Abstract

The effect of partial substitution of magnesium on the electrochemical property of LiMn2O4 has been investigated. As a result of magnesium doping, the specific surface area decreased. In addition the lattice constant decreased along with the polarization at a high discharge rate and an excellent cycle performance was realized in exchange for somewhat of reduction of the capacity. The voltage jump of 4.1 V for the discharge curve of LiMn2O4 became indistinct with the magnesium doping. The reaction of LiMn1.8Mg0.2O4 during lithium insertion and desertion was a homogeneous phase reaction. Electrochemical measurements revealed that LiMn(1-x)MgxO(4) is a cathode active material appropriate for use at high rates. The optimum x value in LiMn1-x MgxO4 was found to be in the range of about 0.1 to 0.2.
