Advanced Batteries via Tobacco Virus
Three steps are needed to make a TMV-based battery:
- Altering, growing, disseminating, and arranging the TMV.
- Treating the TMV to develop nanorods on a metal plate.
- Integrating the nanorod-surfaced plates into completed finished batteries.
A team of interdisciplinary scientists and their students at the University of Maryland helped make each step feasible. A solvent of genetically altered TMV was used to attach the rod-like virus particles to the metal conductor plate, and then the entire area was covered with a thin layer of nickel and other metals. This conducting layer acts an electric current accumulator in the presence of the battery’s electrochemical reactions. This novel handling method leads to the usage of less scarce and less expensive materials in the batteries, making it reasonably feasible to continue to develop these techniques.
TMV becomes torpid and inert during the build-up course. In reality, the resulting batteries do not “carry" the virus, and there is no possibility of transmitting the TMV virus to plant or human life.
"The resulting batteries are a leap forward in many ways and will be ideal for use not only in small electronic devices, but in novel applications that have been limited so far by the size of the required battery," stated Professor Reza Ghodssi at the A. James Clark School of Engineering and College of Agriculture and Natural Resources.
Herbert Rabin Professor of Electrical and Computer Engineering at the Clark School stated that the technique that they had developed could be utilized to generate tools to store energy for incorporated Microsystems like wireless sensors networks. These arrangements have to be in fact minute in size like millimeter or sub-millimeter. This will help it to be spread in big numbers in distant environments for practical applications like mother country security, agriculture, environ supervising and more; to control these devices, similarly tiny batteries are compulsory and keeping in mind not to compromise in performance.
