Abstract

In this study, LiFePO₄ materials were prepared by using solid-state method. The prepared LiFePO₄ was further mixed with aqueous AgNO₃ and glucose solution to obtain the LiFePO₄/Ag nanocomposite materials through the reduction reaction. The results show that the prepared LiFePO₄/Ag materials have an orthorhombic olivine-type structure and a small amount of impurity Li₃PO₄ or Li₃Fe₂(PO₄)₂ was present in the product. Raman and TEM analysis shows that the addition of silver can induce more conductive grapheme and reduce the primary particle size of LiFePO₄.
