Abstract

A series of supervalent cation doped Li_1-x M _0.01Fe_0.99PO₄/C composites (M∈=∈Ti, Zr, V, Nb, and W) were synthesized by solid-state reaction. The effects of the heteroatoms were studied by X-ray diffraction, cyclic voltammetry, and electrochemical impedance measurement. After doping, the lattice structure of LiFePO₄ is not destroyed and the reversibility of lithium ion intercalation and deintercalation is improved. The diffusion coefficient of lithium ions depends on the radius of the heteroatoms. As the radius of the heteroatom is larger, the diffusion coefficient increases.
