abstract = {Phosphate lithium ion conductors are outstanding
electrolyte materials for solid-state lithium batteries. As
polycrystalline ceramics, they have to be sintered at high
temperatures. Lithium tungstate Li 2 WO 4 (LWO) is reported
for the first time as an effective sintering aid to reduce
the sintering temperature for one of the most common
solid-state lithium ion conductors, Li 1.5 Al 0.5 Ti 1.5 (PO
4 ) 3 (LATP). While densification of LATP without sintering
aids requires temperatures of at least 950°C to obtain a
relative density of $90\%,$ here relative densities of
$90-95\%$ are achieved even at 775°C when 5 $wt.\%$ of LWO
is added. At 800°C the LATP containing 5 - 7 $wt.\%$ LWO
densifies to a relative density of $97.2\%.$ The ionic
conductivity of LWO containing LATP is generally higher than
that of pure LATP sintered at the same temperature. LATP
containing 7 $wt.\%$ LWO shows high ionic conductivity of
4.4 × 10 -4 S/cm after sintering at 825°C. A significant
reduction in sintering temperature, an increase in density
and in the ionic conductivity of LATP as well as its non
toxicity render LWO a very promising sintering aid for the
development of LATP-based solid state batteries.},
