Department of Physics Li-ion batteries are the best portable energy supplies known to us today. Even so, they can be improved using new electrode materials. In this talk we will show how combinatorial materials science methods can be used for rapid synthesis and screening of thousands of new electrode materials. An atomic force microscope (AFM) housed inside an argon filled glovebox is used to study the change in morphology of interesting materials. Time lapsed AFM movies of the reaction of Li with an amorphous Si-Sn alloy which expands and contracts by over 100% will be shown.
