“…The experimental data comes from previous work done by Edwards and Srikanth [1]. 5, the numerically determined capacity of the modeled plates compares favorably with the experimental data reported in Edwards and Srikanth [1]. To simplify the figure, only one experimental curve is given for each computer generated curve.…”

“…To simplify the figure, only one experimental curve is given for each computer generated curve. In reference [1], plates with the 34% loading of glass microspheres appeared to be close to an optimal loading. However, the shape of the experimental curves differs from the curves predicted by the model.…”

In this paper, we summarize previous work [1][2][3][4][5][6] that helped to establish the physical processes limiting the capacity of lead-acid batteries. .Ion diffusion and paste conductivity are the dominate processes that limit capacity over a wide range of discharge rates. A model which includes both these processes was developed and used to understand the role of additives in the positive paste. With a basic understanding of the physical mechanisms limiting capacity and equipped with the model, we are pursuing designs for dramatically improving the capacity of lead-acid batteries. Some of these designs will be discussed in this paper.
