This project will address the feasibility of an ambient temperature chloroaluminate ionic liquid as a medium for efficient electroplating of high-quality aluminum. The chloroaluminate, composed of a mixture of aluminum chloride and an organic chloride salt, is liquid at room temperature. These media promise highly effective plating of crystalline, nondendritic, nonporous aluminum. This process will offer several practical advantages for aluminum electroplating, including dramatic reduction of organic solvent consumption compared to current processes. The ionic liquid medium will significantly reduce or eliminate volatile organic compound emissions, contributing toward environmentally benign processing and reducing environmental impact of aluminum plating technology.
