Synthesis and characterization of LiTi 2(PO 4) 3/C nanocomposite as lithium intercalation electrode materials

Journal Article


Abstract


  • The LiTi 2(PO 4) 3 has been successfully synthesized by a PEG (polyethylene glycol, mean molecular weight of 2000) based sol-gel route at a relative low temperature. For further improve its electrochemical properties, a ball milling process with acetylene black has been used to form LiTi 2(PO 4) 3/C nanocomposite. The samples are characterized by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. Electrochemical performance of the samples is characterized by the charge-discharge test and cyclic voltammetry. The results show that the ball milling process enables LiTi 2(PO 4) 3 nanoparticles networked with conductive acetylene black, which offered higher electrochemical performance. The LiTi 2(PO 4) 3/C nanocomposite delivers a higher specific capacity, enhanced rate capability, and better cyclability. �� 2012 Elsevier Ltd. All rights reserved.
