Patent number: 9082524Abstract: A metal oxide-carbon composite includes a carbon aerogel with an oxide overcoat. The metal oxide-carbon composite is made by providing a carbon aerogel, immersing the carbon aerogel in a metal oxide sol under a vacuum, raising the carbon aerogel with the metal oxide sol to atmospheric pressure, curing the carbon aerogel with the metal oxide sol at room temperature, and drying the carbon aerogel with the metal oxide sol to produce the metal oxide-carbon composite. The step of providing a carbon aerogel can provide an activated carbon aerogel or provide a carbon aerogel with carbon nanotubes that make the carbon aerogel mechanically robust.Type: GrantFiled: January 15, 2014Date of Patent: July 14, 2015Assignee: Lawrence Livermore National Security, LLCInventors: Marcus A. Worsley, Thomas Yong-Jin Han, Joshua D. Kuntz, Octavio Cervantes, Alexander E. Gash, Theodore F. Baumann, Joe H. Satcher, Jr.
