摘要
Nd3＋-doped Li1.05V3O8 was synthesized by liquid-state reactions combined calcination.The influences of Nd3＋ doping on physical and electrochemical performances of Li1.05V3O8 were investigated using X-ray diffraction （XRD）,cyclic voltammograms,a.c.impedance and galvanostatic charge-discharge tests,etc.Results indicated that Nd3＋-doped products had well developed crystal structure of layered LiV3O8 and uniform particle size distribution.Nd3＋ doping with a proper amount improved the initial discharge capacity,discharge voltage and ion conductivity of the cathode material to some extent.Nd3＋ did not participate in the electrochemical reactions and was beneficial to stability of the crystal structure during cycling.
