| 摘 要： | A method of preparing the spinel LiV_(x)Mn_(2-x)O_(4) with liquid phaseis introduced at a low temperature. With cyclic voltammogram and discharge-charge tests at content current, we find that the doped vanadium leads to the spinel structure more stable, the reversible behaviors of LiV_(x)Mn_(2-x)O_(4)is improved, and the capacity fade on cycling is reduced.The cycle life of the battery based on LiV_(x)Mn_(2-x)O_(4)is also found improved.
