The enhancement of the high-rate capability of solid-state Lithium Batteries by nanoscale interfacial modification, was analyzed. The surface of LiCoO2 with Li4Ti5O12 was coated by spray coating. When the sulfide electrolytes were in contact with the oxide electrodes, the large difference between their chemical potentials make their Li+ ions transfer from the sulfide electrolytes to the oxide electrodes. Electrochemical impedance spectroscopy demonstrated the reduction of the interfacial resistance by the interposition of Li4Ti 5O12. Developed space-charge layer on the sulfide side and very large interfacial resistance improved the high-rate capability of solid-state lithium batteries. This enhancement of capability supports the practical application of solid-state lithium batteries and, hence provides a solution to the safety concerns of lithium batteries.
