Abstract
The invention provides a method for passive metal activation and uses thereof. Disclosed is a method for activating a surface of metals, such as self- passivated metals, and of metal-oxide dissolution, effected using a fluoroanion- containing composition. Also disclosed is an electrochemical cell utilizing an aluminum-containing anode material and a fluoroanion-containing electrolyte, characterized by high efficiency, low corrosion, and optionally mechanical or electrochemical rechargeability. Also disclosed is a process for fusing (welding, soldering etc.) a self-passivated metal at relatively low temperature and ambient atmosphere, and a method for electrodepositing a metal on a self-passivated metal using metal-oxide source.
