Abstract
A composite electrode for supporting an anodic or cathodic electrochemical reaction such as occurs during a metal electrowinning process has a composition which includes between 90 and 95 weight percent of an electrically conductive metal compound and between 5 and 10 weight percent of a polymeric binder material blended with the conductive metal compound. The composite electrode is formed under a maximum pressure of 2.5 metric tons per square centimeter and at a temperature between ambient and 140 degrees C.
Claims8
A composite electrode for supporting an electrochemical reaction, comprising:
- (a) a mixture composed of between 90 and 95 weight percent of an electrically conductive metal compound powder and between 5 and 10 weight percent of a polyethylene blended with said metal compound powder;
- (b) said mixture being pressed to form said composite electrode in a monolithic structure having a substantially uniform composition at ambient temperature to bond the components of said mixture together.
