초록

Lithium-ion batteries are widely used in various applications, including electric vehicles and portable electronics, due to their high energy density and long cycle life. The performance of lithium-ion batteries can be improved by using solid electrolytes, in terms of higher safety, stability, and energy density. Li1.5Al0.5Ti1.5(PO4)3 (LATP) is a promising solid electrolyte for all-solid-state lithium batteries due to its high ionic conductivity and excellent stability. However, the ionic conductivity of LATP needs to be improved for commercializing all-solid-state lithium battery systems. In this study, we investigate the microstructures and ionic conductivities of LATP by incorporating B2O3 glass ceramics. The smaller grain size and narrow size distribution were obtained after the introduction of B2O3 in LATP, which is attributed to the B2O3 glass on grain boundaries of LATP. Moreover, higher ionic conductivity can be obtained after B2O3 incorporation, where the optimal composition is 0.1 wt% B2O3 incorporated LATP and the ionic conductivity reaches 8.8×10-5 S/cm, more than 3 times higher value than pristine LATP. More research could be followed for having higher ionic conductivity and density by optimizing the processing conditions. This facile approach for establishing higher ionic conductivity in LATP solid electrolytes could accelerate the commercialization of all-solid-state lithium batteries.
