Abstract
The utility model discloses a magnesium air cell. The air cell comprises a carbon rod, a magnesium drum, anode synthetic powder, inner diaphragm paper, outer diaphragm paper, an air anode shell, an outer shell, a water absorption layer, bottom bowl paper, a false bottom, a plastic cover and fixing rings. The air cell is not corroded when being stored under the condition of dry sealing and has good storage property. The air cell can be instantly used after being activated by water injection and is free from voltage lagging. A waterproof plastic film bends during water injection and resets after water injection, thus effectively preventing liquid and catalyst powder from overflowing via water injection holes.
Description
Technical field
The utility model relates to the battery technology field, the magnesium air cell that specifically a kind of battery capacity is big, environment friendly and pollution-free, storge quality is good.
Background technology
Magnesium alloy compares with kirsite that electrode potential is lower, electrochemical equivalent is littler and conductivity is better, is more preferably battery anode material.But, because the magnesium alloy electrochemical properties is too active, therefore when as battery anode material, can produce series of negative effect (for example: voltage delay and the perishable perforation of housing etc.).In most of electrolyte solutions, the magnesium alloy dissolution velocity is very fast, produces a large amount of hydrogen, causes the anode faradic efficiency to reduce.In addition, the existence of impurity element in the magnesium alloy has been accelerated magnesium alloy from corrosion reaction speed, generates to have certain thickness Mg (OH)
2Passivating film, severe inhibition the magnesium alloy anode active dissolution.Therefore, the utilance that improves magnesium-alloy anode material is focus and the difficult point of current magnesium alloy battery research, and its key problem in technology is the contradictory relation that solves between magnesium alloy anode activation and passivation.
Summary of the invention
The utility model provides a kind of rational in infrastructure, magnesium air cell that electro-chemical activity that namely have magnesium has the excellent storage performance again.
A kind of magnesium air cell is characterized in that comprising carbon-point, magnesium tube, anodal composite powder, inner septum paper, outer diaphragm paper, air anode cover, shell, water accepting layer, end bowl paper, the false end, vinyl cover and retainer plate; End bowl paper is located at the bottom of described magnesium tube, and the medial surface of magnesium tube is provided with inner septum paper, and the outside is provided with outer diaphragm paper, fills anodal composite powder in the magnesium tube chamber; Shell one end opening, magnesium jacket casing place in the shell cavity; The main body of carbon-point is vertically inserted in the anodal composite powder, and the one end stretches out outside the described shell aperture; Water accepting layer is overlying on anodal composite powder surface; The air anode cover is wrapped in outside the described outer diaphragm paper; Shell is buckled in outside the air anode cover, forms air chamber; Described retainer plate is set between the inwall of magnesium tube bottom and shell; Vinyl cover places the top of air anode cover, and chimeric and shell one end opening.
Water accepting layer, its medium can be blotting paper, prevents that anodal composite powder from overflowing.
The magnesium tube is anodal, is lined with not mercurous inner septum paper in the magnesium tube, and skin is outer diaphragm paper, prevents that the magnesium tube from corroding with the air contact.
Vinyl cover is provided with water injection hole.
Stretch out sheathed metal cap on the carbon-point end of magnesium alloy tube top end opening.
The utility model magnesium air cell does not corrode when preserving under the condition of drying sealing, has the excellent storage performance.After water filling activates, can use immediately, the voltage delay phenomenon does not take place.Injector directly injects clear water from water injection hole, by water accepting layer, enters into anodal composite powder.The air anode cover has the function of air-and water-permeable, and the air in the air chamber and magnesium socket joint touch, and form whole contact-making surface, and the augmenting response area can produce more electric weight.
