Abstract

Through the PO₄³⁻ 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.
