Description
Technical field
The present invention relates to storage battery, especially relate to the lead plaster that accumulator plate is used.
Background technology
On January 3rd, 2009, the Ministry of Science and Technology, the Ministry of Finance issued " financial aid capital management Tentative Measures are promoted in the demonstration of energy-conservation and new-energy automobile ", and at 13 provincial capital's pilot conversions with Public Service Field New-energy electric vehicles such as public transport, taxi, public affair, environmental sanitation and postal services.Make the research and development application of electric automobile enter climax.The performance of the heart of electric automobile---battery is to the development decisive role of electric automobile, storage battery operation parameter on electric automobile has bigger difference with the electric bicycle ratio, the electric automobile starting current is big, be generally 2 multiplying powers of battery capacity, the discharge voltage limiting value is uncertain, this just requires batteries of electric automobile to have the good advantage of recovery capability after the ability of high-multiplying power discharge and the overdischarge, has only with novel lead paste formula and could satisfy new requirement.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of storage battery diachylum formula for electric vehicle, and this lead paste formula has recovery capability after the ability of high-multiplying power discharge and the overdischarge, can adapt to the startup of electric automobile, the requirement of travelling.
The present invention is achieved through the following technical solutions:
Storage battery diachylum formula for electric vehicle, chemical component weight percentage is: oxidizability is 70%～85% Tianjin, island formula lead powder 70%～80%, brown lead oxide 2%～10%, chemical fibre 0.1%～0.15%, stannous sulfate 0.01%～1%, rare earth element 0.01%～1%, water 10%～15%, and solution concentration is 40～50% sulfuric acid 4%～10%.
The further improvement project of the present invention is that described rare earth element is a kind of or two or more mixtures among light rare earth element Sc, La, Ce, Pr, Nd, Pm, Sm, the Eu.The weight percentage of each element: Sc10%～20%, La10%～20%, Ce20%～50%, Pr1%～5%, Nd1%～5%, Pm1%～5%, Sm1%～5%, Eu1%～5% in the light rare earth element mixture.The product that it is buied for market.
The further improvement project of the present invention is, the length of described chemical fibre is the 1-2.5 millimeter, and it is acrylic, terylene or polyamide fibre.
The preparation method of storage battery diachylum formula for electric vehicle comprises the following steps:
(1) by the described proportioning of claim 1 chemical fibre and water are mixed, mix brown lead oxide, stannous sulfate, light rare earth element mixture three standby simultaneously;
(2) 50% of the lead powder total weight after will weighing by the described proportioning of claim 1 pour in the paste mixing machine, in paste mixing machine, add brown lead oxide, stannous sulfate, light rare earth element mixture that step (1) mixes again, in paste mixing machine, pour second half lead powder then into, the start dry mixing makes built-in temperature rise to 45 ℃, add the chemical fibre that step (1) mixes then, add remaining 10% water of step (1) again, 5min-10min is stirred in start, makes the preliminary oxidation of lead powder; Then,
(3) in the time of 12-15min, under stirring, by the described proportioning of claim 1 sulfuric acid is slowly added in the paste mixing machine, and constantly stir the interior mixture of paste mixing machine, make it full and uniform, when temperature in the paste mixing machine reaches 65 ℃, open cooling water temperature;
(4) sulfuric acid adds back continuation stirring, is the finished product lead plaster below 45 ℃ when temperature in the paste mixing machine drops to.
The present invention improves lead plaster needle penetration owing to added stannous sulfate, penetrates effect when having increased the lead plaster smear, has improved the pole plate mechanical strength, delays positive material.The adding of light rare earth element has improved the contact effect of grid with active material, has reduced the internal resistance of cell, makes battery have good heavy-current discharge performance.Add a spot of brown lead oxide, make positive pole before changing into, set up skeleton, reduced the groove pressure that battery changes into, effectively raise forming current efficient, shortened the time of changing into, saved cost.The present invention can use the brown lead oxide of recovery to do additive, has environmental benefit preferably.
Adopt lead plaster of the present invention to be coated in the storage battery of making behind the positive grid, both had higher initial capacity, the average life span that can prolong storage battery also can prevent the premature capacity loss of storage battery more than 50% effectively again.The present invention has satisfied the needs of new-energy automobile industrial development.
