Abstract
The present invention relates to an injection style zinc-air battery device which is characterized in that extrusion type fuel tank containing zinc mush is connected with the connecting interface in sealing components of zinc-air batteries; one side of air electrode of the zinc-air batteries is close to membranes, and the other side is positioned towards the air; the air electrode and fluid collector are respectively lead out by wires and are used as the positive and negative poles of the batteries. A vortex gate which is provided with meshes and is made of insolating materials is used for making the fluid collector, the membranes and the air pole transversely fixed and dividing a reacting layer between the fluid collector and the membranes into a plurality of zinc mush flowing spaces communicated by meshes. By extruding the fuel tank, the conveying of the zinc mush toward the inner parts of the batteries can be realized, which makes the zinc mush flowing in the reacting layer flow over big areas without pressure difference. Simultaneously, a zinc pole structure which is adverse to high-current work is damaged, which makes the zinc mush maintaining in high activity. The utilization ratio of zinc can be improved from 70 to 80 % under the condition that the zinc mush is not replaced, and the utility model can be used as motive power supply of a motor vehicle.
Description
Technical field:
The invention belongs to the battery technology field, particularly can be used as the injection style zinc battery device of electric motor car electrical source of power.
Background technology:
" battery " (1999 4 monthly magazines, the 29th the 4th phase of volume p76-80) have been analyzed zinc electrode flash-over characteristic and the method that improves battery capacity, and these methods mainly are to add suitable electrolysis additive, can reduce chemical method.In fact, zinc electrode is when heavy-current discharge, and fine and close zinc oxide film that electrode surface forms and special electrode structure can cause the entire electrode passivation very soon, thereby lose the ability of heavy-current discharge.Even select suitable additive, the utilance of zinc also has only 20% to 30% under the big current condition.
" battery " (2002 10 monthly magazines, the 32nd the 5th phase of volume p294-297) have been introduced several circulation active material electrodes, and the pastel that is about to zinc powder and electrolyte pumps into inside battery, carries out electrode reaction by collector, and reaction product flows out battery with slurry.Chinese patent application number 01812639.1 discloses a kind of fuel container and recovery system that is used for device for converting electric energy, used anode material is that the fluid that the gel electrolyte of 65% metal powder and 35% is formed is stuck with paste, its gel electrolyte is 5% polyacrylamide, 35% KOH and water, and recovery system is to hold the apotheca of scrap anode material.This anode material is by flowing, replace blending, change the structure of each material in the zinc electrode mixture on the one hand, made it more to help the reaction of zinc electrode, improved the utilance of zinc, the zinc apotheca of peripheral hardware has also enlarged battery capacity on the other hand, and the zinc of being convenient to simultaneously more renew is stuck with paste.Yet the prior art scheme all adopts the paste of the zinc in the single fuel tank is assigned in each monocell by pump and valve.Conduct electricity because zinc is stuck with paste, do not cause short circuit when requiring distributing valve to switch, realize very difficulty on the technology.It is a kind of mixture that contains highly basic that zinc is stuck with paste, and viscosity can become again greatly in course of reaction, and the pump on the general industry is difficult to meet the demands, and needs the special pump valve system of development could solve this technical barrier.Flow channel in the existing battery, a kind of is the reaction compartment that constitutes by between zinc collector and the barrier film, after the zinc magma pump is gone into battery, it is very disadvantageous that the structure of this reaction compartment flows for the replacement of fluid, reacted zinc is stuck with paste and is entered the zinc paste of battery and only replaces on sprue, some dead angles in the flow field then do not have to replace flows, and will lump and lose activity in these positions, long-time reaction back, thereby cause the power of battery to descend; Also having a kind of is the zigzag that above-mentioned reaction compartment is divided into connection, make that fluid can inswept more reaction surface, yet this structure only is fit to gas, zinc is stuck with paste this full-bodied fluid, it is flowed in flexuose long passage, must impose severe pressure, one consumes energy greatly, uneconomical, moreover high-pressure fluid may wear out barrier film, flows away from other easier mobile passages, causes the damage of battery.
Technology contents:
