Electrical conductivity and thermoelectric power measurements (77-300 K) of both the pure and electrochemically doped with lithium Bi2Sr2CaCu2O8+delta system, are presented. Clear correlation between electronic and electrochemical properties of bismuth superconductor for the cell of Li/Li+/LixBi(2)Sr(2)CaCu(2)O(8+delta) type was shown.
