Description
Technical field
The present invention relates to the storage battery chemical synthesis technology, specifically is that storage battery changes into used equipment.
Background technology
The manufacturing process flow of lead acid accumulator comprises that lead powder manufacturing, grid manufacturing, pole plate manufacturing, pole plate change into, wash key steps such as oven dry and assemble.Wherein, pole plate changes into a link that is very crucial, will finish in this course by chemistry and the electrochemical conversion of the component of solidifying pole plate to both positive and negative polarity work active material, and promptly lead plaster generation electrochemical oxidation reactions generates PbO on the positive plate
2, on the negative plate spongy lead that electrochemical reducting reaction generates porous takes place simultaneously.Pole plate changes into to be divided into and outer change into and be internalized into, and changing into outward is pole plate to be contained in to add the dilute sulfuric acid charging in the electrolytic bath and it is changed into have active positive pole and negative plate, be assembled into storage battery then before assembling; Being internalized into is after green plate is assembled into battery, adds the dilute sulfuric acid charging and make it change into positive pole and the negative plate with activity in cell jar.The total cost that changes into outward is higher than and is internalized into, because it has increased the expense and the pole plate disposal cost of cleaning pole plate, cleaning the pole plate water simultaneously needs the expense that neutralizes and take out heavy metal element in recycling process or in the discharge process, and can cause serious environmental to pollute.Along with expanding economy, people's environmental consciousness strengthens gradually, requires storage battery production discharging more and more higher, or even " zero discharge ", reach this target and must take internal formation process to realize.
With the present battery of electric vehicle that has formed scale is example, if adopt outer changing into, its whole process times that change into (comprising cleaning, oven dry and additional) are between 96～120h, and the whole process times that are internalized into are about 120h, in the entire cell production process, changing into is the operation that the production cycle is the longest, the equipment input is maximum, the factory building area occupied is maximum, how to shorten the time of changing into, just become the minimizing investment in fixed assets, the key of enhancing productivity.Because the common pole plate that is internalized into is contained in the battery case and changes into, its sour volume is little, the density height, and the electric current that changes into is little, therefore β PbO in the positive active material that is generated
2Content is higher, and adhesion is less, intensity is lower.Though can reach very high initial capacity, be totally unfavorable for recycling deeply, the softening fault of active material appears easily, and must take corrective measure just can reach good result in the green plate manufacture process and in the internal formation process.If adopt low-density acid to be internalized into, because the electromobile battery volume is little, the acid amount is few, active matter quality is many, and after the sulfuric acid reaction in active matter and the electrolyte generated lead sulfate, the acid content in the electrolyte was extremely low, lead sulfate solubility sharply raises, and is easy to the phenomenon that is short-circuited during formation charging; As increase forming current, and because formation efficiency reduces greatly, the phenomenon of temperature superelevation then appears changing into, cause that electrolyte electrolysis amount evaporation capacity strengthens, and active matter seriously expands, even comes off, during the simultaneous temperature superelevation even send out and go up casing deformation.
At present, the domestic chemical synthesis technology that generally adopts is still outer to change into, but external, particularly advanced country generally adopts internal formation process, and it has mainly taked high temperature and cream, hot setting and big current cycle to discharge and recharge or the mode of large current pulse charging.High temperature and cream and hot setting are easy to realize, but, the big mode that current cycle discharges and recharges or heavy current pulse discharges and recharges is had relatively high expectations to charging/discharging apparatus: big current cycle discharges and recharges and needs equipment to have multistage to discharge and recharge program setting and operation (generally needing 30～100 sections) control and complicated operation, the heavy current pulse charging/discharging apparatus then needs special heavy current pulse charge-discharge machine, old equipment need be eliminated, therefore, need the bigger input of installations and facilities just can be achieved.This has become the big obstacle that internal formation process can not be promoted fast on electromobile battery.
Summary of the invention
