Stoichiometric Mg2+ and Ti4+ with different proportions were doped to prepare the LiFe1-x-yMgxTiyPO4 cathode materials by high temperature solid state method. The samples were investigated with XRD, SEM and charge/discharge measurements. Results show that doping of Mg2+ and Ti4+ distinctly changes the paticle sizes and morphologies, which leads to a improvement of electrochemical performance. The mix-doped LiFe0.98Mg0.01Ti0.01PO4 material shows the best electrochemical performance due to its smaller crystalline particles and lower the polarization. At the discharge rate of 0.1C, the initial specific capacity of LiFe0.98Mg0.01Ti0.01PO4 is 105.78 mAh·g-1, its high-rate performance is also better.

Graphite Structure

Carbon-coated Li4Ti5O12 (LTO) has been prepared using polyimide (PI) as a carbon source via the thermal imidization of polyamic acid (PAA) followed by a carbonization process. In this study, the PI with different structures based on pyromellitic dianhydride (PMDA), 4,4′-oxydianiline (ODA), and p-phenylenediamine (p-PDA) moieties have been synthesized. The effect of the PI structure on the electrochemical performance of the carbon-coated LTO has been investigated. The results indicate that the molecular arrangement of PI can be improved when the rigid p-PDA units are introduced into the PI backbone. The carbons derived from the p-PDA-based PI show a more regular graphite structure with fewer defects and higher conductivity. As a result, the carbon-coated LTO exhibits a better rate performance with a discharge capacity of 137.5 mAh/g at 20 C, which is almost 1.5 times larger than that of bare LTO (94.4 mAh/g).
