摘要：

Measurements of discharge polarization in 40 Ah sodium-sulfur cells have been performed. The voltage relaxation rate as a function of state of charge was monitored over a period of several hours. Relaxations of the order of seconds were determined using an ac impedance technique. The data were combined to construct an impedance model of a sodium-sulfur cell which includes a Warburg term which varies as a function of state of charge. © 1990, The Electrochemical Society, Inc.
