This study investigates the effect of chelating agents on the properties of LATP solid-state electrolytes (SSEs) synthesized by the sol-gel method. Three different chelating agents are employed: Citric acid, Acetylacetone, and Ethylenediaminetetraacetic acid (EDTA). The thermal, structural, and electrochemical properties of the LATP samples are investigated and evaluated their performance in solid-state batteries. The chelating agents significantly impact the thermal behavior, phase formation, and microstructure of LATP SSEs due to their intrinsic chemical bonding property. LATP using citric acid (c-LATP) exhibits the small grain size of about 2 μm and the highest density of 2.8 g/cm<sup>3</sup>. The Li//c-LATP//Li cell presents the most stable voltage profile with the lowest overpotential resulting from good ionic conductivity (1.03 × 10<sup>−3</sup> S/cm). In addition, The Li//c-LATP//LFP battery shows the highest capacity retention rate (81 %) after 100 cycles and excellent rate performance. These results highlight the importance of chelating agent selection in the sol-gel synthesis of LATP for optimizing its properties and achieving high performance of all-solid-state batteries.</div></div>","PeriodicalId":267,"journal":{"name":"Ceramics International","volume":"51 8","pages":"Pages 10502-10509"},"PeriodicalIF":5.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143594224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The anodization process utilized both aqueous and organic fluoride-containing solutions. The substrates examined included Ti-53Nb with low and high interstitial O/N content, Ti-13Nb-13Zr, and Ti-6Al-4V alloys. These alloy substrates were fabricated using powder bed fusion techniques. The characterization of these nanostructures was carried out using scanning electron microscopy, grazing-incidence X-ray diffraction, and X-ray photoelectron spectroscopy. The nanostructures presented smaller inner diameters and greater lengths when grown in the organic electrolyte. The α-phase was stabilized only in the Ti-53Nb alloy with high O/N content, which led to a disruption in the alloy's nanostructure arrangement. The difference in the interstitial contents in Ti-53Nb alloy did not change the chemical composition of the nanostructured layer. For the α+β Ti alloys, a nanostructured arrangement was observed perpendicular to the nanostructure lateral surface of the phase with a higher growth rate. The experimental results indicate that the nanostructure growth rate strongly depends on the chemical composition of the phases present in the microstructure.

To better show the microstructural evolution mechanisms during the grinding process, the researchers used various complementary characterization techniques to observe the phase composition, texture, microstructure, and mechanical properties of specimens before and after grinding. The results indicated that the surface of the ground specimens formed a gradient microstructure, with gradient variations in dislocation density, grain size, and grain boundary distribution. High-density dislocations and amorphization dominated the plastic deformation of the specimens. Dislocations, stacking faults, and lattice distortions were observed at the grain boundaries of the high-entropy alloy (HEA), which are prerequisites for amorphization. Because HEAs were added, the defects in the ground high-entropy cemented carbide were significantly fewer than those in traditional hard alloys. In addition, nanoindentation experiments indicated that surface defects and grains sliding together contributed to a slight degradation in mechanical properties after grinding.
