  • Patent number: 12206070
    Abstract: A lithium secondary battery including a positive electrode, a negative electrode comprising a negative electrode current collector, and an electrolyte interposed between the positive electrode and negative electrode. The lithium metal is formed on the negative electrode current collector by lithium ions migrating toward the negative electrode current collector after charge. The electrolyte comprises a sacrificial salt having an oxidation potential of 5 V or less with respect to lithium. The lithium secondary battery forms lithium metal while being blocked from the atmosphere, and thereby improves an existing problem caused by high reactivity of lithium metal. By including a sacrificial salt in an electrolyte, lithium consumption caused by an irreversible reaction of a negative electrode is reduced, which may prevent decline in the battery capacity and lifetime properties.

  • Publication number: 20250019827
    Abstract: The present invention relates to a film quality improver, a method of forming a thin film using the film quality improver, a semiconductor substrate fabricated using the method, and a semiconductor device including the semiconductor substrate. The present invention provides a compound having a predetermined structure as a film quality improver. According to the present invention, by forming a shielding area for a molybdenum-based thin film on a substrate, the deposition rate of a molybdenum-based thin film may be reduced, and the growth rate of a thin film may be controlled. Thus, even when forming a thin film using a solid compound on the substrate with a complicated structure at room temperature, step coverage and the thickness uniformity of the thin film may be greatly improved, and corrosion or deterioration may be prevented, thereby improving the crystallinity and electrical properties of a thin film.
