Researchers at Pacific Northwest National Laboratory and Princeton University are using self-assembling films of SnO2-graphene nanocomposites to form stable, alternating layers of nanocrystalline metal oxide and graphene. These composites achieve near-theoretical specific energy densities for Li-ion energy storage without exhibiting significant degradation during repeated charge/discharge cycles.
The article describing this study has been published in ACS Nano (2010) and appears in a special video issue listing the 2010 most-accessed articles in ACS Nano and Nano Letters. A production of the American Chemical Society, the accompanying video features interviews with PNNL researcher Jun Liu and Prof. Ilhan Aksay of the department of Chemical and Biological Engineering at Princeton.
