Abstract
The invention discloses a high-permeability lead-acid battery cathode with high specific surface area, which comprises an electrode plate grid, and an active substance arranged in the grid meshes of the electrode plate grid in a filling manner, wherein the active substance comprises the following components in parts by weight: 1000 parts of lead powder, 20-30 parts of bismuth oxide, 10-30 parts of zinc oxide, 10-30 parts of calcium sulfate and 10-50 parts of carbon nanotubes. Due to the high surface area of the carbon nanotubes, the electrolyte on the cathode surface can easily permeate and can react with active ingredients, and the charging and discharging capability can be improved.
Description
Technical field
The invention belongs to lead accumulator technical field, particularly relate to battery cathode technology.
Background technology
At present for environmental protection object, replace conventional petroleum, the contour pollution power sources of coal, electric energy is more and more paid attention to and is applied.And lead acid accumulator is the major impetus source of current electric automobile, bicycle etc.But its reliability.Non-maintaining property, deep cycle battery capacity attenuation and corrosion resistance all have much room for improvement.Especially at present the lead acid accumulator made of terne metal traditional electrode is analysed oxygen and is suppressed not good due to grid corrosion distortion, active material liberation of hydrogen, easily to come off etc. to cause its life-span not long.
Summary of the invention
Goal of the invention: for above-mentioned existing Problems existing and deficiency, the object of this invention is to provide a kind of Thief zone high-specific surface area lead-acid battery cathode.
Technical scheme: for achieving the above object, the present invention is by the following technical solutions: a kind of Thief zone high-specific surface area lead-acid battery cathode, comprise electrode plate grid and be filled in the active material between electrode plate grid grid, described active material comprises following component: the carbon nano-tube of 1000 parts of lead powder, 20 ~ 30 parts of bismuth oxides, 10 ~ 30 parts of zinc oxide, 10 ~ 30 parts of calcium sulfate and 10 ~ 50 parts.
As preferably, described electrode plate grid is copper base lead-antimony-calcium alloy slab lattice.
Beneficial effect: compared with prior art, the present invention has the following advantages: relatively common lead ashbury metal battery grid have higher anticorrosive deformation nature, high specific gravity capacity, after repeatedly discharge and recharge deeper cavity, still have good battery capacity, therefore the life-span is longer; The high-specific surface area that the more important thing is due to carbon nano-tube makes the electrolyte of negative terminal surface more easily permeate to react with active component, improve its charging and discharging capabilities.
Embodiment
Below in conjunction with specific embodiment, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
Be substrate at copper and on copper, prepare the alloy-layer of lead-antimony-calcium, and finally making negative electrode grid.In 1000 parts of lead powder, add the carbon nano-tube of 25 parts of bismuth oxides, 10 parts of zinc oxide, 20 parts of calcium sulfate and 30 parts, mix, and lead plaster is formed in paste mixing machine, and by this lead plaster full-filling on above-mentioned negative electrode grid, eventually pass solidification and drying, obtain battery terminal negative pole plate.
Titanium or copper, as matrix, can reduce pole plate density, improve the gravimetric capacity of battery, and copper ion are free from side effects to electrolyte.Because the high-specific surface area of carbon nano-tube is active, negative pole is made to have more excellent electrolytic solution permeability.
Find that liberation of hydrogen of the present invention and oxygen evolution potential are increased significantly by doing cyclic voltammetry curve test to above-mentioned pole plate, there is higher overpotential, thus water electrolysis formation hydrogen and oxygen can be reduced, improve the stability of battery liquid.
Charging performance test is carried out to the battery that embodiment is made: charge and discharge cycles test is carried out in the degree of depth 8h electric discharge with 85%, 8h charging.The battery of embodiment 1 and 2, through 350 loop tests, still have the battery capacity of more than 86%, and the battery capacity of conventional accumulators has dropped to less than 72%, has needed to scrap.
Claims (2)
