NASICON-type solid electrolytes are an exciting candidate within ceramic electrolytes due to their high ionic conductivity and low moisture sensitivity, making them a prime candidate for pure oxidic and hybrid ceramic-in-polymer composite electrolytes. Here, we report on producing pure and Y-doped Lithium Aluminum Titanium Phosphate (LATP) nanoparticles by spray-flame synthesis. The as-synthesized samples consist of an amorphous component and anatase-TiO2 crystalline particles. Brief annealing at 750\u20131000 \u00b0C for one hour was sufficient to achieve the desired phase while maintaining the material\u2019s sub-micrometer scale. Rietveld analysis of X-Ray diffraction data demonstrated that the crystal volume increases with Y doping. At the same time, with high Y incorporation, a segregation of the YPO4 phase was observed in addition to the desired LATP phase. Another impurity phase, LiTiOPO4, was observed besides YPO4 and, with higher calcination temperature (1000 \u00b0C), the phase fraction for both impurities also increased. The ionic conductivity increased with Y incorporation from 0.1 mS\/cm at room temperature in the undoped sample to 0.84 mS\/cm in the case of LAY0.1TP, which makes these materials\u2014especially considering the comparatively low sintering temperature\u2014highly interesting for applications in the field of solid-state batteries.<\/jats:p>","DOI":"10.3390\/nano15010042","type":"journal-article","created":{"date-parts":[[2024,12,31]],"date-time":"2024-12-31T13:26:25Z","timestamp":1735651585000},"page":"42","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Spray-Flame Synthesis (SFS) and Characterization of Li1.3Al0.3\u2212xYxTi1.7(PO4)3 [LA(Y)TP] Solid Electrolytes"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6581-576X","authenticated-orcid":false,"given":"Md Yusuf","family":"Ali","sequence":"first","affiliation":[{"name":"Institute for Energy and Materials Processes\u2014Reactive Fluids, University of Duisburg-Essen, 47057 Duisburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hans","family":"Orthner","sequence":"additional","affiliation":[{"name":"Institute for Energy and Materials Processes\u2014Reactive Fluids, University of Duisburg-Essen, 47057 Duisburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8487-9937","authenticated-orcid":false,"given":"Hartmut","family":"Wiggers","sequence":"additional","affiliation":[{"name":"Institute for Energy and Materials Processes\u2014Reactive Fluids, University of Duisburg-Essen, 47057 Duisburg, Germany"},{"name":"Center for Nanointegration Duisburg-Essen (CENIDE), 47057 Duisburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,12,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1195","DOI":"10.1002\/inf2.12222","article-title":"Progress and perspective of Li1+xAlxTi2\u2212x(PO4)3 ceramic electrolyte in lithium batteries","volume":"3","author":"Yang","year":"2021","journal-title":"InfoMat"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1507","DOI":"10.1021\/acsami.6b13224","article-title":"Are All-Solid-State Lithium-Ion Batteries Really Safe?\u2013Verification by Differential Scanning Calorimetry with an All-Inclusive Microcell","volume":"9","author":"Inoue","year":"2017","journal-title":"ACS Appl.
