Investigation of the effects of pulse width modulation on the laser sintering of LATP for all-solid-state batteries

Abstract Inorganic solid electrolytes are the most important component for realizing all-solid-state batteries with lithium metal anodes and enable safe battery cells high energy densities. Their synthesis processing subject of current research, especially NASICON-type Li 1+x AlxTi 2-x (PO 4 ) 3 (LATP). Herein, ability sintering electro-magnetic irradiation is investigated correlated different properties prepared LATP pellets. First all, an infrared camera records temperature surface during treatment. Second, effect pulse fluence in terms topology morphology Here, arithmetic roughness Ra main parameter. Then, depth radiation interaction pellet measured. The focus this paper on widths laser sources, therefore, similar hatch overlap ensure equivalent areal input both cases. As a summarized result, treatment shorter width generates peak powers, resulting higher temperatures, rougher surfaces affecting deeper layers pellets compared to longer width. On contrary, excessive power leads ablation material up destruction.
