Abstract

The application is directed to products and methods related to an aluminum electrolysis cell with a non-carbonaceous substrate with a directing feature. The directing feature can be configured to direct a wettable material in a predetermined direction. The non-carbonaceous substrate can be at least partially covered with solid aluminum metal. The wettable material can be aluminum metal.
