Abstract
The present invention relates generally to the use of an oxygen concentrator to supply fairly high purity oxygen under pressure to a zinc/oxygen battery. The oxygen is supplied in a controlled manner.
Description
Technical field
The present invention relates generally to and use oxygen concentrator to import quite high-purity oxygen adding to depress in zinc-oxygen battery.Oxygen is imported in a controlled manner.
The background of invention
Metal-air battery uses a plurality of electrochemical cells, and this each battery is made up of a breathable negative electrode, metal anode and aqueous electrolyte.Because as the reactant in the electrochemical reaction, it is not heavy material, so metal-air battery has high energy density from airborne oxygen in their uses.In the process of zinc-air battery discharge, be transformed into hydroxide ion from the oxygen of surrounding air at negative electrode, zinc reacts and oxidized at anode and hydroxide ion, discharges the electronics energize.
A problem of zinc-air battery is to enter battery with gate or valve control oxygen.When battery must not closed oxygen to electric the time, then in use again oxygen flow is adjusted to load to be complementary.Second problem is the water of control inside battery.The 3rd problem is that oxygen is distributed in the cathodic region in the battery, so that make all oxidations effectively of whole zinc.
A solution of these problems is to import compressed air in battery.The difficulty of this system is, flows through battery in volumes of air and supplies with under the condition of oxygen, controls humidity and temperature in the battery well.
An object of the present invention is to use oxygen concentrator adding the problem that solves air stream in a controlled manner toward the quite highly purified oxygen of zinc-oxygen battery input of depressing.This and other purpose of the present invention will be by being clear that in the following description.
The general introduction of invention
The invention provides a kind of solution infeeds the problem of oxygen in metal-air battery preferred version.The present invention discloses oxygen concentrator is used in combination with zinc/oxygen cell, and wherein oxygen is imported with controlled manner.
The description of accompanying drawing
Fig. 1 is the flow chart that is used in combination oxygen concentrator in battery.
The detailed description of invention
Metal-air battery comprises the anode that is made of metal, and this anode is in the discharge of metal-oxygen cell Can be oxidized in the journey, produce electric energy. This metal comprises lead, zinc, lithium, iron, cadmium, aluminium and magnesium. Zinc Normally preferably, because obtain easily, energy density height, security are good, and expense is lower. Electricity Also to provide electrolyte in the pond. Usually the electrolyte of the hydroxide of life cycle table the I family metal is water-soluble Liquid. For example, lithium hydroxide, NaOH, potassium hydroxide, cesium hydroxide etc.
Metal-air battery has the breathable negative electrode.
The oxygen that the present invention uses oxygen concentrator to supply with replaces air as reactant.Because air only contains 20% the oxygen of having an appointment, the air of flow could provide required oxygen for negative electrode so need greatly.To the breathable negative electrode, just can simplify battery design with concentrating the oxygen supply that obtains.
Use is by battery or flow through the rotary compressor (1) that the air stream of driving vehicle drives and produce compressed air.Also can use various compressors by feedback loop control.Air also can pass through on the water, to its humidification.This increases profit device (3) and can be placed on before or after the oxygen concentrator (5), but better is to be placed on after the oxygen concentrator.Compressed air is by oxygen concentrator, be equipped with in this oxygen concentrator to allow＞95% oxygen is by discharging the molecular sieve or the barrier film of nitrogen.The oxygen that concentrates comprises a spot of carbon dioxide, nitrogen G﹠W, is called " high-purity oxygen ".
Oxygen concentrator uses zeolite molecular sieve or absorber material preferably.The active carbon molecular sieve that absorbs argon gas also can combine use with zeolite.The capsule (7) that carbon dioxide from the Oxygen Flow that oxygen concentrator is discharged can be equipped with absorber material such as calcium oxide or lithium hydroxide absorbs.Before oxygen was discharged from capsule or entered inspissator, it can be by humidification (9).Under very dry weather condition, use water receiver (11).The profit device valve of being controlled by the moisture transducer in the battery (19) (13) that increases can be used for the amount of moisture that control enters battery (15).Use Oxygen Flow metered valve (17) control to enter the amount of oxygen of battery.
Oxygen enters the flow of battery and will control to such an extent that be complementary with cell load (23).The compressed oxygen air-flow should guarantee that also oxygen mixes or dispersion fully in whole oxygen electrode.Use pressure-reducing valve (25) that remaining gas and moisture are discharged in the atmosphere.
This battery comprises pressure-reducing valve, so that nitrogen and moisture are discharged in the air.Adopt the regenerative flush out stream or use two zeolite beds that nitrogen is desorbed from zeolite.In the circulation of two steps, a bed or a pair of (one is zeolite, and another is a carbon) are accepted pressure-air as feeding gas, and this pressure-air is to the bed pressurization and form Oxygen Flow.Simultaneously, the gases at high pressure in another are discharged and are reached lower pressure, and this step-down process is to the nitrogen and the argon gas (referring to laid-open U.S. Patents 4,880,443 in 1989) of absorption play the desorb effect in advance in the stage in cycle of higher pressure.
Although should use oxygen concentrator, also be useful on the less oxygen concentrator of making smaller batteries at the macrocell that is used for motor vehicle.
The situation of apparent load, the oxygen intake with air control system for air during beginning is arranged on the preposition, infeeds the amount of oxygen of battery in order to control.
In order to ensure the whole surface reaction of Oxygen Flow and negative electrode, can change the direction of Oxygen Flow with a plurality of baffle plates (21) that are placed in the oxygen channel.The baffle plate that is used to change the Oxygen Flow direction limits one and cover its serpentine channel of having a few basically on cathode surface.Be preferably, negative electrode contains an inlet, an outlet and a plurality of baffle plate, so that limit a tortuous passageway that makes oxygen flow to outlet from inlet.
A kind of catalyst component can be placed in the passage of Oxygen Flow, so that the hydrogen that the rechargeable metal-oxygen cell of catalysis produces and the combination again of oxygen.
Oxygen concentrator technology that can this is identical is applied to use the fuel cell of hydrogen as anode.Oxygen concentrator provides a more efficiently source of oxygen for these batteries.Airborne carbon monoxide can be poisoned fuel cell.Use the oxygen concentrator source of oxygen of purifying to prevent or reduce this interference that the carbon monoxide that exists in the air and other impurity cause.
