DNA-directed growth of FePO4 nanostructures on carbon nanotubes to achieve nearly 100% theoretical capacity for lithium-ion batteries

Abstract

Through the PO4 3 groups regularly arranged on its sugar-phosphate backbone, DNA is used to direct the growth of a network structure of ultrasmall FePO4 nanoparticles on double-wall carbon nanotubes. The resulting structure has achieved nearly 100% theoretical storage capacity for the FePO4 active component as a cathode in lithium-ion batteries.
