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).
