Abstract
The utility model relates to a sealed non-maintenance accumulator, which is composed of a sealed casing, a cover plate, a positive and a negative plates, a connecting strip, an electrode, a fiber interlayer and the electrolyte. The accumulator has the advantages of without adding the electrolyte and the distilled water, long service life, etc.
Description
The utility model relates to a kind of storage battery, particularly a kind of maintenance free cell.
Existing storage battery is because the intrinsic defective of its design itself, exist many can not satisfactory part.For example conventional storage battery will often be surveyed electrolyte density, adds electrolyte and distilled water, adjusts electrolyte density, and has only 1-2 useful life.Conventional accumulators all belongs to the open-type structure, and electrolyte overflows easily, can only just put, can not put upside down or be sidelong, and the electrolyte that overflows, acid mist meeting etching apparatus, use can make problem more serious on communication apparatus especially.The general reduction Plante-type plate that adopts such as conventional automobile storage battery, the current potential of giving vent to anger is low can to produce and overflow hydrogen, so must adopt open design.
In order to overcome above-mentioned defective, the utility model adopts Seal Design, and conventional accumulators is improved.
So the purpose of this utility model provides a kind of closed maintenance free accumulator.
The storage battery of the utility model design comprises cover plate on can, the shell, be loaded on grid that the positive and negative pole plate by being arranged alternately in the shell constitutes, will described positive and negative pole plate connect together respectively two conduct electricity intercell connectors, the pole that is connected with an end of described intercell connector respectively, fiber interlayer and the electrolyte between described positive/negative plate.
Further preferred feature of the present utility model is for being equipped with safety valve under cover plate, under super-high-current charging or overcharge conditions, the excess air that is produced is discharged by safety valve, and safety valve cuts out voluntarily then, keeps storage battery to be in sealing state.Can be negative pressure in the described storage battery, preferred pressure is lower than 300mmHg.Shell can adopt ABS plastic to make.Pole plate can be made by lead-calcium alloy, and this alloy has higher overpotential, can suppress hydrogen and separate out, and higher mechanical strength is arranged.Described fiber can be glass fibre, the superfine fibre of preferred diameter 10-50 μ, the further available glass fibre that is mixed with hydrophobic fiber.Can scribble conventional lead plaster on the described grid.Electrolyte can be used conventional electrolysis liquid such as sulfuric acid.
Further describe below in conjunction with drawings and Examples.
Fig. 1 is the profile schematic diagram of storage battery of the present utility model.
Fig. 2 represents the sealing plate on the battery cell case.
Fig. 3 is one group of grid structural representation of the present utility model.
1 expression negative plate among the figure, 2 expression positive plates, 3 expression fibers, 4 expression intercell connectors, 5 expression poles, 6 expression cans, the pole on the 7 expression shells, 8 expression sealing plates.
Embodiment
Storage battery of the present utility model comprises a can ［ 6 ］, cover plate on the shell ［ 8 ］, safety valve (not shown) under the cover plate, six be assembled in the shell by just being arranged alternately, negative plate ［ 2,1 ］ grid of Gou Chenging, with just described, two conduction intercell connectors ［ 4 that negative plate connects together respectively, 4 ' ］, the pole ［ 5 that is connected with an end of described intercell connector respectively, 5 ' ］, diameter between described positive/negative plate is fiber interlayer ［ 3 ］ and the electrolyte of 10-50 μ, the grid of this storage battery is by lead-calcium alloy (calcic 0.04-0.14%(wt)) make, in the storage battery is negative pressure, and pressure is below the 300mmHg post.The overpotential of this storage battery reaches more than 2.4 volts, and can reach 10 years useful life.
Claims (4)
1, a kind of closed maintenance free accumulator, two of it is characterized in that comprising cover plate on a can, the shell, be loaded on grid that the positive and negative pole plate by being arranged alternately in the shell constitutes, will described positive and negative pole plate connecting together are respectively conducted electricity intercell connectors, the pole that is connected with an end of described intercell connector respectively, fiber interlayer and the electrolyte between described positive/negative plate.
2, storage battery as claimed in claim 1 is characterized in that under cover plate safety valve being housed, and this valve is opened when having excess air to produce, and closes voluntarily behind the discharge gas.
3, storage battery as claimed in claim 1 is characterized in that described grid made by lead-calcium alloy.
4, storage battery as claimed in claim 3 is characterized in that described grid calcic 0.04-0.14%(wt).
