Abstract
The utility model relates to a battery and particularly relates to a zinc-air aerodynamical battery. The utility model comprises at least one battery monomer provided with an air inlet connected with an atomic oxygen generator. The utility model has the advantages that as atomic oxygen (O#-[3]) has strong oxidizing property, the reaction with the zinc cathode is enhanced, and accordingly, the current output capacity is greatly improved.
Description
Affiliated technical field
The utility model relates to a kind of battery, particularly a kind of zinc-air force battery.
Background technology
At present, known zinc-air force battery is positive pole with airborne oxygen, and metallic zinc is a negative pole, and potassium hydroxide is electrolyte.In use, following shortcoming is arranged: moment maximum output current little; The zinc negative pole with the electrolyte course of reaction in generate zinc oxide (ZnO), zinc oxide is attached to the metallic zinc surface, passivation the zinc negative electrode, hinder reaction, reduced the battery fan-out capability; Granular metal zinc density very easily is deposited on the battery cavity bottom much larger than electrolyte, has reduced the cathode area corresponding with anode, influences the battery fan-out capability.
Summary of the invention
The utility model provides a kind of moment maximum output current big zinc-air force battery.Its technical scheme is: zinc-air force battery comprises at least one battery cell, and gas input port is arranged on the battery cell, has the atomic oxygen generator to be connected with gas input port.Beneficial effect is: because atomic oxygen (O
3) extremely strong oxidizability is arranged, strengthen the reaction with the zinc negative pole greatly, thereby significantly improved the electric current fan-out capability.
Be arranged in the battery cell chamber ultrasonic oscillator is arranged.Because metallic zinc is harder, and zinc oxide is softer, the ultrasonic wave that ultrasonic oscillator produces has good cleaning action to the zinc oxide that is attached to the metallic zinc surface; Electrolyte turbulence under the ultrasonic wave effect simultaneously drives granular metal zinc and quivers in electrolyte, has eliminated deposition, has increased the cathode area corresponding with anode.
Above-mentioned ultrasonic oscillator or atomic oxygen generator are connected with same pulse signal generator, and this pulse signal generator is connected with cyclelog.(20～30KHz) excite the frequency optimum traffic of device exactly identical with atomic oxygen, use same pulse signal generator can freely control ultrasonic oscillator or atomic oxygen generator under the control of cyclelog because the suitable operating frequency of ultrasonic waves for cleaning.
The above-mentioned gas input port comprises two rectangle spouts.Atomic oxygen can participate in reaction to greatest extent after ejection.
Description of drawings

Fig. 2 is zinc-air force battery cell structural front view;
Fig. 3 is zinc-air force battery cell structure side view.
1. cell housings among the figure, 2. ultrasonic oscillator, 3. ultrasonic oscillator lead-in wire, 4. ultrasonic oscillator signal input terminal, 5. gas input port, 6. spout, 7. electrolyte, 8. granular metal zinc, 9. graphite anode plate.
Embodiment
As shown in Figure 1, pulse signal generator produces the impulse wave that frequency is about 20～30KHz, one tunnel ultrasonic oscillator that sends in the battery cell produced ultrasonic wave after this impulse wave was amplified by pulse power amplifier, another road is sent to the atomic oxygen generator, produces atomic oxygen and is transported in the battery cell.Cyclelog regularly starts ultrasonic oscillator in order to timely cleaning zinc particle, and the only work when starting of atomic oxygen generator.The utility model is particularly suitable for the power source as electric motor car etc.
As Fig. 2, shown in Figure 3, electrolyte 7 is arranged in cell housing 1, soaking in the electrolyte 7 has graphite anode plate 9 and granular metal zinc 8.At cell housing 1 top gas input port 5 is installed, gas input port 5 is communicated with two rectangle spouts 6, and the gas of ejection prolongs graphite anode plate 9 outwardly deployings from spout 6.In cell housing 1 bottom ultrasonic oscillator 2 is installed, ultrasonic oscillator 2 is connected with pulse signal generator by ultrasonic oscillator lead-in wire 3, ultrasonic oscillator signal input terminal 4.
