Embodiment
An embodiment of the present invention product structure and manufacturing process are described as follows.
The preparation of a, positive and negative pole plate copper coin grid, bus-bar, polar biased post, end pole:
1, the ratio of the extremely positive and negative grid thickness of battery is 1.10-1.3: 1.0, and utmost point grid depth-width ratio is 0.7: 1.0; The perpendicular muscle of grid is 1.0: 0.8 with the ratio of the width of horizontal bar, and perpendicular muscle number is 1.0: 0.7 with the ratio of horizontal bar number; The thickness 0.1mm of grid, the grid grid strikes out rectangle, borrows to be pressed into the corresponding rectangle of quantity towards the surplus limit of grid and periphery makes progress into II shape, and peripheral II height is the thickness of grid.The plate ear of positive/negative plate places 2/5ths places of pole plate partial center distance, the wide 10-30mm of lug, high 10-30mm, in the high 8-20mm of lug position, to wide horizontal direction towards the hole of diameter 1mm more than 1.Plate railings of anode and cathode is pressed the electroplating technology plating then.Anodal copper coin grid silver-plated (Ag), thickness 0.5um, lead plating thickness 10 μ m again.The negative thick 0.6um of grid zinc-plated (Sn), lead plating again (Pb), thick 10 μ m.Grid periphery plastic-blasting material, the wide 1-3mm of plastic-blasting material, thick 0.5 μ m.
The preparation of b, conflux grate part:
The bus-bar effect be storage battery when discharge process, transfer chemical energy to electric energy.The electric energy of multi-disc pole plate compiles through bus-bar, powers to electrical appliance.During charging, be with external electric energy through bus-bar, be transferred to battery pole plates, electric energy is converted into chemical energy.The length and width of bus-bar, thickness are by the size of storage battery power, and how many polar plate numbers decides, through bus-bar one in parallel.Through positive and negative extreme pole, with electric current output or input.The voltage of whole storage battery is high and low be many by the cell batteries series connection, form less.Advanced storage battery is used through-wall welding for reducing resistance, and spot welding connects the polar biased post, with cell batteries series connection (but external latticing connecting mode is arranged).What of polar biased post are by how many decisions of Series Sheet accumulator body; The quantity of end pole is: monomer or whole storage battery have only positive and negative electrode (being the positive and negative utmost point), and the end pole is two.
The current density of copper is 8A/mm
2, overcurrent density is 10 times of above-mentioned current densities 25 ℃ of temperature and at 30min.Main physical performance because of copper: conductance is good, and thermal diffusivity is strong, the fusing point height, and resistivity is 1.7*10
-6Ω/cm, density is 8.99g/cm
3Because of copper has the drawback that produces kelvin effect, the diameter of copper conductor is during greater than 5mm, and current density reduces, and is not more than 5mm with copper coin grid thickness, need during greater than 5mm with many copper rods (or multiply copper stranded conductor).
The structure of bus-bar is a sheath copper, and because of the welding difficulty is big, so sheath copper, the volume of copper accounts for the volume about 3/5ths of bus-bar.All the other are lead alloy, the minimum 3mm of the thickness of bus-bar.
The fastening copper rod diameter of the company of wearing is not more than 4.8mm, and length is determined by the storage battery watt level; The thickness of polar biased post copper coin is not more than 5mm, widens the polar biased post in case of necessity; The copper rod diameter of end pole is not more than 5mm, adopts many copper stranded conductors in case of necessity.
The copper rod of the fastening pole plate of the company of wearing is zinc-plated, zinc-plated thick 0.6 μ m.Polar biased post copper coin is zinc-plated, and zinc-plated thickness 0.6 μ m is plumbous with the punching block casting then; The inclined to one side post in the two poles of the earth is worn the face of weld of wall contact, the thickness 0.5mm that casting is plumbous.
The copper core height of end pole and diameter are by the watt level decision of storage battery.Diameter is not less than 3mm, and the available copper post that is molded into, diameter are used the multiply copper stranded conductor during greater than 5mm.The copper core of end pole, zinc-plated thickness 0.6 μ m.Use die casting lead.The casting lead thickness of end pole top, bottom is not more than 2mm, and all the other positions are not more than 10um.
The general assembly of C, storage battery:
The general assembly of a, storage battery is with accumulator positive, negative plate, places the comb pattern of mould respectively, and the copper rod of the fastening pole plate of the company of wearing of preparation is worn along the lug hole, and lug is fastening.Polar biased post or end pole place comb pattern appropriate location, casting or welding alloy lead, and quality requirement does not have rosin joint, crackle, burr, want firmly, then at the side face and the high 10mm of the lug place of bus-bar, and the polar biased post is when the storage battery general assembly, and coating thickness 2 μ m plastics are anticorrosion.
Dividing plate between b, accumulator positive, negative plate is bored a hole with plastics, and porosity is not less than 90%, the thick 0.2mm of dividing plate base plate, the thickness 1.0mm of rib, total thickness 1.2mm.
C, storage battery total coating process flow process are once covered heat-sealing-air tight test-sealing end pole-perfusion electrolyte sulfuric acid-storage battery secondary lid heat-sealing-charging-accumulator property check for can-dress foam plate washer-storage battery that utmost point group welding-slotting dividing plate-high voltage detects insulation-through-wall welding between the storage battery positive and negative electrode-big current detecting quality of welding spot-silicon dioxide.
