Li1+xAlxTi2-x(PO4)3 (LATP) is a highly promising solid-state electrolyte, known for its high lithium-ion conductivity and stability at room temperature. This study successfully prepared LATP-LT composite solid-state electrolytes by combining LATP with Li2O-TeO2 (LT) glass, utilizing the molten state of the glass at high temperatures. The investigation focused on the effects of different ratios and sintering conditions on the performance of the LATP-LT composites. Results indicate that an appropriate amount of LT enhances the material's sinterability, facilitating continuous lithium-ion conductivity while inhibiting the diffusion of lithium dendrites within the pores. The LATP-LT composite solid electrolyte achieved an ionic conductivity of 1.81×10-4 S/cm at room temperature. Thus, selecting an optimal concentration of LT can serve as a breakthrough in the development of all-solid-state lithium-ion batteries, advancing the field of solid-state electrolytes.
