## Description

- description: The surface modification of lithium phosphate on lithium alumina titanium
    phosphate (LATP) by a wet chemical method densified the LATP to over 90% at a
    sintering temperature of 800 °C. This temperature was approximately 300 °C lower
    than that of LATP without additives. Densification of LATP with lithium phosphate
    significantly progressed from 700°C to 800°C, and endothermic peaks corresponding
    to its melting were found in a similar temperature range, suggesting that the
    densification mechanism would be due to liquid phase sintering. The liquid phase
    of Li3PO4 is produced by a multi-step thermal decomposition involving the reaction
    with LATP. The sintered LATP with lithium phosphate showed a density of about
    90% and the highest ionic conductivity of 3.5×10-4 S/cm at 25 °C, suggesting an
    excellent Li ion conducting, solid electrolyte material.
