ABSTRACT:
A system and a method useful in the formation of electrodes for use in electrochemical cells are disclosed. The system includes a pair of conductive end electrodes spaced apart from one another and situated in an aqueous electrolyte. A pair of precursor electrodes are placed in the electrolyte, between the end electrodes. Each of these precursor electrodes comprise a material to be selectively reduced or oxidized disposed on a conductive substrate. The precursor electrodes are in a configuration substantially precluding contact between the electrolyte and the substrates thereof. The end electrodes and the precursor electrodes are in electrical contact with a power supply to effect a current flow in the electrolyte thereby reducing or oxidizing the material of the precursor electrodes. Restraining forces are applied to the precursor electrodes to substantially maintain the dimensions thereof during the electrode charging process. The system includes a separator effective in permitting the electrolyte to contact the precursor sand terminal electrodes, while permitting substantially uniform application of restraining forces to the precursor electrodes. The system can also include a semi-permeable membrane situated between the end electrodes and the precursor electrodes. The semi-permeable membrane is effective in preventing migration of the material to be reduced or ozidized from the precursor electrodes to the end electrodes, while permitting ionic charge transport therebetween.
