Özet:

 

Presently intercalation type graphite anode electrodes were being used mainly in the commercial Li-ion batteries. Graphite electrodes, however, have reached their theoretical capacity values ( 372 mAhg-1). Therefore large amount of studies on the synthesis of the novel electrode types were conducted all over the world. One of the novel electrode groups is conversion type electrode. The high entropy design approach is especially utilized in this multi-component oxide electrode synthesis.  In this study a new high entropy oxide (Mg0.2Co0.2Ni0.2Zn0.2Li0.2)O was synthesized for the first time in the literature by mixing and grinding of the oxide powders, followed by solid-state reaction at 1000 ºC. The microstructure of the material was characterized using XRD and FESEM-EDX methods, showing single-phase rocksalt structure. The electrochemical performances of the synthesized (Mg0.2Co0.2Ni0.2Zn0.2Li0.2)O as anode material for Li-ion batteries was determined using LIR2016 coin cell. The results showed that (Mg0.2Co0.2Ni0.2Zn0.2Li0.2)O, which has good potential to be used as anode in lithium-ion batteries, had the highest capacity value in 1.0 M LiTFSI-DME electrolyte (1725 mAhg-1).
