  • Solventless Quantum Dot Composition, Preparation Method Therefor, And Cured Film, Color Filter And Display Device Which Comprise Same
    Publication number: 20240101848
    Abstract: A quantum dot composition, a preparation method therefor, and a cured film, a color filter and a display device that comprise the same are described. Specifically, a solventless quantum dot composition comprises quantum dots, which are surface-treated with two types of ligands. As a result, the quantum dot composition exhibits low viscosity, excellent optical properties, and high storage stability.

  • Negative electrode comprising mesh-type current collector, lithium secondary battery comprising the same, and manufacturing method thereof
    Patent number: 10686193
    Abstract: The present disclosure relates to a negative electrode for a lithium secondary battery comprising a mesh-type current collector and a lithium thin film, and in particular, to a negative electrode in which a lithium thin film is inserted to an opening of a current collector and empty space is formed, a lithium secondary battery comprising the same, and a manufacturing method thereof. The present disclosure is capable of enhancing safety of the lithium secondary battery by preventing lithium dendrite growth. In addition, the present disclosure is capable of preventing stripping of the negative electrode current collector and the lithium thin film while charging and discharging the battery since adhesion efficiency increases between the negative electrode and the current collector.
