  • Method of making tin-based alloys for negative electrode compositions
    Patent number: 8586240
    Abstract: Powder milling techniques, tin-based alloys formed thereby, and the use of such alloys as electrode compositions for lithium ion batteries are provided. The alloys include tin and at least one transition metal but contain no silicon. The powder milling is done using low energy roller milling (pebble milling).
    Type: Grant
    Filed: July 27, 2012
    Date of Patent: November 19, 2013
    Assignee: 3M Innovative Properties Company
    Inventors: Jeffrey R. Dahn, Pierre P. Ferguson, Mark N. Obrovac, Dinh B. Le, James R. Landucci
