Abstract
The invention discloses a super battery negative plate which comprises a plate grid, wherein an electrode lug is arranged at the top of the plate grid; a lead paste coating is arranged on the surface of the plate grid, which is close to the electrode lug; and carbon paste coatings are respectively arranged on the other outer surfaces of the plate grid. The lead paste comprises the following components in percentage by weight: 1 percent of lead powder, 0.05-0.12 percent of chopped fiber, 0.4-2 percent of barium sulfate, 0.1-0.2 percent of humic acid, 0.08-0.2 percent of lignin, 0.2-0.5 percent of carbon black and the balance of deionized water; and the carbon paste comprises the following components in percentage by weight: 20-30 percent of activated carbon, 0.2-2.5 percent of acetylene black, 0.2-2.5 percent of polyfluortetraethylene and the balance of deionized water. The surface area ratio of the lead paste to the carbon paste occupying the negative plate is 6:(1-1):1. The invention has the benefits that: under the condition of no influencing the compression ratio of the battery, a carbon plate with a capacitance performance replaces the lead paste at the lower part of the negative plate so as to reduce the shock of heavy current during charging for the negative plate, prolong the service life of the battery and improve the specific power performance.
Description
Technical field
The present invention relates to lead acid accumulator, more specifically is a kind of superbattery negative plate.
Background technology
In recent years; Because of advantages such as lead-acid battery mature production technology, cheap, fail safe height have been widely used in electric bicycle; Application prospect is also being arranged aspect electric motor car, the hybrid electric vehicle, and this has higher requirement to the cycle life under its specific power and the high power discharge.
In August, 2009; The US President Barack Obama announces; Appropriate funds 2,400,000,000 dollars to support 48 project developments of the U.S. " battery of future generation and electric motor car " production; In these funds, have 6,680 ten thousand dollars of research and development of investing the novel lead-acid battery, wherein 3,250 ten thousand dollars are used to produce superbattery (Ultrabattery).
So-called plumbic acid " superbattery "; Be that evolving is exactly the high-specific-power of double electric layer capacitor, long-life advantage to be fused to " also interior " in the lead-acid battery with the parallelly connected use (can claim " also " outward) of ultracapacitor with lead-acid battery; When keeping " outside also " to improve power, extending battery life advantage; Can simplify circuit again, improve specific energy, and reduce total cost.Superbattery is being in the green energy resource of representative with electric bicycle and the electric automobile that starting, with producing huge economic benefit and social benefit.
In the recent period, all technology maturation, cheap lead-acid battery are combined with the ultracapacitor that has high-specific-power, have extended cycle life both at home and abroad in research.Australian CSIRO scholar just submitted the superbattery patent in 2004, and at first on periodical, reported the research work of superbattery in 2006.More domestic enterprises or research institution are also carrying out correlative study.It is the carbon slab that matrix has capacitive property with the lead base grid that the super battery plate structural design is generally the extra parallel connection of normal Pb negative plate.But this structural design is complicated, and cost is high, increases the welding difficulty simultaneously; Particularly under the situation that does not change the battery container size; Extra adding carbon slab, obviously the compression ratio of change normal battery influences battery performance; It is not obvious to make that finally battery performance improves, in addition with the lead-acid battery performance indistinction that does not add before the carbon slab.
Summary of the invention
The objective of the invention is: the heavy-current discharge performance that overcomes the lead acid accumulator existence that is applied at present in the electric motor car is poor; The sulfation problem; A kind of superbattery negative plate is provided under the situation that does not influence the standard cell compression ratio simultaneously; Improve negative plate and when heavy-current discharge, form irreversible sulfation, prolong battery cycle life.
The technical scheme that the present invention deals with problems is: a kind of superbattery negative plate, comprise grid, and lug is arranged at the grid top, scribbles the lead plaster coating near the grid appearance of lug, and all the other grid appearances scribble the carbon paste coating.
The weight percentages of components of said lead plaster: lead powder 1%, short fiber 0.05-0.12%, barium sulfate 0.4-2%, humic acid 0.1-0.2%, lignin 0.08-0.2%, carbon black 0.2-0.5%, surplus part is deionized water;
The components by weight of said carbon paste is: active carbon 20-30%, and acetylene black 0.2-2.5%, polytetrafluoroethylene 0.2-2.5%, surplus part is deionized water.
Said lead plaster and carbon paste account for the negative plate surface area ratio: lead plaster: carbon paste=6: 1-1: 1.
More specifically, said lead plaster and carbon paste account for negative plate surface area ratio optimum value and are: lead plaster: carbon paste=4: 1.
The weight percentages of components of said lead plaster: lead powder 1%, short fiber 0.07%, barium sulfate 0.8%, humic acid 0.15%, lignin 0.1%, carbon black 0.36%, surplus part is deionized water;
The components by weight of said carbon paste is: active carbon 24%, and acetylene black 0.5%, polytetrafluoroethylene 0.5%, surplus part is deionized water.
Said active carbon specific area is 1000-1800cm
2/ g, apparent density 0.3-0.5g/cm
3
Said short fiber can be polyacrylonitrile fibre, fibre length 4-6mm, diameter 7-13um.
The invention has the beneficial effects as follows: under the situation that does not influence the battery compression ratio; The carbon plate that will have capacitive property replaces the very easily lead plaster of sulfation of negative plate bottom; The impact of anticathode plate in the time of not only can reducing heavy-current discharge, extending battery life provides the high-specific-power performance simultaneously.
