“…As a tritium breeding blanket material for fusion reactors, Li and Pb alloy with at%, namely, Li 17 Pb 83 has attracted considerable interest, 1 because of its advantages, [2][3][4] such as good tritium breeding, low Li vapor pressure, moderate melting temperature and high blanket energy multiplication. Therefore, Li-Pb alloy has been widely studied, for example, in studies on the solubility of hydrogen in Li-Pb eutectic alloy, [5][6][7][8][9][10][11] the density and surface tension of Li-Pb melts, 12 the compatibility of structural materials with the liquid Li-Pb alloy 13,14 the thermodynamic properties of Li-Pb alloys, [15][16][17][18][19] etc.…”

The electrode reaction of Pb(II) and co-reduction of Li(I) and Pb(II) were investigated on a tungsten electrode in LiCl-KCl eutectic melts by a range of electrochemical techniques. From cyclic voltammetry and square wave voltammetry measurements, the reduction of Pb(II) was found to be a one-step diffusion-controlled reversible process with the exchange of 2 electrons. The diffusion coefficients of Pb(II) were computed, and they obey the Arrhenius law. Using the linear polarization technique, the kinetic parameters, such as exchange current intensity (j 0 ), standard rate constant (k 0 ) and charge transfer resistance (R ct ) for the Pb(II)/Pb(0) couple on a tungsten electrode were studied at different temperatures, and the activation energy is 27.32 kJ mol À1 , smaller than the one for diffusion of Pb(II), which further confirmed that the reduction of Pb(II) was controlled by diffusion. A depolarisation effect for Li(I) reduction was observed from the results of cyclic voltammetry, square wave voltammetry and chronopotentiometry due to the formation of Li-Pb alloys by co-reduction of Li(I) and Pb(II). Furthermore, five Li-Pb intermetallic compounds, LiPb, Li 8 Pb 3 , Li 3 Pb, Li 10 Pb 3 and Li 17 Pb 4 characterized by scanning electronic microscopy and X-ray diffraction, were selectively prepared by potentiostatic electrolysis on a tungsten electrode and galvanostatic electrolysis on a liquid Pb electrode, respectively.
