.In the time not using an aluminum-air cell 100, because electrolyte 108 is separated with battery pack 104, so can long-term storage, time to be used, only need mobile active starting drive 110 to destroy the film material of coating electrolyte 108, as shown in Fig. 1 D, can make the through hole 118a of electrolyte 108 direct penetrating clapboards 118 contact with beneath battery pack 104, and start electric discharge.Even by the container of Fig. 1 D 102 horizontal positioned or inversion, electrolyte 108 also can be via the battery pack 104 that is filled in aluminium anodes 112 and air electrode negative electrode 114 absorbent material 106 around and is diffused into series and parallel.
Fig. 2 A is the perspective view according to a kind of aluminum-air cell of the second embodiment of the present invention.
Please refer to Fig. 2 A, an aluminum-air cell 200 of the present embodiment comprises container 202, is positioned over battery pack 204, absorbent material 206, electrolyte 208 and active starting drive 210 in container 202.Battery pack 204 is to be made up of aluminium anodes 212 and air electrode negative electrode 214.Container 202, battery pack 204, absorbent material 206 and the electrolyte 208 of the present embodiment all can be with reference to upper embodiment, therefore repeat no more.
Because electrolyte 208 is alkalescence, the neutral or acid aqueous solution, so the mechanism of active starting drive 210 comprises dividing plate 216, pin 218 and plucking device 220.Dividing plate 216 is arranged between electrolyte 208 and battery pack 204, and in order to separate electrolyte 208 and battery pack 204, and dividing plate 216 has through hole, and 218 of pins are blocked this through hole, though and Fig. 2 A only show a through hole, the present invention is not limited thereto.And plucking device 220 is connected with pin 218, can in the time using an aluminum-air cell 200, pin 218 be pulled out from through hole 216a, as shown in Figure 2 B.
When pin 218 is after through hole 216a pulls out, the electrolyte 208 through hole 216a that can flow through contacts with battery pack, and battery pack 204 does not need action.And even if by the container of Fig. 2 B 202 horizontal positioned or inversion, electrolyte 208 also can be diffused into battery pack 204 by the absorbent material 206 being filled in around aluminium anodes 212 and air electrode negative electrode 214, and starts electric discharge.
Below enumerate an experimental result and verify the effect of above-described embodiment.
