Análise de sistema eletroquímico chumbo-ácido via modelagem entrópica.

Abstract

The application of enhanced methodologies for analysis and optimization is considered a decisive factor for the growth and consolidation of an industrial process. This work describes an analysis of the electrochemical lead-acid reactive system based on entropic modeling, aiming to establish a basis for a subsequent optimization of such systems. The methodology was developed from mass, ionic, enthalpic and entropic balances normally applied to continuous reactors. Applying such methodology in the reactions of discharge of the lead-acid battery it is possible to observe how the entropy of the system behaves and in this way, to direct the strategies of optimization for the system. The modelling shows to be appropriate to describe this case, presenting essentials details and being also able to describe complexes reactive redox systems for example of the electrochemical reactions that govern the performance of lead-acid batteries.
