Degradation analysis of the lead acid battery plates in the manufacturing process

This paper presents a degradation analysis of the lead acid battery plate during the manufacturing process. The different steps of the manufacturing process of plate such as manufacturing of lead oxide, paste mixing and manufacturing of grid, pasting, curing and drying are described by Structured Analysis and Design Technique (SADT). The general analysis of all the causes and potential factors causing a low quality of the plate during the manufacturing process is created by the Ishikawa diagram. This description is completed by the Causal Tree Analysis in order to seek the various possible combinations of events leading to the low quality of lead acid battery plate during the pasting, curing and drying process.
