Abstract Title   Nanostructured Composites for High Capacity Anodes Abstract Author(s)   Justin Golightly, Vince Teofilo, Ashley Pietz, Jorge Bonilla, Lowell McCoy, Jane Bonvallet, and Mark Isaacson (Lockheed Martin Space Systems Company) Abstract Presenter   Justin Golightly Abstract   As part of an initiative to produce ultra high energy secondary batteries with an improved cycle life, preliminary results will be presented on efforts to develop an advanced anode material with high specific capacity and good cycle life. The extremely high theoretical specific capacity of silicon makes it an attractive anode material, but cycle life of silicon anodes is traditionally poor. Improved performance of silicon-based anodes is being targeted through a combination of nanostructuring and binder selection. Silicon nanoparticles are incorporated with a binder to form a porous electrode structure that withstands volume changes during the lithiation/delithiation process. Materials development will focus on improving cycle life with safe performance in mind. The high capacity anode materials are being developed to enable cell level energy goals of 260 Wh/kg.
