제목 NANOSTRUCTURED ELECTRODES FOR LITHIUM ION BATTERIES
초록 Without doubt, environmentally sustainable ways of making energy device is as important as the performance itself. To meet this dual requirement, a M13 virus based biological toolkit was utilized for controlling nanostructures of lithium ion battery electrodes. High power lithium ion battery cathodes were fabricated using genetically programmed multifunctional virus as a versatile scaffold for the synthesis and assembly of materials. A novel strategy for specifically attaching electrochemically active materials to conducting carbon nanotubes through biological molecular recognition was developed by manipulating the two-genes of the M13 virus. By developing this two-gene system, we facilitated a self-assembly method to realize true nanoscale electrical wiring for high power lithium ion batteries. This environmentally benign low temperature biological scaffold could activate new types of electrode materials that have been excluded because of their extremely low electronic conductivity.
