Properties of Li1.3Al0.3Ti1.7(PO4)3 Lithium-Conducting Ceramics Synthesized by Spark Plasma Sintering

Results on the synthesis of lithium-conducting ceramics Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 by the method of spark plasma sintering (SPS) are presented. In the first stage, the monophase Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 solid-electrolyte powder is synthesized from the nitrate-peroxide precursor. Its subseq...

Description
Summary:Results on the synthesis of lithium-conducting ceramics Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 by the method of spark plasma sintering (SPS) are presented. In the first stage, the monophase Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 solid-electrolyte powder is synthesized from the nitrate-peroxide precursor. Its subsequent consolidation by the SPS method provides the formation of ceramics with the high Li-ionic conductivity and the density on the level of 97–98%. The microstructure and the electrochemical properties of the Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 ceramics are studied.
