Title: Impedance measurements on sealed lead--acid cells. [2. 5 Ah, 10 Hz to 500 kHz]

Abstract

The impedance of sealed 2.5-ampere-hour lead--acid cells was measured as a function of state of charge at frequencies of 10 Hz to 500 kHz. The impedance of a small lead--acid wet cell employing flat-plate electrodes was also measured over this frequency range. Comparisons between the results for these two cell types indicate that impedances are sensitive to chemical and physical changes which accompany cell discharge. A model is proposed which relates inductive behavior for porous electrodes to the electrode structure. Double-layer capacities are estimated for the two types of lead--acid cells. 8 figures, 1 table.
