Sodium hydroxide or potassium hydroxide solution can be used.Cathode aluminium sheet and electricity can be constantly consumed in aluminium-air cell discharge process
Liquid is solved, does not need to recharge after battery discharge, replacing electrode plate and supplementing electrolyte can be realized re-discharge.Aluminium is empty
In the stand-by state, self-corrosion can occur for cathode aluminium sheet and electrolyte contacts, and aluminium sheet and electrolyte can be consumed constantly in pneumoelectric pond, cause
Make energy loss.
Summary of the invention
The present invention In view of the above shortcomings of the prior art, proposes a kind of detachable aluminium-air cell device, can
It is simple and quick to separate electrode and electrolyte, and control reaction immediately starts and stops, and improves battery.
The present invention is achieved by the following technical solutions:
The present invention includes: battery pack and the electrolyte stocking system being flexibly connected therewith, which includes:
Two are imported and exported the electrolyte reserve tank being selectively connected to by electrolyte, and an electrolyte reserve tank is connected with battery pack, separately
One electrolyte reserve tank is equipped with electrolyte note row's mouth, when needing battery pack to stop working, opens electrolyte inlet and outlet and opens
It closes, electrolyte flows out battery pack, flows into electrolyte tank, and electrode is separated with electrolyte, stops electric discharge；When battery needs to put again
When electric, cell apparatus is inverted, electrolyte flows back in battery pack, and realization is discharged again.
The electrolyte stocking system is connected by strainer with battery pack, so that the insoluble of generation is put in discharge process
Electric collection of products not only can be recycled discharging product and realize resource recycling in filter screen, but also battery work can be improved
Make efficiency.
Technical effect
Compared with prior art, electrolyte can be stored in electrolyte tank by the present invention in battery back up, make electrode
It is kept completely separate with electrolyte, thoroughly inhibits self discharge, avoid the loss of the energy content of battery, realize the long term storage of battery；The present invention
Filling electrolyte and free electrolyte can be fast implemented；Precipitating can be filtered out by installing filter screen, improve battery life with
Generating efficiency.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is that Fig. 1 is inverted schematic diagram；
In figure: 1 battery pack, 2 electrolyte stocking systems, 201 strainers, 202 sector movable baffles, 203 electrolyte inlet and outlet,
204 electrolyte reserve tanks, 205 electrolyte note row's mouth.
Specific embodiment
As shown in Figure 1, for one kind that the present embodiment is related to, wherein including: battery pack 1 and the electrolyte being flexibly connected therewith
Stocking system 2, the electrolyte stocking system 2 include: two electrolyte deposits being selectively connected to by electrolyte inlet and outlet 203
Case 204, an electrolyte reserve tank 204 are connected with battery pack 1, another electrolyte reserve tank 204 is equipped with electrolyte note row
Mouth 205.
The electrolyte stocking system 2 is connected by strainer 201 with battery pack 1, which is by round stainless steel
Outline border and internal double layers intersect stainless steel wire composition in length and breadth, and mesh number is 500 mesh.
The selectivity connection imports and exports the sector movable baffle 202 of 203 sides in fact by being rotatably dispose in electrolyte
Existing, the radius of the sector movable baffle 202 is identical as plan radius where electrolyte reserve tank, preferably has resistance to well
The property of soda acid and the polyethylene for sealing liquid are made.
As shown in Fig. 2, being first inverted cell apparatus, is infused from electrolyte and inject 4M sodium hydroxide solution 2L, electricity in row's mouth 205
Solution liquid is stored in electrolyte tank.When rotation electrolyte tank 204, open electrolyte inlet and outlet 203, electrolyte is electrolysed from 203
Liquid inlet and outlet outflow, flow into battery pack in discharge, simultaneously close off electrolyte inlet and outlet 203, then by cell apparatus be inverted to
Normal operating conditions as shown in Figure 1, the electric discharge work of battery normal continuous.
When battery does not need work, electrolyte inlet and outlet 203 are opened, electrolyte flows back to electrolyte tank under the effect of gravity
In, battery stops working.Since electrolyte is isolated with electrode plate, self-discharge of battery is not present, battery can long-term preservation.
When needing to discharge again, battery need to be only inverted, electrolyte will again flow into battery pack, and realization is discharged again.
After operating intermittently 1 month, split cell group and electrolyte stocking system, removal filter plate are cleaned, and obtain filtration product
12.3g.Filter screen is once purged, is placed again into cell apparatus, reuses.
Above-mentioned specific implementation can by those skilled in the art under the premise of without departing substantially from the principle of the invention and objective with difference
Mode carry out local directed complete set to it, protection scope of the present invention is subject to claims and not by above-mentioned specific implementation institute
Limit, each implementation within its scope is by the constraint of the present invention.
