    Professor Yan Yu's team at USTC utilized the CIQTEK Scanning Electron Microscope SEM3200 to study the post-cycling morphology. It developed amorphous carbon with controllable defects as a candidate material for an artificial interface layer balancing potassiophilicity and catalytic activity.   The research team prepared a series of carbon materials with different degrees of defects (designated as SC-X, where X represents the carbonization temperature) by regulating the carbonization temperature. The study found that SC-800 with excessive defects caused substantial electrolyte decomposition, resulting in an uneven SEI film and shortened cycle life. SC-2300, with the fewest defects, had insufficient affinity for potassium and easily induced potassium dendritic growth. SC-1600, which possessed a locally ordered carbon layer, exhibited an optimized defect structure, achieving the best balance between potassiophilicity and catalytic activity. It could regulate the electrolyte decomposition and form a dense and uniform SEI film.   The experimental results demonstrated that SC-1600@K exhibited long-term cycle stability for up to 2000 hours under a current density of 0.5 mA cm-2 and a capacity of 0.5 mAh cm-2. Even under higher current density (1 mA cm-2) and capacity (1 mAh cm-2), it maintained excellent electrochemical performance with stable cycles exceeding 1300 hours. In full-cell testing, when paired with a PTCDA positive electrode, it maintained 78% capacity retention after 1500 cycles at a current density of 1 A/g, demonstrating outstanding cycle stability.   This research, titled "Balancing Potassiophilicity and Catalytic Activity of Artificial Interface Layer for Dendrite-Free Sodium/Potassium Metal Batteries," was published in Advanced Materials. Figure 1: The microstructure analysis results of carbon samples (SC-800, SC-1600, and SC-2300) prepared at different carbonization temperatures are presented. Through techniques such as X-ray diffraction (XRD), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), and wide-angle X-ray scattering (WAXS), the crystal structure, defect level, and oxygen and nitrogen doping of these samples were analyzed. The results showed that as the carbonization temperature increased, the defects in the carbon materials gradually decreased, and the crystal structure became more orderly.   Figure 2: The current density distribution during potassium metal growth on different composite negative electrodes was analyzed using finite element simulation. The simulation results showed that the SC-1600@K composite electrode exhibited a uniform current distribution during potassium deposition, which helped suppress dendritic growth effectively. Additionally, the Young's modulus of the SEI layer was measured using atomic force microscopy (AFM), and the results showed that the SEI layer on the SC-1600@K electrode had a higher modulus, indicating its stronger firmness and...
