Lithium Diffusion in Vanadium Dioxide Nanobeams

Present Lithium Ion Battery is limited by how fast lithium and other small ions goes in and out the electrodes. Vanadium Dioxide as a unique system can provide visually monitoring of the motion of lithium ions inside. Through studying the diffusion process of lithium ion in vanadium dioxide nanobeams, we could better understand the process that limited the speed. It is directly related to the CEI in terms of energy storage. It’s also very important for the basic understanding the first order phase transition in vanadium dioxide, which has been well investigated for a long time in the lab.

“Providing clean energy to the inhabitants of our planet is a major challenge to future generations. The University of Washington is to be congratulated for establishing an Institute where faculty and students can work together to tackle the difficult global challenge of energy sustainability.”
– Mildred Dresselhaus, Professor of Physics and Electrical Engineering, Emerita and Institute Professor, Massachusetts Institute of Technology
“Energy competition is opening up in a variety of ways, the push for carbon control will continue, and the rate of technology advancement is exponential. All the things I’ve seen at the CEI are just perfect for the way we see things going in energy. You guys are at the cutting edge. We’re counting on you.”
– Ronald Litzinger, President, Edison Energy
Since its founding the Clean Energy Institute has contributed more than $1.1 million toward the education of 66 STEM scholars and recruitment of 12 students through our fellowship programs.
