POSITIVE PLATE SULFATION CHARACTERISTICS OF THE LEAD-CALCIUM GRID BATTERY.
Abstract
Sulfation patterns in charged positives of thick and thin-plate lead-calcium grid cells, with and without H3PO4 additive, were determined autoradiographically. A mechanism is proposed to explain capacity maintenance behavior of these cells. Thickness and density of positive active material was more important for capacity maintenance than grid thickness or surface area. Improved thin-plate lead-calcium grid cells were developed utilizing: (1) H3PO4 incorporated in the positive paste mix for extended service life, and (2) a double-layer positive paste structure for improved capacity maintenance without sacrifice of the high discharge rate capability.
