Abstract

The utility model provides a saline cell, falling in between the primary cell and the accumulator cell. The utility model has the advantages that the novel cell does not need charging apparatus; the generated electrolyte does not pollute environment; the utility model can be used in dry environment and store spare novel power supply for a long time. Compared with the accumulator cell, the utility model has the advantages of small size, light weight, no corrosion, and long service life; what the saline cell needs to do is to change an anode plate. Compared with the dry cell, the cost of the utility model can be lowered by 70%, and the utility model can drive miniature electrical appliances below 6 v in the situation without power supply.

Description

Salt battery

The present invention relates to a kind of salt battery between primary cell and storage battery, belong to technical field of electrochemistry, its IC is H01M12/06 due to.

At present the workman of mine work, or the trackwalker of railway, as run into special circumstances can not be timely in accordance with regulations time when returning, because of just exhausting, power supply can not change the storage battery of carrying, thereby influence normally carrying out of work, and have can the one-tenth accident, or threat to life.If adopt dry cell then not only cost an arm and a leg but also be unfavorable for carrying.As what will carry is this power-supply device of the present invention, above-mentioned situation just can not take place, end user's scream can in time will be carried salt solution according to the brightness of lamp and will be ready to, can be under the situation of feeling about in the dark time of 1 minute just power supply can be installed again, 10-15 is after second, the power supply supply that reaches more than 10 hours can be provided again, and can repeatedly repeat aforesaid operations, thereby obtain sufficient power supply.

Because each metal all has it that its electrode potential is arranged, and the difference in Electrode Potential of each metal is all inequality.Just providing a kind of is exactly to have utilized two kinds of metals to listen difference in Electrode Potential, and produces electric current.

The present invention's purpose just provides a kind of charging device that do not need, and the electrolyte that is produced is free from environmental pollution.Can be in the environment of drying, long preservation is standby.Compare with storage battery, volume water, in light weight, non-corrosiveness.Long service life only needs to change positive plate.Compare with dry cell, expense reduces about 70%.Under the non-transformer situation, can drive the following compact electric apparatus of 6W.

Describe the present invention in detail below in conjunction with accompanying drawing

Fig. 1 is the present invention's structural representation

This salt battery is by battery case (4) substantially, positive plate (1), minus plate (2) and electrolyte (3) consist of, positive plate (1) is to be made by magnesium metal (Mg), and minus plate (2) is to be made by electrically conductive graphite, Electrolyte (3) is to be formed by salt and dark the closing of water. Its profile of positive plate (1) made from magnesium metal (Mg) Geometric shape should be the plate of 160 * 95 * 4mm, and its shape of cloudy plate (2) made from electrically conductive graphite is several The plate what type shape is answered 160 * 95 * 0.5mm. The best effort distance of positive plate (1) and minus plate (2) From should be less than 10mm. The content that is made of its magnesium metal of positive plate (1) magnesium metal (Mg) should be 80%. Electrolyte (3) is to be mixed into 350g water and 40-50g salt, and its concentration should be 10-12%. Electricity Pond container cover (5) should be integrally formed with battery lead (6), so that the dismounting maintenance. Salt for subsequent use locker room (7), its volume should be able to be to place 200g salt as standard. Battery lead (6) connects sun with the form speed of series connection Pole plate (1) and cloudy plate (2) are to consist of battery pack.

According to above-mentioned specification requirement, the 350g light water is being housed, in the situation of 40-50g edible salt, After 10 seconds-15 seconds, just can produce the voltage of 2.5--4.0v, and can be with a 2.2v small electric bulb point Bright and luminous, about the electric current 1.0A in the road, every use (can be decided according to brightness) more than 10 hours Change primary brine. Every cover positive plate can use more than 10 times (100 hours), with after can change the moon Pole plate need not be changed.

As think the too low Method for Area that adopts the reaction that strengthens cathode-anode plate of above-mentioned voltage; As think that service time is long, too short, can on the thickness of anode, take in.

This battery use is extensive, and is easy to use, can be made into the hand lamp formula, is used for illumination; Can be used for field work, rescue, tourism, geology archaeology, on light fixture, increase filter and can do signal lamp usefulness.Also can repack the flashing light alarm class into; Also can make Backpack type, waist-carrying formula, portable with it as power supply use separately; Lamp can be made the adjustable forehead lamp of direction, flashlight etc.
