Characterization of Lithium-CO2 batteries applied LATP as a solid electrolyte |
초록 |
In this study, we suggest a Li-CO2 battery applied lithium aluminum titanium phosphate (LATP) as a solid electrolyte and a carbon sheet with a multi-walled carbon nanotube (MWCNT). The structural properties of LATP were evaluated using X-ray diffraction (XRD). Ionic conductivity of the LATP pellet was conducted by Electrochemical impedance spectroscopy (EIS), and that of the LATP pellet was ~5.4 ´ 10-4 S / cm. The morphology of carbon cathodes with MWCNT was examined by field emission scanning electron microscope (FESEM). The discharge products for the Li-CO2 electrochemistry were characterized by Raman spectroscopy and X-ray photoelectron spectroscopy (XPS). The electrochemical performance was figured out by a charge-discharge test at a current density of 60 mA / g at the fixed capacity of 600 mAh/g for 30 cycles. This battery’s discharge and charge profiles did not change significantly, which means that the Li-CO2 battery applied a LATP pellet shows high stability.This work provides a new structure of Li-CO2 batteries applied LATP as the solid electrolyte, and this battery could be promising batteries for all-solid-state batteries in the future. |
