摘要

The structure and properties of LiFe_0.9V_0.1PO₄ were investigated. LiFe_0.9V_0.1PO₄ has the same structure as LiFePO₄. Rietveld refinement indicates that vanadium atoms randomly substitute for iron atoms in the LiFePO₄ structure. The cathode properties of LiFe_0.9V_0.1PO₄, including reversible capacity, cycle number and charge–discharge current are better than those of LiFePO₄.
