Abstract
The invention discloses a water-activated magnesium battery which comprises a magnesium cylinder, a catalyst, a steel shell, bottom paper, coated paper, a carbon rod, water absorbing paper, a bracket, a waterproof film, a water filling cap and the like. When being preserved under dry sealing conditions, the water-activated magnesium battery can not be corroded and has favorable storage performance. When water is filled to perform activation, the water-activated magnesium battery can be used immediately and can not be subjected to voltage hysteresis. During water filling, the waterproof plastic film is bent; and after water filling, the waterproof plastic film is reset, thereby effectively preventing liquid and catalyst powder from overflowing through a water filling hole. The effective period of the water-activated magnesium battery can be up to 20 years or above, thereby being especially suitable for preservation for emergency and disaster relief.
Description
Technical field
The present invention relates to the battery technology field, specifically a kind of water filling magnesium cell.
Background technology
Magnesium alloy compares with kirsite that electrode potential is lower, electrochemical equivalent is less and conductivity is better, is more preferably battery anode material.But, because the magnesium alloy electrochemical properties is too active, so when as battery anode material, can produce the series of negative effect (such as: 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 anode faraday Efficiency Decreasing.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 invention provides a kind of rational in infrastructure, magnesium inter cell that electro-chemical activity that namely have magnesium has again good storge quality.
A kind of water filling magnesium cell comprises magnesium cylinder, catalyst, box hat, base stock, diaphragm paper, carbon-point, blotting paper, support, water proof plastic film and water filling cap.
The magnesium cylinder is the positive pole of battery, and base stock is located at magnesium cylinder bottom, and magnesium cylinder medial surface is provided with pulp layered paper (not mercurous diaphragm paper), catalyst filling in the magnesium cylinder chamber.Box hat one end opening, the magnesium jacket casing places in the box hat cavity.The main body of carbon-point is vertically inserted in the catalyst, and the one end stretches out outside the box hat opening.Blotting paper is overlying on catalyst surface, and the edge frame of support is in magnesium cylinder sidewall.Support is the cellular plastic sheet, also is provided with fixed cover on the support, moves to prevent blotting paper.The water filling cap comprises some water filling through holes, and the water filling hat brim is along closely cooperating with box hat opening part inwall, and and support between form air chamber.Water-separating film is overlying on water filling cap bottom surface, with sealing water filling through hole.The water filling film is made by the material with elasticity and intensity, as: plastics.
Water filling magnesium cell of the present invention, the paper circle that pulp layered paper surrounds are in order to form catalyst case, to isolate with the magnesium cylinder.Blotting paper can when from the water injection hole injected water, can make water fast by blotting paper for quick absorbent materials such as nonwoven fabrics, with catalyst reaction, reaches the effect of repid discharge.The support of frame on the magnesium cylinder can prevent that blotting paper from moving.Set fixed cover on the support is sheathed on outside the one section carbon-point that is positioned at the air chamber place.When the effect of water-separating film was fast water injection, anti-sealing overflowed from water injection hole, prevents that also grained catalyst from spilling simultaneously.Water-separating film is the film plastics, and when injector passed from water injection hole, waterproof membrane was crooked, and water arrives air chamber, by support, to absorbent paper layer.For ease of water filling rear enclosed water injection hole, fixed cover or water filling cap bottom surface are fixed in the part of water-separating film.
Corrosion not when water filling magnesium cell of the present invention is preserved under the condition of drying sealing has good storge quality.After water filling activates, can use immediately, the voltage delay phenomenon does not occur.The water proof plastic film bends during water filling, and the complete rear water proof plastic film of water filling resets, and prevents that liquid and catalyst fines from overflowing from water injection hole.This water filling magnesium cell term of validity can reach more than 20 years, was particularly suitable for the emergency disaster relief deposit.

Fig. 2 is that water filling magnesium cell water filling cap of the present invention water filling is schematic diagram.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail.
As shown in Figure 1.Water filling magnesium cell of the present invention, the just very magnesium cylinder 1 of its battery, base stock 6 is located at the end inner face of magnesium cylinder 1, magnesium cylinder 1 medial surface is provided with pulp layered paper 7, catalyst filling 3 in the magnesium cylinder chamber, catalyst 3 is for being selected from magnesium chloride, magnesium nitrate, activation electrolytic manganese dioxide, water-absorbing resin, one or more in active carbon and the sodium chloride.Box hat 2 one end openings 21, magnesium cylinder 1 is placed in box hat 2 cavitys.The main body of carbon-point 4 is vertically inserted in the catalyst, and the one end stretches out outside the box hat opening 21.Blotting paper 5 is overlying on catalyst 3 surfaces, and the edge frame of support 8 is in magnesium cylinder 1 sidewall.Support 8 is the cellular plastic sheet, also is provided with fixed cover 81 on it, moves to prevent blotting paper 5.Water filling cap 9 comprises some water filling through holes 91, water filling cap 9 edges and box hat opening 21 place's inwall tight fits, and and support 8 between form air chamber 22.Water-separating film 92 is overlying on water filling cap 9 bottom surfaces, with sealing water filling through hole 91.Fixed cover 81 or water filling cap 9 bottom surfaces are fixed in the part of water-separating film 92.
As shown in Figure 2, during water filling, injector 10 1 ends promote water-separating film 92 through water filling through hole 91, and water-separating film 92 stressed generation elastic deformations are bent downwardly, and make water inject air chamber 22.After the water filling, external force disappears, and water-separating film 92 is again with 91 sealings of water filling through hole.
