摘要

Cathode materials prepared by a co-precipitation are 0.3Li_2MnO_3·0.7LiMn_(1-x)Ni_yCo_(0.1)O_2 (0.2≤x≤0.4) cathode materials with a layered-spinel structure. In the voltage range of 2.0-4.6V, the cathodes show more than one redox reaction peak during its cyclic voltammogram. The Li/0.3Li_2MnO_3·0.7LiMn_(1-x)Ni_yCo_(0.1)O_2 (x = 0.3, y = 0.2) cell shows the initial discharge capacity of about 200mAhg~(-1). However, when x=0.2 and y = 0.1, the cell exhibits a rapid decrease in discharge capacity and poor cycle life.
