Preparation and characterization of LiFePO<inf>4</inf>/Ag nanocomposites for application in Li-ion batteries

Abstract

In this study, LiFePO 4 materials were prepared by using solid-state method. The prepared LiFePO 4 was further mixed with aqueous AgNO 3 and glucose solution to obtain the LiFePO 4 /Ag nanocomposite materials through the reduction reaction. The results show that the prepared LiFePO 4 /Ag materials have an orthorhombic olivine-type structure and a small amount of impurity Li 3 PO 4 or Li 3 Fe 2 (PO 4 ) 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 LiFePO 4 .
