Binder-conductive additive design for practical sulfurized polyacrylonitrile lithium–sulfur batteries

Abstract Lithium–sulfur batteries are widely regarded as promising next-generation energy storage owing to their high theoretical energy density and the abundance of sulfur. Sulfurized polyacrylonitrile (SPAN) has emerged as a compelling active material, retaining the advantages...

Controlling Grain Growth in Powder Bed Fusion of Yttria‐Stabilized Zirconia Using Femtosecond Lasers: Challenges and Methodological Insights

This study demonstrates binder‐free laser powder bed fusion (PBF‐LB) of 8 mol% yttria‐stabilized zirconia (8YSZ) using a femtosecond laser and a triangular scan strategy that controls heat accumulation by varying scan‐vector length. Laser power (31–52 W), scan speed (100–500 mm s...
