Preparation of cuprous chloride electrodes
Abstract
Abstract Electrodes for electrochemical cells are prepared from porous copper-containing carrier bodies by immersion at ambient temperature of such bodies in cupric chloride dissolved in an organic non-aqueous solvent such as methanol and subsequently washed in an organic compound capable of dissolving cupric chloride, e.g. methanol to remove excess cupric chloride and then dried in vacuo. The porous carrier bodies may be prepared by sintering arborescent copper powder selected from the group consisting of acicular form or dendritic form having an apparent density of between 1 and 2 first molded to desired shape then heated to about 700* C. in a reducing atmosphere for about one half hour. A conductive copper or copper plated support of metal gauge or perforated metal sheet may be incorporated in the powder during molding. In the alternative the copper carrier body can be molded from such copper powders agglomerated with an organic binder selected from the group consisting of polystyrene, polyethylene and polytetrafluoroethylene and this molded body immersed in cupric chloride dissolved in organic solvent such as methanol, with subsequent washing in organic compound such as methanol to remove excess cupric chloride and ultimate drying in vacuo. Electrodes and electrochemical cells utilizing said electrodes are also described.
