This performance indications to relevant equipment has strict demand, particularly security, reliability index requirements very high.For example, the sector
The service lifetime of accumulator of the supporting wind-powered electricity generation of design specification requirement or solar power plant is 15 years, in terms of daily discharge and recharge once
Calculate, with 5500 charging and discharging capabilities.Current commercially available lead-acid accumulator average life only has 1000 times or so, this index
It is remote not reach the supporting requirement of renewable sources of energy energy storing devices.In the market some advanced technology, the lithium battery of function admirable, fuel cell
Although and ultracapacitor service life many stronger than lead-acid accumulator, its application cost is big, so being also not suitable for Regenerated energy
Source matching equipment.The obvious weakness that traditional lead-acid accumulator is present is that service life is not long, in addition, other major techniques
Performance is very prominent, and particularly capacity is big, safe, and manufacturing cost and use cost is low.Reality explanation, as long as overcoming plumbic acid to store
The weakness of battery, the supporting requirement with regard to renewable sources of energy energy storing devices can be met.Understand lead-acid accumulator in energy storage through analysis, research
Under scene invalid position be negative plate by sulfation, if adding appropriate carbon material in cathode lead plaster, just can effectively improve
Negative plate sulfuric-resisting salinization ability, is in other words exactly the service life for improving lead-acid accumulator.But, carbon material and negative pole lead powder
Physical property is different, and compatibility is poor, is difficult to accomplish uniform mixing using routine and cream technique, heterogeneous cathode lead plaster is still
Expected service life is not reached.
The content of the invention
Present invention is generally directed to prior art toward the problem of addition carbon material is difficult to homogeneous in cathode lead plaster, propose that one kind contains
There is the cathode lead plaster homogenization of carbon material, the technique realizes homogeneous purpose by premixing, the scattered and whole mixed processes of acid, on
State process easy, reasonable, be also easy to implement.
The present invention is achieved through the following technical solutions technical goal.
Cathode lead plaster homogenization containing carbon material, it, which is theed improvement is that, follows these steps to implement：
1.1 measure carbon material and low-density acid by weight percentage, and the carbon material accounting taken is the 20~25% of low-density acid；
1.2 are placed in the low-density acid measured in dispersing apparatus；
1.3 are then homogeneously added into carbon material in dispersing apparatus, and carbon material and low-density acid divide at a high speed through 20~30min
Premix is obtained after dissipating processing；
1.4 filter out the low-density acid being had more than needed in premix, obtain paste carbon material；
1.5 and cream, lead powder and additive first are measured by proportioning, then paste carbon materials are added by the 10~12% of taken lead powder weight
Material, addition manner is added in lead powder in the lump using paste carbon material with additive, and negative electrode lead is mixed to get through 30~40min homogeneous
Cream.
As further improvement project, the sour density of the low-density acid is 1.20~1.24g/cm3。
As further improvement project, the premix is filtered 58~62% low-density acid.
As further improvement project, dispersing apparatus running speed is 2000~3000r/min.
The present invention compared with prior art, has the positive effect that：
1st, carbon material and low-density acid are pre-mixed in dispersing apparatus, the process is easy, implement easy；
2nd, the uniformity that the carbon material through premixing is obtained to a certain extent is disperseed, and is that follow-up homogeneous and cream create conditions；
3rd, the low-density acid being had more than needed in premix is filtered out, has both been easy to follow-up homogeneous and cream, low-density acid has been reclaimed again, has been risen
Environmental pollution is also reduced to the effect for saving production cost.
