The distribution of potential and electrochemical reaction rate in molten polysulphide elecrodes (TN-EC-001)

A simple mathematical derivation is given of the distribution of potential in a porous carbon electrode saturated with molten sulphur/sodium polysulphide. The equations show how the spatial distribution of reaction products in the sodium/sulphur cell depends on the relative electrical resistivities of the melt and the carbon matrix and, also,...
