Description
The invention belongs to technical field of electrochemistry, is to adopt carbon one carbon composite to make battery terminal, to replace traditional metal electrode.
Along with world petroleum resource constantly reduces, having dropped into the substantial contribution development abroad is the vehicles of power with the novel energy.Particularly China is populous,, the petroleum resources poorness does not possess the condition of universal automobile.Therefore greatly develop the vehicles that novel energy is a power, significant.
From the development abroad situation, ancient storage battery still has important function.The AM General utility companies has developed 200 kilometers the storage battery automobile of can travelling after a kind of once charging.From ordinary circumstance,, but after the repeated charge 400 times, then have the strength of competing mutually and put goods on the market with automobile at present if travel 500 kilometers after reaching once charging.Certainly along with petroleum resources reduce, oil price improves, and this novel energy is the vehicles advantage of power, with increasing.W.Barcus " Gotes Engerg Product Battery Application Manual " (1980) for example.Series of advantages such as this is that powered vehicle has use cost low with the storage battery, free from environmental pollution, easy to maintenance.It is " specific energy " that but the subject matter that limits its use is the weight of storage battery, leading indicator.At present the used accumulator quality specific energy of battery vehicle only has 15～30 watts hours/kilogram, if bring up to 150～200 watts hours/kilogram, higher utility is arranged then.
For general storage battery, specific energy and useful life are two vital parameters.Because battery adopts acidity or alkaline solution, these solution have strong corrosivity to metal electrode, must the big and heavy battery of preparation in order to increase the service life.
In order to overcome above-mentioned deficiency, the objective of the invention is to adopt the carbon one carbon composite manufacturing of carbon fiber and enhancing thereof in light weight, good corrosion resistance, the life-span is long, and reserve of electricity is big, the battery terminal that intensity is high.
As everyone knows, carbon fiber is a kind of new engineering material, uses at aerospace field widely.Be characterized in light weight, the intensity height has satisfactory electrical conductivity and corrosion resistance.Particularly utilize carbon fiber reinforced " carbon one carbon " composite material to can be described as best electrode material.It is in light weight to use this material to make the battery terminal of triangle honeycomb shape, and reserve of electricity is big, good corrosion resistance, and the life-span is long.
Storage battery is also referred to as secondary cell, mainly contains acid and alkaline two kinds.Because the acid battery raw material are cheap, the source is abundant, and production technology is simple, cell voltage height, series of advantages such as internal resistance is little, and electrical property is reliable, the present acid battery that all adopts more than 95%.
The present invention selects " brown lead oxide one zinc " acid battery for use, this cell voltage height, and power-carrying can reach 300 watts hours/kilograms.Carbon fiber is zinc-plated to be made because negative pole adopts.Can be arranged higher useful life.The anodal lead dioxide electrode that adopts routine, and the cellular pole plate of positive triangle that uses carbon one carbon composite to make have bigger reserve of electricity, and simultaneously, " carbon one carbon " composite material battery electrode also can be used on " brown lead oxide one lead " storage battery.The power-carrying of " brown lead oxide one zinc " battery electrode can reach 300 watts hours/kilograms, if utilance reaches 50%, practical specific energy will reach 150 watts hours/kilograms.This battery has higher using value, compare with the lead accumulator of present use, weight saving 4/5ths.Can be used on the vehicles.
Carbon one C-C composite electrode battery as shown in Figure 1, by positive plate (5), negative plate (3), dividing plate (4), stillpot (6), bus-bar (1) and airtight container (2) are formed.Generate brown lead oxide PbO on the positive plate of charging back
2, negative plate then generates zinc Z
nDuring discharge, the brown lead oxide reaction on the positive plate generates lead sulfate PbSO
4, zinc then generates zinc sulfate Z on the negative plate
nSO
4Its cell reaction is as follows:
The standard electrode potential of zinc is-0.763 volt.The brown lead oxide standard electrode potential is 2.448 volts for+1.685 volts of these battery standard voltages.As calculated, this battery power-carrying can reach 300 watts hours/kilograms, and utilance is 50% o'clock, and then the actual mass specific energy can reach 150 watt-hour/kilograms.
Key technology of the present invention is the positive plate of carbon fiber reinforced triangle honeycomb, just the brown lead oxide pole plate.Preparation technology's flow process as shown in Figure 2.At first will prepare mould, mould as shown in Figure 3.Mould is made by tetrafluoroethene, and wiring gap (7) is arranged above.The degree of depth in space is equivalent to the thickness of pole plate, and width and geometry also can according to circumstances change.The present invention adopts equilateral triangle, and reason is that structural stability is good, and wiring is convenient.Also can adopt garden shape, shapes such as hexagon.
Second step was that wiring is solidified, select relevant resin matrix for use after, can be according to the formulated glue, preparing can be with the carbon fiber impregnation behind the glue, airing behind the impregnation, treat solvent evaporates after, can be distributed into curing in the mould wiring gap with latex bonded fibre by wire laying mode.Curing and demolding is then made the cellular carbon fibre reinforced composite of triangle.
Honeycomb after the curing is high temperature sintering under inert atmosphere, impregnation repeatedly as required, sintering carbonization.Until making " carbon one carbon " cellular battery electrode of composite material equilateral triangle.
This battery electrode is the brown lead oxide positive plate, and through the lead plaster that is coated with of routine, pressing plate drenches acid, and drying such as changes at the pole plate (5) that technology can be made into " brown lead oxide one zinc " storage battery.
Negative plate (3) is shown in figure-4.By cylinder manifold (8), pole (9), carbon fiber electrode (10), lower carriage (11), glass cloth interlayer (12) is formed.Cylinder manifold (8), pole (9), lower carriage (11) is formed a framework and is played supporting carbon fiber electrode (10).Carbon fiber electrode can be fixed on cylinder manifold (8) and the support (11) as required.Use glass cloth interlayer (12) that carbon fiber electrode is wrapped, play and isolate and protective effect.
Negative plate (3) can plate the zinc of constant weight as required, and same positive plate (5) is combined, and adds the sulfuric acid cell solution, forms " carbon one carbon composite brown lead oxide one zinc " storage battery.
Advantage of the present invention is to use carbon fiber reinforced carbon one carbon composite to make the acid battery positive plate of triangle honeycomb.Directly use carbon fiber to make negative plate simultaneously.This material and lightweight construction, the intensity height, good corrosion resistance, the storage electric flux is big, long service life.Process is simple simultaneously, can be used as novel power device and is used for vehicles storage battery automobile.
