Description
Technical field:
The utility model relates to a kind of high strength fibre with metallic cover, and especially a kind of continuous composite wire with metallic cover is applicable to the coat of metal that coats even compact on nonmetallic core wire material surface.Belong to metal-composite material processing technique field.
Background technology:
The course in century more than one has been experienced in traditional lead-acid battery manufacturing, but traditional lead-acid battery technology improves energy content of battery density to a nearly step its limitation is arranged.Usually in order to improve the energy weight/power ratio performance (specific energy density) of battery, in the design of battery, to reduce non-capacity contribution such as slab lattice thickness and connector weight partly as far as possible.Yet, consider the battery applications classification, the course of processing of pole plate, battery recycle life-span and other some performance requirements, must adopt again to have certain thickness grid and connector.So by traditional lead-acid battery, its specific energy density is two factors that condition each other with recycling the life-span.Want to improve the energy density of battery simultaneously and recycle the life-span, adopt traditional cell manufacturing method to be difficult to realize.For solving this contradiction, on grid structural design and material, all done a lot of improvement in the past, comprising adopting new high strength and corrosion resistance lead alloy, grid is drawn in the net in forging and pressing or expand, lead-composite panel of plastic material grid, lead-technology such as glass fibre composite web grid.As United States Patent (USP) 4,091,183, United States Patent (USP) 4,110,241, United States Patent (USP) 4,279,977, United States Patent (USP) 5,462,109 or the like.Although these technology all have its advantage separately, these technology all are the specific energy at battery useful life and battery, have taked compromise method in the volumetric properties contrast.In disclosed technology at present, still do not have a kind of technology to provide and have high-energy-density simultaneously, the long-life, be fit to electric vehicle, in enormous quantities the battery of commercialization production.Early stage United States Patent (USP) 275,859 discloses a kind of apparatus and method of utilizing extruding-drawing mode metallic lead to be coated on the Telephone Cable wicking surface.But this apparatus and method do not relate to the requirement to the heart yearn material, are not suitable for coating the core of thin diameter simultaneously yet.United States Patent (USP) 2,963,739 disclose a kind of with glass fibre by motlten metal lead, make the compound (1) silk thread of metallic cover on the surface of glass fibre.But since fusion of lead surface tension height, the cause of dipping property difference, and the actual effect that adopts this motlten metal sheath to cover glass fibre is bad; The surface combination power of metallic lead coating layer and glass fibre heart yearn is very poor, can not keep metallic lead coating layer even compact, and is easy to break away from the glass fibre heart yearn.United States Patent (USP) 4,169,911 disclose a kind of diverse ways (electroplating chemical plating, vacuum moulding machine, ion sputtering) that passes through on conductive fiber (carbon fiber) surface, and metal or alloy is coated on carbon fiber surface and forms compound (1) silk thread.Yet disclosed this coating compound (1) silk thread only is applicable to conductive fiber (carbon fiber) core and is not suitable for non-conductive fiber, as glass fibre.As be applied in the lead-acid battery, if especially be applied in the positive pole of battery, its decay resistance has very big problem.United States Patent (USP) 4,658,632, United States Patent (USP) 5,010,637, United States Patent (USP) 6,027,822 provide the process technology of a kind of lead-glass fiber composite filament line.Also be by a kind of extruding-Hubbing method, make metallic lead be coated on the surface of glass fibre heart yearn and the compound (1) silk thread that forms.The process technology of this lead-glass fiber compound material is by the improvement to above-mentioned early stage United States Patent (USP) 275,859, is used for coating the core of thin diameter.Utilize this lead-glass fiber composite filament to be woven into net, and be processed into the grid of the special-purpose pole plate of lead accumulator, can have higher mechanical strength and corrosion resistance, be used to bipolarity horizontal battery (Electrosource Ltd) in recent years.Yet utilize the lead-glass fiber composite filament of this method processing, remaining in certain defective aspect the surface combination of metallic lead coating layer and glass fibre heart yearn, if with this compound (1) silk thread during as the collector of positive plate, especially recycle in the degree of depth, because what this metallic cover layer material adopted is pure lead, decay resistance and conductivity thereof all can not satisfy the conditional request that the battery degree of depth recycles.In sum, relating to the metallic cover high strength fibre in the disclosed patent at present, the compound (1) silk thread that especially coats the metal level of even compact on nonmetallic core wire material surface all has certain limitation.Therefore in the production of storage battery, especially in the manufacturing of lead acid accumulator, to improve the energy density of battery simultaneously and recycle the life-span, if adopt metallic cover high strength fibre establishment Web materials to replace traditional electrode plate grid, then must solve the problem of the adhesion difference that metal carbonyl coat and non-metallic fibers heart yearn surface exist on combination interface, particularly to solve decay resistance and electric conductivity, make it can satisfy the conditional request that battery recycles in the degree of depth.
Summary of the invention:
