Metal Oxide-Carbon Nanocomposites for Aqueous and Nonaqueous Supercapacitors

Completed Technology Project

Project Description

Metal Oxide-Carbon Nanocomposites for Aqueous and Nonaqueous Supercapacitors
This Small Business Innovation Research Phase I effort focuses on development of novel metal-oxide-carbon nanocomposites for application in pseudocapacitive electrochemical supercapacitors. Specifically, nanocomposites based on manganese, titanium, tantalum and vanadium oxides will be incorporated, at the nanoscale level, with electrically conductive carbon supports. Our focus will be to combine the desired pseudocapacitive characteristics of metal oxides with high surface area and large electrical conductivity of carbon supports while achieving economical and scalable manufacturing. The proposed nanocomposite materials will be tested as electrode materials in aqueous and nonaqueous supercapacitors. The proposed project will be a joint effort on NanoScale Corporation and Battelle Memorial Institute. NanoScale's role in the effort will be to synthesize nanocomposite materials, characterize their physical and chemical properties, and to optimize them based on results of electrochemical testing carried out by Battelle. Battelle's role in the effort will be to take the metal oxides prepared by NanoScale and fabricate them into supercapacitor elements to be tested in half-cell and full-cell devices. NanoScale is uniquely qualified to carry out the proposed research due to its rich experience in development and scaled-up synthesis of nanosized materials, including materials for battery applications. NanoScale has worked previously on several projects related to battery technologies. More »
