Abstract
The invention relates to a storage battery plate additive, belonging to the field of low-temperature storage battery charge property improvement. To improve the low-temperature charge property of a power storage battery, a formula of a lead plaster additive for storage battery positive and negative plates is provided. When the conductivity of active substances is improved, the porosity and the strength of the active substances are also improved, so that the low-temperate charge acceptance capability of the storage battery is improved, and the circulation service life of the battery is prolonged. The formula is achieved by combining the following additives: conductive graphite fibers or conductive carbon fibers are added into the lead plaster, with the addition amount accounting for 0.05-0.08% of the weight of lead oxide so that the mechanical strength and the conductivity of lead plaster are improved; the following auxiliary materials in percentage by weight of lead powder are added: 0.2% of acetylene black, 0.03% of aquadag, 0.03-0.05% of gas phase silicon dioxide, 0.06-0.08% of red lead, and 10% of pure water; the materials are sufficiently stirred into suspension, and subsequently the suspension is added into the lead powder and is stirred.
Description
Technical field:
The present invention relates to a kind of accumulator plate additive, belong to and improve storage battery low temperature charging performance field.
Background technology:
Lead acid accumulator occurs that over more than hundred year, use field is more and more extensive, from automobile starting, and in recent years progressively to battery-operated motor cycle, electric automobile power battery future development.As new-energy automobile power battery, occur that many new problems need to solve.The client on the ground such as Hebei, Shandong, exactly electric four-wheel vehicle is parked in to open air in winter, due to winter temperature low, sometimes there are subzero 10 DEG C-18 DEG C, and existing power accumulator low temperature charging performance can not meet the demands, when concrete manifestation is exactly low temperature, charge full once filling, a few minutes voltage just rise to very high, current reduction, to very low, can fill electricity.But an electric discharge, voltage is just broken down, and electric current is also very little.Battery is removed, take the place that temperature is high and put 30 minutes (25 DEG C indoor), battery charge can fast rise, and battery can charge normal again.This is during due to low temperature, because cell active materials lead sulfate electric conductivity reduces, at the lead sulfate of grid Surface Creation densification, affects electric conductivity and causes.For addressing this problem, also there is people in winter low temperature, load onto heating plate to battery, a circuit is set by heating plate work when charging, can promote like this battery capacity.Heating plate at low temperatures the charging to battery and the course of travelling helpful, but this method danger is high, if adding thermal control goes wrong, likely battery is burnt out and causes fire, the method that these methods improve battery charge acceptance is all external method, cures the symptoms, not the disease, and increases much inconvenience to client, for this reason, in the urgent need to a kind of solution that improves battery low temperature charge acceptance at battery in manufacture process.
Summary of the invention:
In order to improve the low temperature charging performance of new-energy automobile power accumulator, invent a kind of accumulator plus-minus polar plate lead plaster additive formulations, in improving active material electric conductivity, improve porosity and the intensity of active material, thereby improve storage battery low temperature charge acceptance.Meanwhile, this formula can also improve the bond strength of active material and grid, improves the bond strength of lead plaster, prevent the softening and sulphation of active material, prevent the active material powder that collapses, thereby improve the low temperature charge acceptance of battery, the cycle life that extends battery.The present invention realizes by following additive combination:
1, strengthen mechanical strength and the conductivity of lead plaster, add in lead plaster with electrically conductive graphite fiber or conductive carbon fibre.Addition is pressed the 0.05-0.08% of lead oxide weight.
2, the addition manner of additive: add following auxiliary material by the percentage of lead powder weight: acetylene black 0.2%, aquadag 0.03%, aerosil 0.03-0.05%, red lead 0.06-0.08%, add pure water 10%, add in lead powder and stir again after fully stirring into suspension.
3, battery positive voltage formula: 75%-85% lead oxide 100kg, 3mm electrically conductive graphite fiber 0.05-0.08%, aerosil 0.03-0.05%, acetylene black 0.2-0.3%, aquadag 0.03-0.06%, red lead 0.6-0.8%.D1.4 sulfuric acid 9-10kg pure water 9-10kg.
