| Abstract: | Nb doped LiNi0.5Mn15O4 cathode materials have been successfully synthesized through solid state reaction. XRD and charge/discharge tests have been employed to characterize the crystal structure and electrochemical performances of the obtained materials. The results show that Nb doping could induce the presence of LiNbO3 impurity, which can damage the discharge capability of obtained cathodes, while LiNio.425Nb0.03Mn1.504 with trace Nb doping demonstrates promising discharge capability under high current densities. |
