Description
Technical field
Novel titanium or the titanium alloy collector that relates to a kind of lead-acid battery of present technique belongs to field of chemical engineering.Be expected to be applied to the lead-acid battery in fields such as electric motor car, electric tool, pulse emission and military project.
Background technology
The energy is the basis of human society survival and development, has represented the course of development in science and technology to the utilization of electric energy from the natural mineral reserve energy.Modern age; The last century quick development of human society particularly; Make the human resource consumption sharply increase; Causing with the oil is main being becoming tight traditional fossil energy day, and causes air pollution serious all the more, seek sustainable development approach, protect national resource and natural environment becomes the serious challenge of 21 century.Electric energy has become the energy of the indispensable a kind of cleaning of human society, and any other utilization of resources generally all must be used electric energy, and battery/capacitance technology is all used in the storage of electric energy, conversion, conveying.
Electric automobile (comprising pure electric vehicle and hybrid electric vehicle HEV) is pollution-free, use cost is low and be expected to the tuning network system paddy electricity at night, becomes the development trend of present research focus and future transportation instrument.Lead-acid battery application promise in clinical practice is arranged, but its specific energy shortcoming low, that cycle life is short has restricted its application in electric motor car at present because of characteristics such as its raw material resources are abundant, cheap, preparation, service procedure maturation and fail safe are good in electric motor car.
Lead accumulator is compared with lithium ion battery, and energy density is low, and its reason is that the lead or the lead alloy that are used for the battery lead plate collector are more thick and heavy.Titanium or titanium alloy with density is less are made the mass ratio that the afflux physical efficiency improves the battery lead plate active material, and then improve the battery specific energy.Yet it is loose that the lead base active material combines with titanium or titanium alloy sheet, phenomenon such as in the battery cyclic process, is prone to dry linting take place, come off, and causes battery life relatively poor.
Compare with common tabular or paper tinsel shape collector, cellular or draw in the net collector and have higher specific area, thereby can better must contact with active material.In addition, lead plaster has the characteristic of autoadhesion, and the cellular collector can make the lead plaster that is coated in the two sides be in contact with one another, thereby obtains better bond properties, makes battery obtain cycle life preferably.
Summary of the invention
The purpose of the utility model provides a kind of titanium or titanium alloy collector of carbonaceous lead-acid battery, and the duct of through electrode plate front and back is arranged on this collector, can improve the specific energy of lead-acid battery and recycle the life-span.
The technical scheme of the utility model is following: a kind of lead-acid battery grid, it is characterized in that this grid 1 is made up of collector electrode 2 and barrier 3, and collector electrode is connected conduct charges with external circuit, two barrier 3 clamping a slice collector electrodes 2.The thickness of grid 1 is at 0.5～8mm.Have collector electrode to connect duct 4 on the collector electrode 2, hole shape can be circle, ellipse, polygon, star or their combination, and the cross-sectional area in each duct is 0.25～100mm
2, pitch of holes is 1～20mm, thickness is 0.04～2mm.Have barrier to connect duct 5 on the barrier 3, hole shape can be circle, ellipse, polygon, star or their combination, and the cross-sectional area in each duct is 1～1000mm
2, pitch of holes is 1～20mm, thickness is 0.2～4mm.Collector electrode 2 is titanium, tantalum or their alloy with barrier 3, and it is shaped as paper tinsel, strip or netted, and the surface can have TiOx or TaOx to modify film.In addition, barrier 3 is polymethylpentene, polyethylene, polypropylene, polybutene, nylon, polystyrene, polyvinyl chloride, polyvinylidene chloride, rubber or silicon rubber, their composite material, or conductive plastics.
The collector advantage that the utility model provides is: make lead-acid battery have more high-energy-density, long-life advantage.Titanium or titanium alloy collector light weight make the shared mass ratio of battery lead plate active material improve, thereby obtain higher specific energy.Loose structure on the collector makes the lead plaster be coated in the two sides be in contact with one another, and bondingly closely suppressed the generation of dry linting, active material obscission, improved the life-span.
