Description
Technical Field
The invention relates to the technical field of lead storage batteries, in particular to a super-energy alkene polymer lead storage battery green plate lead plaster.
Background
At present, the vehicle battery generally has the defects of difficult low-temperature starting in winter, low safety coefficient, short service life, easy water loss at high temperature, easy thermal runaway, high battery recycling and regenerating cost, poor charging capability and the like. The automobile is frequently started and stopped in the starting and stopping process, so that the service life of the battery is shortened. The vehicle rapid start-stop technology requires that a battery has enough electric quantity and good discharge characteristic even if the battery is frequently used in a partial charge state; meanwhile, the charge current has to have excellent charge characteristics, and can accept high-rate charge current, namely, the charge current has good dynamic charge acceptance.
The principle of the AGM battery is to contain a large capacity in a small space so that the AGM battery can fully meet the requirement of a start-stop system on a storage battery. The traditional AGM battery has the characteristics of long service life and strong starting capability, but when the AGM battery is applied to starting and stopping automobiles, a negative plate is very easy to be sulfated when being in a partial charge state for a long time, the charging acceptance performance, particularly the dynamic charging acceptance performance, is poor, and the service life of the battery is terminated due to the difficulty in charging, so that the starting and stopping requirements are difficult to meet. If the carbon material with higher content is added, although the performance of the lead-acid storage battery is improved, such as the electrical conductivity is increased, the lead sulfate is uniformly distributed, the specific surface area is increased, the polarization is reduced, the capacitance effect is increased, and the like, the lead-acid storage battery also has some adverse effects, such as the fact that a large amount of carbon is directly added into the negative lead paste, the lead paste is easy to fall off in the circulating process, and the service life of the battery is shortened; and the defect of low high-temperature resistance is also caused, and the normal use of the lead-acid storage battery in matched products is seriously influenced.
In order to overcome the defects, in recent years, many colloid-type start-stop batteries have appeared, and the colloid electrolyte is slightly better than the batteries made of sulfuric acid solution in comprehensive performance, but the defects of quick capacity attenuation, low specific energy, thermal runaway, overlarge charging acid mist, difficulty in low-temperature starting and the like generally exist, the problem of start-stop requirements is difficult to solve, the requirements of markets and industries are difficult to meet, and the requirements of energy conservation and emission reduction and the requirement of the national ministry of environmental protection for promoting clean production cannot be met.
