| Research Abstract |
We have been developing "organic radical batteries" by fabricating the prototypes using organic radical polymers as electode-active materials. The radical batteries are characterized by the unprecedented battery performances that accomplish both a high energy density and an excellent power rate capability, taking advantage of the designable polymer chain and the fast electron transpfer kinetics found for the radical pendants. The present research aims at establishing novel organic electrodes by unraveling the the electron-and mass-transfer processes of the radical polymers, in pursuit of basic principles that dominate the organic redox reactions through singly occupied molecular orbitals(SOMO). Rational molecular design and synthesis of radical polymers have been attempted with a view to further improve the energy and power densities to provide next-generation and sustainable organic rechargeable batteirs.
