“…Researchers have used a variety of methods to measure these distributions. Asai et al [1] calculated the potential and current distributions of tall tubular positive plate under discharge on the basis of the plate resistance and the current-potential-time relationship. Sunu et al [2] obtained the current density distribution by measuring grid voltage drop and electrode polarization.…”

The distributions of current density and potential of automotive negative plate were studied by measuring the IR drop in the H 2 SO 4 solution between the positive and negative plates. At the beginning of discharge, the distributions of current density, potential and polarization resistance are uniform. In the later stage, high polarization appears at the top and bottom of the negative plate and the current density falls very quickly in these regions. Therefore, high polarization resistance of the active mass increases very quickly at both the top and bottom of the negative plate. It is mainly caused by the passivation of the negative plate which obviously decreases by constant current charge. At low temperature, at the end of 3 C discharge, the highest polarization and the lowest current density appear farthest away from the lug and at the top of the negative plate.

“…Studies of the distributions of current density and potential in lead-acid batteries have mainly focused on the grid and the positive plates [1][2][3][4][5][6][7][8][9][10][11][12]. Little attention has been paid to the negative plates.…”
