Synthesis and properties of layered-LiMn0.5Ni0.5O2 material |
|
| Abstract: | Development and application of low-cost cathode material plays a crucial role in finding a broad range of uses for lithium ion batteries. Layer-structural LiMn0.5Ni0.5O2 was synthesized by solid-state reaction at high temperature. Its structure characterization was investgated by XRD and electro-chemical properties were tested by constant current method. Al doping of this material was also carried out. The results show that the synthesized material with Al doping has good electrochemical properties and can be used as cathode material for lithium ion batteries. |
