Abstract Scope |
Though solid-state electrolytes offer improved safety over flammable liquid electrolytes, the room temperature ionic conductivity hinders utilization. The ionic conductivity of solid-state electrolyte Li2O-Al2O3-TiO2-P2O5 (LATP) is limited by the formation of secondary phase particles in conjunction with vaporization of volatile elements due to thermal decomposition that occurs during high temperature processing. In the additive manufacturing process, laser powder bed fusion (L-PBF), the processing temperatures are determined by laser process parameters, such as laser scan speed. In this study, the influence of the laser process parameter, laser scan speed, on the amount of materials vaporization is experimentally determined by ex-situ evaluation of the diffusion coefficient and changes in the chemical composition of bulk LATP samples prepared using L-PBF. Findings indicate that the L-PBF laser scan speed influences processing temperatures and materials vaporization leading to differences in diffusivity of LATP. |
