| Abstract: | The article focuses on the development of solid-state lithium-ion batteries using lithium aluminum titanium phosphate (LATP) as a solid electrolyte, emphasizing the cold sintering process as a novel method for enhancing densification and ionic conductivity. Cold sintering allows for the densification of LATP ceramics at temperatures below 280 °C, achieving relative densities over 90% and ionic conductivities up to 1.26 × 10−5 S/cm when using liquid additives like water and acetic acid. The study highlights the importance of sintering additives and temperature optimization in achieving high ionic conductivity, while also addressing the formation of secondary phases and microcracks that can hinder performance. The findings suggest that cold sintering could be a viable approach for producing solid electrolytes for all-solid-state batteries, warranting further investigation into improving ionic conductivity and understanding phase formation during the process.
