• 一般注記: The effect of partial substitution of magnesium ou the electrochemical property of LiMn_2O_4 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 LiMn_2O_4 became indistinct with the magnesi doping. The reaction of LiMn_<l.8>Mg_<0.2>O_4 during lithium insertion and desertion was a homogeneous phase reaction. Electrochemical measurements revealed that LiMn_<1-x>Mg_xO_4 is a cathode active material appropriate for use at high rates. The optimum x value in LiMn_<1-x>Mg_xO_4 was found to be in the range of about 0.1 to 0.2.
