A system (10) and a method useful in the formation of electrodes for use in electrochemical cells are disclosed. The system includes a pair of conductive metallic terminal electrodes (12, 14) spaced apart from one another and disposed in an aqueous electrolyte (16). The terminal electrodes are in electrical contact with a power supply (30) to effect a flow of current in the electrolyte away from the first of the terminals and toward the second of the terminals. At least one precursor electrode (17) comprising a material to be reduced or oxidized in electrical contact with a conductive backplate is disposed in the electrolyte between the terminals. The precursor electrode is orientated relative to the terminal electrodes so as to effect the reduction or oxidation of the material thereof. Restraining forces are applied to the precursor electrode to substantially maintain the dimensions of the precursor electrode during its reduction/oxidation. The system includes a separator (26) effective in permitting the precursor and terminal electrodes to interface with the electrolyte. The separator permits a substantially uniform application of the restraining forces to the precursor electrode. No electrical contacts are made directly to the electrodes being formed, this process then being a contactless charge. |
