Accumulator high speed drives engine start.It is dirty that start stop system effectively solves tail gas caused by auto idle speed fuel oil burn incompletely
Dye and unnecessary oil consumption, but since battery frequently uses (interior electricity consumption device and startup engine), to the deeper cavity of battery
Service life and quick charge capability propose very high requirement.
Common startup battery (non-start stop system), 50%DOD deep-cycles are about 40-60 times, or even less, failure
Pattern softens for active material.Start and stop battery is to solve the softening of cyclic process active matter, and most efficient method is to improve active matter
Matter density.But improve density, it is meant that active material micropore becomes smaller, and carrys out great resistance to electrolyte permeable belt.It is highly dense
Degree chemical conversion is difficult and generates that particle large capacity is low but α-the PbO of long lifespan2Active material configuration；Low-density then causes production a large amount of
The tiny service life β-PbO of poor of particle2Active material configuration.By largely testing, the results showed that, work as positive electrode active material
Matter structure is α-PbO2:β-PbO2About 50%:When 50%, there is moderate capacity and preferably deeper cavity service life (50%DOD
Up to 400 times, for common start battery 8-10 times).
Traditional lead-acid battery formation method generally uses lower temperature, smaller current, to prevent active material in high temperature
And it is loosened under heavy current impact.Traditional chemical synthesizing method, the start and stop battery that can not be designed high density lead plaster are effectively melted into；
Or must take very long and make active material the reaction was complete, but highdensity active material configuration will be destroyed, to seriously affect
Battery deeper cavity discharge life.This patent method utilizes chemistry under high temperature using chemical conversion preliminary stage high temperature and high current method
Reaction accelerates and early period has the characteristic of soaking ability to accept, has both ensured that active material configuration was not destroyed while making activity
Substance reaction fills part as far as possible, to reach the optimum activity structure of matter ratio that deeper cavity start and stop are applied.
