Abstract
The case of storage battery is square. Plastic is used to substitute metal. Two to ten evenly divided chambers are in the case, the negative frame is stereoscopic nets by metal cutting and stretching, while positive frame is composite net of cutting and stretching net and foam nickel. The terminals and lead-out wires are connected by cold welding thus to simplify the technology and reduce the cost of producing high-capacity storage battery.
Description
The present invention relates to storage battery, belong to metal hydride-ickel accumulator group technology especially.
People pay close attention to day by day to urban air-quality and the crisis of earth petroleum resources; the protection environment; the energy savings cry grows to even greater heights; impel people to tap a new source of energy; wherein be power with the storage battery; greatly developing electric motor car is one of main direction of exploitation; and the key of electric motor car is a battery technology; metal hydride-ickel accumulator has very big capacitance; very high gravimetric specific energy; long useful life; advantage such as pollution-free has been adopted by various countries; and on low capacity, obtain practical application; but because the manufacturing issue of electrode; concerning big capacity, fail practicality; Chinese patent CN1086051A nickel-hydride accumulator for large capacity electric vehicle; the electrode manufacturing method that has tree root shape currect collecting net is disclosed; assemble large-capacity battery with the starting of solution electric motor car and the new forms of energy of traction with this electrode; but because it is the single storage battery of box hat, negative plate adopts corrosion plated metal plane net or nickel foam skeleton, manufacturing cost height in addition; complex process has limited its use.
The purpose of this invention is to provide a kind of square metal hydride ickel accumulator group.
The present invention realizes by following technical scheme, it includes shell, positive and negative electrode group, battery cover, electrode diaphragm, cell terminal, vent plug, its structural feature is that shell is a square, in be provided with 2-10 and wait lattice, the positive and negative electrode skeleton is netted shape, and this is netted is cut to draw by metal and form, and wherein positive pole is to draw in the net and the compound skeleton of nickel foam to cut.
The material of shell is plastics.
The material of positive and negative electrode skeleton is nickel, copper product.
The present invention is owing to adopt storage battery, and shell replaces box hat by plastics, and it is netted that the skeleton of negative pole adopts copper to cut to pull into, positive pole draws nickel screen and the compound skeleton of nickel foam to cut, and has reduced cost, has alleviated weight, good conductivity can be carried out heavy-current discharge, and discharge-rate can reach 20C.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is that cutting of electrode skeleton drawn in the net.
Fig. 3 is the pole plate skeleton that is welded into.
Fig. 4 is a battery pack different multiplying discharge curve of the present invention.
The invention will be further described below with reference to accompanying drawing embodiment.
Among Fig. 1, battery-pack exterior casing 1 is made by ABS plastic, in 10 lattices are arranged.Both positive and negative polarity group 2, cell lid 3, pole nut 4, battery anode post 5, cell unidirectional valve 6, cell pole 7, jumper 8, battery pack cover plate 9, battery pack negative terminal 10, pole plate lead-out wire and binding post cold welding tie point 11.
Among Fig. 2,3, the positive and negative electrode skeleton is netted 12, when negative plate is made, is that 0.1 millimeter Copper Foil is cut earlier and pulled into nettedly by setting size, thickness, forms stereoscopic graticule, cuts machine drawing by special equipment and is made.Weld lead-out wire 13 on the net, the skeleton that is welded with lead-out wire is placed in the mould, be placed on drying in the baking oven after the cream compacting with the hydrogen-storage alloy powder furnishing that mediation is good in advance, be put in the press again and pressurize.When positive plate is made, be that 0.1 millimeter nickel foil is cut and pulled into nettedly, weld lead-out wire on the net, by setting size cutting porous nickel mesh, be placed on the mould pressurization, pressure 10kg/cm again by setting size, thickness
2, put oven drying after the compound compacting with hickelous nydroxide, be placed in the press again and pressurize.The mode in succession of electrode outlet line and binding post adopts cold welding to be connected, and method is simple, helps producing in batches.
Among Fig. 4, the operating characteristic of battery, the magnitude of voltage when ordinate is represented to discharge, the battery capacity when abscissa is represented to discharge (ampere, hour).C represents battery capacity, as 12 ampere-hours, and 0.1C--0.1 * 12=1.2 Ampere currents discharge, 0.5C--0.5 * 12=6.0 Ampere currents discharge.Optionally on the curve just determine a bit it presently to put on the position, emit capacity and be how many times that its magnitude of voltage is for how high.This figure illustrates that this battery discharge voltage is steady, can heavy-current discharge, and capacity attenuation is few during discharge.Excellent performance of the present invention, with other battery ratio, voltage slope is very little, and internal resistance is low.
