Description

A kind of Vehicular battery negative plate lead paste formula and preparation method thereof
Technical field
The present invention relates to vehicle battery, is a kind of Vehicular battery negative plate lead paste formula and preparation method thereof more specifically.
Background technology
Arrival along with the new forms of energy epoch, the discovery of motor vehicle (comprising hybrid power and pure electric power) is maked rapid progress, the power accumulator of electric motor car at present, become electric motor car industry and find the focus of paying close attention to, at present, the fail safe of lithium battery and cost performance do not obtain effectively solving and other chemical power sources effectively under the condition of civil nature, and lead acid accumulator becomes consumption maximum, the power source that practicality is the strongest.Meanwhile, the application mode of lead acid accumulator changes large electric current, powerful application mode into by standby and little electric current, the low power applications mode of routine, and it also faces the predicament that specific energy is low, the life-span is short in specification requirement.Current domestic raising Specific Energy of Lead Acid Storage Batteries common method low, that the life-span is short has: 1, attenuate electrode, improved electrode specific surface area, but production control quality cost is high, inefficiency; 2, in electrolyte, add soluble additive, improve the battery specific surface in early stage, but only improve capacity in early stage, can not continue to keep battery capacity; 3, improve concentration of electrolyte, but accelerate sulfation; 4, add conductive material, improve depth of discharge, but high cost.
Summary of the invention
The object of this invention is to provide a kind of Vehicular battery negative plate lead paste formula and preparation method thereof, have that specific energy is high, large current density power is strong, low temperature capacity is high and the lasting feature that circulates.
The present invention realizes in the following way: a kind of Vehicular battery negative plate lead paste formula and preparation method thereof, it is characterized in that, lead paste formula is: lead powder 100kg, short fiber 0.03-0.10kg, active carbon 1300-1700g, titanium dioxide 10g, bismuth oxide 20g, sodium carboxymethylcellulose 100-150g, polytetrafluoroethylene 200-300 g, electrically conductive graphite 200-250g, aerosil powder 100-150g, deionized water 10000-11000g, concentration are 1.30-1.40g/ cm 3the sulfuric acid 8000-9000ml of (25 ℃).
During preparation, first prepare the lead paste formula of formula components weight ratio.Sodium carboxymethylcellulose (CMC), ptfe emulsion (PTFE) and deionized water are made to finely dispersed emulsion by the quality of 1:2:5 than mix and blend, as dispersion, binding agent, use; Again lead powder, short fiber, active carbon, titanium dioxide, bismuth oxide, electrically conductive graphite, aerosil powder are mixed, at the uniform velocity stir 10-15 minute, and in 1-3 minute, add the even emulsion with sodium carboxymethylcellulose (CMC), ptfe emulsion (PTFE) and deionized water preparation, ceaselessly at the uniform velocity stir 10 minutes; By ready concentration, be 1.3-1.4g/cm 3the sulfuric acid of (25 ℃) proportional quantity slowly adds, and continues to stir 10 minutes, and in control procedure, temperature is below 40 ℃; Finally, with deionized water fine setting, the density of controlling the front lead plaster of discharging is 4.0-4.3g/ cm 3.
The invention has the beneficial effects as follows: a kind of Vehicular battery negative plate of the present invention lead paste formula and preparation method thereof, exists that specific energy is high, large current density power is strong, low temperature capacity is high and the lasting advantage that circulates.
Embodiment
First prepare lead paste formula, the shared percentage by weight of composition of formula is: lead powder 100kg, short fiber 0.03-0.10kg, active carbon 1300-1700g, titanium dioxide 10g, bismuth oxide 20g, sodium carboxymethylcellulose 100-150g, polytetrafluoroethylene 200-300 g, electrically conductive graphite 200-250g, aerosil powder 100-150g, deionized water 10000-11000g, concentration are 1.30-1.40g/ cm 3the sulfuric acid 8000-9000ml of (25 ℃).
First sodium carboxymethylcellulose (CMC), ptfe emulsion (PTFE) and deionized water are made to finely dispersed emulsion by the quality of 1:2:5 than mix and blend, as dispersion, binding agent, use; Again lead powder, short fiber, active carbon, titanium dioxide, bismuth oxide, electrically conductive graphite, aerosil powder are mixed, at the uniform velocity stir 10-15 minute, and in 1-3 minute, add the even emulsion with sodium carboxymethylcellulose (CMC), ptfe emulsion (PTFE) and deionized water preparation, ceaselessly at the uniform velocity stir 10 minutes; By ready concentration, be 1.3-1.4g/cm 3the sulfuric acid of (25 ℃) proportional quantity slowly adds, and continues to stir 10 minutes, and in control procedure, temperature is below 40 ℃; Finally, with deionized water fine setting, the density of controlling the front lead plaster of discharging is 4.0-4.3g/ cm 3.
