Research On Optimization Of Formation Process Of The Automotive Lead-acid Batteries Plates

Lead-acid batteries have the advantages of low cost,stable performance and mature technology,which are widely used in automobiles,electric vehicles and other industrial power supplies.In a series of lead-acid batteries in the production process,the chemical process is one of the most important aspects.Achievement is the initial charge of the battery plate for the first time,the effect of the plate into a direct impact on the basic performance and battery life.Affect the battery into a lot of factors,such as chemical methods,plate thickness,electrolyte density,charging current program and the formation of temperature.Traditional technology into a larger energy consumption,longer time and other issues.In order to improve the chemical conversion efficiency,aiming at the automotive starting-up maintenance-free lead-acid batteries,the internalization process was adopted,and the reaction mechanism of the battery formation was taken into account.According to the national standard of the battery performance testing and plate composition testing,analysis of electrolyte density,charging current program and the formation of temperature on the degree of formation of the plate and the battery performance,in order to find the best route.The results show that the appropriate changes of the battery into the current,did not have a significant impact on battery performance,positive plate PbO₂ and negative plate PbO content or less.Two plus acid density control at 1.40g?cm^-3,the temperature control between 15⁵0?better.Some parameters of the existing chemical equipment and applications have been adjusted and optimized,which has laid the foundation for the production of high-performance and cost-effective battery products.
