Abstract
The invention provides a super-pore stretching-mesh lead-acid battery grid which is formed by rolling lead metal or lead alloy, and comprises a confluence edge and also comprises ribs made by a stretching process, and the ribs are staggered to form meshes which are uniformly arranged. The purpose of the invention is that the lead-acid battery gird is produced according to a super-pore stretching-mesh method, pore size of the lead-acid battery gird is greatly reduced, meanwhile, the sizes of the gird ribs are reduced, so that superficial are of the grid is substantially increased, the utilization rate of an active substance is greatly improved, thus specific energy and charging/discharging performance of a lead-acid battery are greatly improved, and the service life of the lead-acid battery is greatly prolonged.
Description
Technical field
The present invention relates to a kind of lead acid accumulator part, particularly a kind of cutting drawn in the net lead acid accumulator plate grid.
Background technology
At present, the grid of prior art lead acid accumulator adopts gravitation casting method, plumbous band tandem rolling development method and plumbous band punching method to produce substantially.Adopt the hole dimension of the lead acid accumulator plate grid that these methods produce large, be generally 6mm * 8mm; Grid rib size is thick, be generally 1mm * 1.5mm, make the surface area of prior art grid little, few with the contact area of active material, make the polar plate of lead acid storage battery that adopts prior art grid to produce, active material utilization is low, and the charge-discharge performance of battery is poor, specific energy is low, useful life is short, can not meet the needs of lead acid accumulator development.
Summary of the invention
The object of the invention is: the method that adopts extra small hole to cut to draw in the net is produced lead acid accumulator plate grid, significantly reduce the hole dimension of lead acid accumulator plate grid, reduce the size of grid rib simultaneously, with this, increase substantially the surface area of grid, active material utilization is significantly improved, thereby increase substantially specific energy, charge-discharge performance and the useful life of lead acid accumulator.
The object of the present invention is achieved like this:
Extra small hole is cut and is drawn in the net a lead acid accumulator plate grid, by lead metal or lead alloy, is rolled into, and comprises the limit of confluxing, and also comprises cutting drawing in the net the rib that technique makes; Described rib is staggered to form some equally distributed mesh.
Further, the Kong Changwei 0.5mm-3.5mm of described mesh.
Further, the Kong Kuanwei 0.5mm-3.5mm of described mesh.
Further, described slab lattice thickness is 0.1mm-3mm.
Further, the width of described grid rib is 0.2mm-1.5mm.
Further, described lead acid accumulator comprises all types of lead acid accumulators such as start type, power type, accumulation energy type, motor vehicle type, boats and ships type, railway type, military version, fixed.
Further, described lead metal comprises various lead and the lead alloys such as pure lead, terne metal, pewter, lead-calcium alloy, Pb-Ca-Sn-Al alloy, lead-antimony alloy, lead strontium alloy, plumbum rare earth alloy
During making, adopt lead metal or lead alloy to be rolled into the lead band of thickness 0.1mm-1.5mm, adopt again numerical control cutting net puller lead band to be cut to the extra small hole lead acid accumulator plate grid that pulls into hole dimension 0.5mm-3.5mm * 0.5mm-3.5mm, the width dimensions of grid rib is controlled at 0.2mm-1.5mm, makes the surface area ratio prior art grid of grid improve more than 5 times.
The invention has the beneficial effects as follows, owing to adopting above scheme, charging and discharging capabilities and the cycle life of lead acid accumulator increase substantially.Through test, adopt more than the discharge capability of lead acid accumulator of the present invention can reach 100C, can in 2 hours, complete 100% charging, deep discharge service life cycle surpasses 500 times, is the more than 5 times of prior art lead acid accumulator.The scope of application of the present invention is wide, goes for all types of lead-acid batteries.
