Abstract This work aimed at studying the possibility of preparing Wood alloy structures by cathodic codeposition of Bi, Pb, Sn and Cd from aqueous solutions. The metal ions were dissolved in a fluoborate medium. The reduction mechanisms of the single ions, studied using a rotating disc copper electrode or by linear sweep voltammetry, were simple with a single fast electron transfer step, except for the case of Bi, where the reaction was found to be irreversible. By potentiostatic codeposition of the four metals at a copper rotating disc electrode, metallic powders, having a composition close to that of the Wood alloy, with Bi, Sn, Cd and Pb7Bi3 phases, were prepared. These powders had homogeneous grains with micrometric sizes, and a specific surface of 1.5 m2 g−1. Their performances as lithium host structures in negative electrodes will be assessed.
