The invention relates to a liquid low-sodium silicate forming-solution used for a storage battery and a container formation method. The forming solution is prepared by mixing 5-15 parts by weight of silica sol containing 40-60wt% SiO2 with 15-25 parts by weight of water, then adding an inorganic acid into the mixture until the PH being 1-4, and magnetizing the mixture in a magnetic field having 1000-6000 gauss for 5-10 minutes to obtain a liquid low-sodium silicate forming-solution with its viscosity being less than 0.02mPas. The liquid low-sodium silicate forming-solution is poured into a battery container. Sequentially, the battery is formed by applying power to the battery at the room temperature for 30∼50 hours. By using the liquid low-sodium silicate forming-solution, a great amount of acid mist is thoroughly keeped from escaping in the period of formation during manufacturing the battery, thus to prevent environment from being polluted and an operator from being harmed. The battery won't generate heat at the time that it is formed, and the battery is sufficiently formed in the shortest time, because the forming solution is a fluid state with good fluidity. The storage battery thus obtained has 25C ∼ 30C discharge capacity.

A method for forming lead-acid batteries (2) that comprises the following stages: a first electrolyte (7) at a given concentration and constant temperature is collected from a first tank (5); said first electrolyte (7) is distributed to the batteries; said first electrolyte (7) is circulated continuously at predetermined and substantially constant concentration and temperature for a preset amount of time; said batteries are powered with a direct current during the circulation of said first electrolyte (7) for a given initial charge time; the circulation of said first electrolyte (7) is cut off and a second electrolyte (8) is circulated in said batteries, said second electrolyte being collected from a second tank (6), at a greater concentration than the previous electrolyte and at a preset and substantially constant temperature for a further preset time; said batteries are powered with a direct current during the circulation of said second electrolyte (8) for a preset second charge time.

The electrochemical regeneration of lead and alkaline battery cells during which, after the treatment of the battery by some of the regeneration additives on the basis of an aqueous solution of hydrogen peroxide and after the basic charging, they are alternately or intermittently charged and discharged. Above the limit located above the level of the full charge it is charged with a current of 1.1 % - 4% and discharged with a current of 0% - 5% related to the nominal value of the capacity of the cell or storage battery, or else the charging is carried out in two phases or by a constant current. Under the limit located below the level of the permitted discharging it is discharged with a current of 1 % to 4% and subsequently charged with a current of 3% - 10% related to the value of the capacity of the battery to a decrease in the voltage to 1.6 V of the cell or any of the battery's cells. Then the battery supplies 10% - 15% of its nominal capacity and this entire procedure is repeated 2 - 5 times. The regenerative agent contains, for each liter of aqueous solution 40% of hydrogen peroxide, 1 ml to 70 ml of sulfuric acid with a density of 1 to 1.32 g.cm-3, 0.1 g to 10 30 g of saccharides in solids and/or aldehydes or their derivatives, 0.1 g to 10 g of sodium and/or potassium bicarbonate and/or at least one hydroxide from the group of alkali metal hydroxides in solids, or else a mixture containing 0.1 g to 10 g of peroxoborate or tetraborate or sodium pyrophosphate in solids and also containing 0.1 g to 20 g, with an advantage 0.5 g to 2 g, of bisodium dinaphtylmethane disulfonic acid salt.
摘要:
The formation efficiency of pasted positive plates of a lead-acid battery is greatly enhanced by providing in situ a layer of lead dioxide (PbO₂) on the pasted plate surfaces prior to formation. The PbO₂ layer is preferably formed by treating the surfaces of the plates with an ozone-enriched gas to convert a portion of the poorly conductive positive active precursor material (nPbO·PbSO₄) to electrically conductive PbO₂. In subsequent electrochemical formation of the plates, the total formation charge can be reduced significantly while obtaining more complete conversion of the paste to positive active material. The method also provides an effective substitute for conventional curing of pasted positive plates.

摘要:
A basket of plastic material for the processing of the plates for dry-charge batteries. The basket is used in the electrochemical treatment of the plates for drycharge batteries and it consists of two identical elements (10, 20) being joined together by means offour segments (3, 4, 5, 6) being perpendicular to the gilled surfaces, said elements being joined together on corresponding shaped profiles by means of a screw-and-slot type junction. Each element (10, 20) is provided in its lower part with a small horizontal bar being parallel to the surface of the gills and slightly removed from them which functions as a lower support for the plates. The screw-and-slot type junction allows the adjustment of the opening between the two elements (10, 20) according to the dimensions of the plates being treated.
