Li-Ion Conductive LiAlTi(PO) (LATP) Solid Electrolyte Prepared by Cold Sintering Process with Various Sintering Additives.

The density, microstructure, and ionic conductivity of solid electrolyte LiAlTi(PO) (LATP) ceramics prepared by cold sintering using liquid and solid sintering additives are studied. The effects of both liquid (water and water solutions of acetic acid and lithium hydroxide) and solid (lithium acetate) additives on densification are investigated. The properties of cold-sintered LATP are compared to those of conventionally sintered LATP.
