The utility model adopts two kinds of fibers to be mixed and made into active matrix 3, be because Plumbous fiber can increase the surface area of active material, and the utilization rate of active material is obtained Improve, specific energy increases. Two kinds of fibers are mixed the similar nonwoven of rear employing copy paper Mode, be made into fibrofelt or fiber cloth structure, can make between the fiber can shape Become many holes, utilize the capillarity principle, when becoming the stream reaction, can Guarantee that sufficient acid flows into, and carries out reaction smoothly.
When making active matrix 3, can adopt two kinds of rear bunchys of fibers mixing more than 1 Make, namely when adopting single fiber to manufacture active matrix 3, guarantee various fibres Dimension can keep uniform mixed proportion, namely in identical unit are, contains The ratio of various fibers is identical. Manufacture active matrix 3 when adopting the plurality of fibers bunchy The time, this a branch of composite fibre both can adopt fiber of the same race, also can adopt by a regulation The composite fibre that ratio is mixed, but generally speaking, if the fiber number of bunchy When more, preferably adopt by the mixed fiber bunchy of certainty ratio and manufacture active matrix 3. The active matrix 3 that adopts said method to make has the structure of similar felt or cloth. When manufacturing active matrix 3, have more in order to make the polar plate of lead acid storage battery of making Good intensity and afflux electric conductivity also can be taked to make the metal fiber many Hole felted, place at this felt and above-mentioned matrix interval then, gets final product shape after light pressure Become to have the active matrix 3 of better intensity and afflux electric conductivity.
The composite fibre that the utility model uses mainly by a certain proportion of plumbous fiber and The metal fiber consists of. For increasing its afflux electric conductivity and improving lead-acid accumulator The intensity of plate plate also can add fiber and the impregnating agent of some other kinds. Plumbous fine Peacekeeping metal fiber is main body, in the situation that does not add other any fiber, namely Can be made into polar plate of lead acid storage battery of the present invention.
Plumbous fiber accounts for the 60-90% of plumbous fiber and metal total weight of fiber, and table Face is coated with the cadmium that accounts for itself weight 1-5%. After this lead fiber is made active matrix, And when doing positive plate, the top layer is β-PbO2Lattice; If when making negative plate, The top layer still is pure lead. This lead fiber is after making polar plate of lead acid storage battery, and is logical at warp When reaction electricity, every plumbous fiber under the catalytic action of the cadmium of plated surface, can Form β-PbO on the positive plate2Lattice, and by the surface to Deep Development, forming at last core is pure lead, and the top layer is β-PbO2Crystal lattice state. When discharge, β-the PbO on top layer2Form electric charge with acid reaction, the pure plumbous part of core then plays Delivered charge and become the passage of electric current. The metal fiber accounts for plumbous fiber and metal The 10-40% of total weight of fiber, and the cadmium that accounts for its this weight 1-5% can be plated in the surface. After it makes polar plate of lead acid storage battery, form on the surface of doing positive plate β-PbO2Lattice; When making negative plate, the surface is pure lead, and its inside is protected all the time Hold original alloy state.
Core content of the present utility model namely is to adopt certain with two kinds of above-mentioned fibers Ratio is mixed and is made into polar plate of lead acid storage battery. Because metal fiber itself is strong Degree is high, and corrosion resistance, has simultaneously preferably electric conductivity, with plumbous fiber After the mixing, fusion pressure goes out afflux conduction rib again, can satisfy strong in using of pole plate The performance that degree requires and afflux conducts electricity. So also can prevent in pole plate breakage and the battery Section's short circuit. Plumbous fiber mainly has been the effect that produces electric charge, and metal fiber master If play the afflux conduction and support whole pole plate. Also have in the metal fiber Contain a small amount of cadmium, two kinds of fibroplastic positive plate surfaces are kept β-PbO2Lattice makes pole plate keep high accumulate state. Briefly, adopting lead After fiber and metal fiber are made polar plate of lead acid storage battery, because these two kinds of fibers The surface is coated with the cadmium about 1-5%, therefore when the energising reaction, leads to the direct current positive pole The surface of one group of polar plate of lead acid storage battery under the catalytic action of surperficial cadmium plating, form β-PbO2Lattice. And in the use afterwards, in continuous charge and discharge process, Then be under the catalytic action by the cadmium that contains in the metal fiber, begun in plumbous fiber top layer Keep eventually β-PbO2Lattice. Because β-PbO2Microcosmic surface long-pending than α-PbO2Big nearly 20 times, therefore, form β-PbO2The reserve of electricity of lattice is far longer than α-PbO2Lattice, and be overdisharged at nearly 0 o'clock, still can be just after charging The normal use. In the present invention simultaneously, β-PbO2In plumbous fiber top layer and the reaction of metal fiber surface direct-electrifying, therefore connect very tight, be difficult for falling down, and these two kinds of fibrous insides keep pure lead or metal state, therefore the vibration that produces in the time of can standing the charging of heavy current pulse formula, and β-PbO2Do not belong to the isomorphous with sulfuric acid, the lead sulfate that generates after the discharge also just can't stop plumbous fiber top layer to the β-PbO of deep layer not at these two kinds of fiber surface tuberculosis Cheng Jing2Participate in reaction. Therefore exist In the discharge process, can keep for a long time High-current output. Another work of cadmium plating With being, the present invention will adopt the spark discharge technology after active matrix 3 is shaped, Make little the melting together of overlapped points of the various fibers in the composite fibre, so not only make When becoming the stream reaction, the reliable afflux conductive network of the inner formation of whole pole plate, Can also further strengthen the linking intensity between the various fibers in the whole pole plate simultaneously, Increase the service life of pole plate. And adopt the spark discharge technology, need plumbous fiber Having oxide layer with the metal fiber surface just can carry out. And after cadmium plating, cadmium namely Can replace oxide layer, make the spark discharge technology accomplished.
Contain the cadmium that accounts for its gross weight 0.5-5% in the metal fiber, the antimony of 1-7% Lead with 87-98.5%. Adopt metal fiber that above-mentioned prescription makes mainly general Use in the logical battery, and cost is lower.
Another metal of metal fiber is by 0.1-in the utility model 0.5% silver, the calcium of 0.08-0.5%, the cadmium of 0.5-5% and the lead of 94-99.32% Form. The metal fiber that adopts this prescription to make has preferably corrosion resistance, Also can improve the service life of battery. But manufacturing cost is higher, and because Add silver and can reduce the overpotential of hydrogen and oxygen, so be directed at the damage of electrolyte when using Loss-rate is bigger.
Satisfying other fine fibres that comprises also two of indication kinds of fibers in utility model Dimension. Microfibre is made of carbon fiber and other organic chemistry fiber. Add The main purpose of carbon fiber is to remedy metal fiber afflux electric conductivity not Foot. Especially within the limits prescribed, the metal fiber accounts for the less feelings of weight ratio Under the condition, when above afflux conductive effect is bad, add a certain amount of carbon fiber neither Obviously gain in weight, can play again good afflux conductive effect. Carbon fiber Addition be plumbous fiber and metal fibre weight and 1-5 ‰. In addition all right Add the organic chemistry fiber, refer to that mainly acrylic fiber etc. has acid corrosion-resistant and has The organic chemistry fiber of good pull resistance. Mainly in order to strengthen whole pole plate Intensity adds above-mentioned organic chemistry fiber, can produce the bundle of similar rope or net The bundle effect makes various fibers form integral body solidly.
