Magnets including a coating and related methods are described herein. The coating may include an aluminum manganese alloy layer. The aluminum manganese alloy layer may be formed in an electroplating process.


Metal surface pretreatments using ionic liquids prior to electroplating are disclosed. The surface treatments include forming an activated metal substrate surface by removing any naturally formed metal oxide layers formed on the surfaces of the metal substrates. According to some embodiments, the surface treatments include exposing the metal substrate to a non-aqueous ionic liquid. In some embodiments, an electrical current is applied to the metal substrate to assist removal of the metal oxide layer. The electrical current can be a pulsed anodic current. After activating the surface, a metal layer can be deposited on the activated surface. In some embodiments, the metal layer is electrodeposited in the same ionic liquid used to form the activated surface. The resultant metal coating is resistant to scratching and peeling.

Embodiments of electrodeposited current collectors and their methods of use and manufacturer described. For example, in one embodiment, an electrochemical power cell includes an anode including a first current collector and an anode active material deposited on the first current collector. The electrochemical power cell also includes a cathode including a second current collector and a cathode active material deposited on the second current collector. At least one of the first current collector and the second current collector is an electrodeposited aluminum foil. In another embodiment, a current collector includes a free standing foil made from electrodeposited aluminum.

During Phase I, Xtalic demonstrated the production of a new family of lightweight, high strength, good ductility alloys on a bulk scale; these alloys exhibit potential beyond the classical engineering metals suite. The scientific and engineering groundwork that has been established for electrodeposited nanostructured Al alloys (nano-Al) will be employed in this proposed Phase II project. The four main objectives are: (i) address technical aspects of large-scale production, (ii) demonstrate a production rate of 100 kg/day, (iii) develop and refine the process to reliably fabricate nano-Al alloys with properties demonstrated in Phase I and (iv) continue metallurgical analysis and mechanical testing. To achieve these goals, Xtalic will (i) design and construct a continuous reel-to-reel plating line, (ii) improve and optimize processing conditions to increase the manufacturing rate, (iii) expand the operating window and develop strategies to maintain consistent operating conditions and (iv) investigate and elucidate the deformation behavior of nano-Al alloys under unaxial tension tests at different rates and annealing conditions, as well as conduct biaxial tests to assess the formability of nano-Al sheets. Successful completion of the proposed work will demonstrate the feasibility of fabricating this new class of alloys at economically viable rates and volumes, as well as identify suitable applications for more rapid commercialization efforts.
