Abstract

One of the themes of the sodium-sulphur cell development is to achieve a high energy efficiency of more than 80 per cent. As the coulomb efficiency of this cell is almost 100 per cent, the energy efficiency is determined only by the cell internal resistance. In order to minimize the cell resistance, it is necessary to improve the cell structure based on accurate evaluation of the potential distribution and the cell resistance without any geometrical simplification. The authors propose an effective method to calculate the potential distribution and the cell resistance of a sodium-sulphur cell. The calculated results of the network model show a little discrepancy with the measured values, because the network method assumes one dimensional geometry, and neglects longitudinal potential profile.
