| 제목 | Effect of structural and electrochemical properties of Yttrium-doped Li[Ni0.8Co0.1 Mn0.1]O2 electrode by co-precipitation for lithium ion-batteries |
| 초록 | Ni-rich system Li[Ni0.8Co0.1Mn0.1]O2 of lithium secondary battery cathode material keep a high discharge capacity. However, by the Ni content increases, there is a problem that the electrochemical properties and stability of the structure are reduced [1]. In this study, a positive-electrode material in a lithium secondary battery Li[Ni0.8Co0.1Mn0.1]O2 was synthesized a precursor by co-precipitation. Cathode material was synthesized by adding yttrium. The yttrium doped materials have studied the structural and electrochemical properties. The yttrium doping expanded the pathway for Li+ to intercalate and deintercalate [2]. Also, it was improved that the structural stability and restraining the increase of charge transfer resistance of cathode during cycling [3]. As a result, synthesized cathode material Increased stability of the layered structure was observed by SEM(scanning electron microscope) and XRD(x-ray diffraction) and charge transfer resistance is lowered by EIS(electrochemical impedance spectroscopy) Keyword: cathode material, yttrium doping, co-precipitation |
