Study of LiNi0.6Co0.2Mn0.2O2 coated with the Li2ZrO3 nanolayer in all-solid-state lithium ion batteries |
초록 |
LiNi0.6Co0.2Mn0.2O2(NCM) is covered with Li2ZrO3 nanolayer. Li2ZrO3 can block the side reaction of interface between oxide-based cathode and sulfide-based electrolyte due to the higher stability and lower interfatial resistance. Coating of Li2ZrO3 on NCM was obtained by sol-gel technique. NCM and Li and Zr source were dissolved in absolute ethanol separately, and two solution were mixed and evaporated then calcined. Li7P2S11I was used as the solid electrolyte. The structure details of bare and Li2ZrO3-coated NCM were studied by XRD. The morphology of Li2ZrO3-coated NCM and elemental analysis were carried out by SEM and EDS. The thickness of Li2ZrO3 and d-space of Li2ZrO3 and NCM were analyzed by TEM. The electrochemical performances of Li2ZrO3-coated NCM were elucidated from electrochemical impedance spectroscopy, charge-discharge curves, and C-rate performances. |
