Recently, CNT and Graphene have been applied to rechargeable batteries and fuel cells. High electronic conductivity and high surface area are very attractive for rechargeable batteries and fuel cells in which reaction sites are two dimensional. In this presentation, some of examples of new lithium ion batteries, next generation batteries and fuel cells are introduced.
In some cases, electrode materials for battery and fuel cell do not have adequate electronic conductivity. For example, sulfur cathode and oxygen cathode have no electronic conductivity. In other cases, electrode material has very low electronic conductivity. In order to construct new battery and fuel cell by using these low electronic conductive materials, carbon additives have to be used to overcome such low electronic conductivity.
In this presentation, some examples of nano-carbon applications are introduced and the function of nano-carbon is discussed.
Flexible nanocarbon-based electrodes for enzyme biodevices
Department of Finemechanics, Tohoku University
Prof. Matsuhiko Nishizawa
Prof. Nishizawa received his doctor’s degree in engineering from Tohoku University 1994. He joined the Department of Applied Chemistry of Osaka University as an Assistant Professor (1995-1997). In 1997, he moved to Tohoku University and was promoted to a Professor in 2003. He also served as a team leader of JST-CREST (2008-2013). His main concern is BioMEMS technology, including the biological batteries, soft iontronic devices, and their applications in medical, cosmetic and healthcare fields.
The enzyme-modified electrodes are core components of bioelectrochemical devices such as biosensors and biofuel cells. The nanostructured carbon aggregates provides conductive network and huge surface for enzyme modification, and has played an active role in recent progress in the highly active enzyme electrodes. Here, totally organic skin paches (transdermal DDS patch and bioelectric plaster) composed of flexible enzyme electrodes will be presented.
