| 摘 要： | Based on synthesizing pure spinel type lithium manganese oxides, the derivations such as LiMn1.5Ti0.5O4, LiMn1.5Fe0.5O4, LiMn1.5Ni0.5O4 and LiMn1.5Zn0.5O4 were prepared using solid-step-sintering method. The structures were characterized by using XRD, SEM and laser granulometer. The electrochemical measurement results show that the element of iron or nickel can raise the discharging plateau voltage of LiMn2O4 , and element titanium improves the electrochemistry property of LiMn2O4 little, while element zinc destroys the electrochemistry property of LiMn2O4. The influence of elements of titanium, iron, nickel, or zinc on the structure of LiMn2O4 pure phase was discussed from the viewpoint of structural chemistry.

| Abstract: | Based on synthesizing pure spinel type lithium manganese oxides, the derivations such as LiMn1. 5 Ti0. 5-O4, LiMn1.5 Fe0. 5 O4, LiMn1.5 Ni0.5 O4 and LiMn1.5 Zn0. 5 O4 were prepared using solid-step-sintering method. The structures were characterized by using XRD, SEM and laser granulometer. The electrochemical measurement results show that the element of iron or nickel can raise the discharging plateau voltage of LiMn2 O4, and element titanium improves the electrochemistry property of LiMn2 O4 little, while element zinc destroys the electrochemistry property of LiMn2O4. The influence of elements of titanium, iron, nickel, or zinc on the structure of LiMn2O4 pure phase was discussed from the viewpoint of structural chemistry. |
