The thickness of applied lead paste is critical in the performance and manufacture of lead–acid batteries. Too little lead paste decreases the battery capacity, whereas too much lead paste is wasted cost in the manufacture of batteries. Paste thickness is increasingly becoming a key factor for absorbent glass mat (AGM) batteries. In the production of AGM batteries the plates are pressed into a cell under compression and therefore, compared with flooded batteries, plate thickness plays a more critical role in battery performance and cell balancing. This presentation discusses the methods, challenges and implications of more stringent inspection and control of lead paste thickness. Topics covered include contrasting plate weight control vs. plate thickness control; a description of the technology, and an example case study.
