Li-CO2 batteries have high energy density by using lithium metal as an anode, and are very promising and attractive in the future battery market. However, the main task of Li-CO2 batteries is the safety and longevity of Lithium metal. In this study, a Li-CO2 battery with a stable and reduced interfacial resistance was studied using a gel polymer electrolyte and a solid electrolyte. It was measured in a CO2 atmosphere. LATP pellets have high electrochemical stability and help lithium ions as a solid electrolyte. However, since solid electrolytes generate high interfacial resistance between lithium metals, we reduced interfacial resistance and increased the stability of Li-CO2 cells by using PAN gel polymer electrolyte in the middle. The structure and characteristics of the battery were confirmed through measurements such as Electrochemistry measurement, X-ray diffraction (XRD), and Field Emission Scanning Electron Microscope (FE-SEM).KEYWORDSLapt ceramic, pan gel polymer electrolyte, li-co2 battery, lithium metal |
