Análise do tempo de cura nas placas positivas de baterias automotivas.

Abstract

In the production of lead-acid batteries, the main step is the curing process of pasted plates. Although there are a good number of studies dealing with the healing process, mainly with the objective of optimizing the stage and improving the performance of the batteries, there is a need for a systematic study of this process. Thus, the main objective of this work is to evaluate the influence of different curing times for the positive plate in the automotive battery manufacturing process. As well as, analyze the results obtained in mass / mass adhesion tests, scanning electron microscopy (SEM) and X-ray diffractogram (XRD). From the results obtained, it was possible to verify that the extension of the curing time improves the quality of the plate and, consequently, increases the useful life of the accumulator.
