Electrochemical Behavior of LiCo_yMn_(2-y)O_4 (0<=y<=1) spinels synthesized from Co_(3y/2)Mn_(3-3y/2)O_4 precursor at different temperatures.

摘要

To improve cyclability at 4V doping of LiMn_2O_4 with iso-or aliovalent cations have been done (1).Among the dopant cations,the Co-doped spinels have shown the best electrochemical performance (2).We present the electrochemical properties in the 3.5-5.2V range in a lithium cell in which the positive active material is Co-doped spinels synthesized at several temperatures by using an original procedure designed by us (3).
