Abstract
The present invention discloses production process of plate slab lattice for lead accumulator with non-metal material as skeleton. The non-metal material may be ABS plastics, glass fibre cloth, fibre felt, foamed polyurethane or other porous non-metal material. The present invention features its metallization process of non-metal material, which makes the non-metal material capable of being lead-plated chemically and directly without pre-plating transition layer of metal Cu or Ni in the production of plate slab lattice. The present invention opens a new way for increasing capacity of unit lead accumulator weight and raising utilization of active matter.
Description
Invented a kind of manufacturing technology of lead acid batteries electrode plate grid, it belongs to the technical field of lead acid accumulator, specifically belongs to the lead acid batteries electrode plate grid manufacturing technology that improves lead acid accumulator gravimetric specific energy and active material utilization.
Lead acid accumulator is with regard to its basic structure, and particularly its electrode manufacturing technology is still at present and continues to use old casting grid autofrettage, and the weight of this electrode plate grid will account for nearly 1/2 of entire electrode plate weight usually.Make in this way in the casting cycle of grid pollution also very serious to environment, the electrode of grid preparation thus, its real surface is long-pending often very little, and the utilance of active material also just can not get giving full play to, generally all below 40%.If again the influence of factors such as electrolyte solution is also taken into account in the lump, so existing lead acid accumulator be it seems with regard to its actual gravimetric specific energy that can reach, all is very low usually, and can not satisfies the needs of high power charging-discharging.Particularly easily generating again after overdischarge is shelved does not have electroactive sulfate, causes charging ability to descend.
The objective of the invention is can reduce raw-material consumption, reduce pollution environment in order to provide a kind of, satisfy battery high power charging-discharging characteristic needs, and can improve the manufacture method of the electrode plate grid of cell active materials utilization ratio and gravimetric specific energy thereof.
Technical scheme of the present invention is to adopt the skeleton of porous non-metallic material as grid, its nonmetallic materials can be polyurethane foamed plastics, also can be glass fabric and fibrofelt, after surface treatment, directly implement electroless lead plating, and then the lead plating thickening, just can make the nonmetallic materials metallization, form conductive battery lead plate with three-dimensional structure.Directly implementing in the solution of electroless lead plating, having one or more organic acid or acylates that can form stable comple, as nitrilotriacetic acid, citric acid or their ammonium salt, sodium salt and EDTA etc. with two valency lead ions; In addition, also need there be one or more can make the plumbous reduction reaction that takes place of two valencys in the solution, impel its reducing agent that can directly on nonmetal basal body, reduce existence, as titanium trichloride etc.On nonmetal skeleton, can implement the direct chemical lead plating, and excessive coating in the middle of needn't doing by other metals again, this is for as particularly important the electrode plate grid of lead acid accumulator, and it always exists for the corrosion of grid because the electrolyte of lead acid accumulator is strong acid H2SO4.If other metals of plating are made intermediate deposit, as copper or nickel etc., then, pollute because corrosion reaction will have a large amount of copper or nickel ion to dissolve in the electrolyte, poison electrode, so that electrode failure.
