Abstract

The battery, related to inverting chemical energy to electric power directly, adopts Ca,Mg,Sn,Pb,Si-containing aluminium plate as cathode, and Mn,Na,Mg,Si-containing carbon powder and copper net as anode. The anodes are fixed on battery casings. The invention battery can provide 40-60 W power continuously for more than 8 hrs.

Description

Aluminium-carbon electrode for primary cell

The invention belongs to direct conversion chemical energy is the electrical energy devices technical field.

In the prior art before the present invention, the battery variety that to relate to direct transformation chemical energy be electric energy is a lot, as lithium-manganese cell, and metal-slight alkalinity battery, metal-air battery, aluminium-excide battery, lead-acid battery etc.Announced in the CN91102148.5 patent application that a kind of employing aluminium alloy or magnesium makes anode, use carbon dust, catalyst, electric conducting material is made the good method of negative electrode, but this battery can only provide microampere order to milliampere electric appliance load electricity consumption of level, and the medium that adopts in its structure needs often to change or replenish, thereby its range of application is restricted.

The objective of the invention is to, provide a kind of and can make full use of chemical energy, allow the electric energy of its generation can provide the domestic lighting electricity consumption at least, and give vast rural area, mountain area, pastoral area, field work and all are difficult for the place of energized, provide a kind of simple in structure, easy to use, can carry out the aluminium-carbon electrode for primary cell that replenishes at any time.

Now the technology of the present invention solution is described below:

Battery of the present invention is made up of battery container, medium, negative electrode, anode; Cathode material is an aluminium sheet, wherein contain a spot of gallium, magnesium, bismuth, tin, anode is to be made by carbon dust, it is characterized in that: in the cathode aluminum plate except that containing above-mentioned little metal, also suitably add a small amount of plumbous, silicon, its optimal proportion is: plumbous 0.3～0.5%, tin 0.5～1%, gallium 1～3%, magnesium 0.2～0.3%, bismuth 0.4～0.5%, anode is the carbon plate of being made by carbon dust and copper mesh, wherein add manganese and a spot of sodium in the carbon dust, silicon, magnesium, optimal proportion is: manganese 10～20%, sodium 1～3%, magnesium 0.2～0.5%, silicon 0.1～0.15%, carbon anode plate are fixedly mounted on the battery container, and its one side is contacted with air, another side contacts with salt solution, and the concentration of medium salt solution is 2～3%.

Battery container of the present invention is the common plastics groove, and its big I designs according to actual needs, is 20 * 10 * 3(cm) to be advisable with length * wide * thick generally.During making, with carbon anode plate directly as a face of battery container.During use, cathode aluminum plate is inserted in the plastic channel, the salt solution (concentration of its salt can suitably be adjusted according to water temperature) of adding 2～3%, power line on anode and the minus plate is connect the load bulb, can produce the electric current of 400～500mA, the open circuit voltage of its monolithic battery can reach 1.5～1.8V, sustainable 8 hours of operating time, if above-mentioned monolithic battery is together in series or parallel, then can make the bulb of 40W bright more than 8 hours, general domestic lighting electricity consumption 40～60W gets final product, and therefore, 12～15 batteries just can meet the demands on the serial or parallel connection.

Now that description of drawings of the present invention is as follows:

Fig. 1: battery series connection of the present invention back schematic cross-section.

Wherein: 1, negative electrode 2, anode 3, battery container 4, medium salt solution 5, load

The present invention is a kind of very simple way, but has really solved problem, says to a certain extent, than the more economical convenience of torch battery, do not have that the battery has run down and buy nowhere or interim urgent need and the problem that do not have adopts this device battery, as long as after the disposable purchase, when needing illumination, only need can obtain electric consumption on lighting to pouring certain density salt solution in the battery container into, this is to the mountain area, the rural area, pastoral area, field work, the electric consumption on lighting of construction site etc. has special significance.

Claims

1, a kind of chemical cell, form by battery container, medium, negative electrode, anode, cathode material is an aluminium sheet, wherein contain a small amount of gallium, magnesium, bismuth, tin, anode material mainly is a carbon dust, it is characterized in that: except that containing above-mentioned little metal, also suitably add small amount of aluminum, silicon in the cathode aluminum plate, its optimal proportion is: lead 0.3～0.5%, tin 0.5～1%, gallium 1～3%, magnesium 0.2～0.3%, bismuth 0.4～0.5%; Anode is the carbon plate of being made by carbon dust and copper network, and wherein adding manganese and a spot of sodium, silicon, magnesium, optimal proportion are in the carbon dust: manganese 10～20%, sodium 1～3%, magnesium 0.2～0.5%, silicon 0.1～0.15%; Carbon anode plate is fixedly mounted on the battery container, and one side contacts with air, and one side contacts with medium salt solution.
