  • Negative Electrode for Lithium Secondary Battery with Improved Safety or Internal Short, Lithium Secondary Battery Containing the Same and Lithium Secondary Battery System Therefor
    Publication number: 20240421287
    Abstract: A negative electrode for a lithium secondary battery includes: a negative electrode active layer provided on at least one surface of a negative electrode current collector, and including a negative electrode active material; and a coating layer disposed on the negative electrode active layer. The coating layer contains silicon-containing particles, aluminum-containing particles and a dispersant, and a volume resistance of the coating layer is about 1.0×10?4 ?·cm to 1.0 ?·cm.

  • Lithium Secondary Battery with Improved Safety of Internal Short and Lithium Secondary Battery System Therefor
    Publication number: 20240291048
    Abstract: A lithium secondary battery includes: a positive electrode, a negative electrode, and a separator disposed between the positive electrode and the negative electrode. In the negative electrode, a negative electrode active layer containing a carbon-based negative electrode active material and a coating layer containing silicon-containing particles are sequentially located on a negative electrode current collector, and a volume resistance of the negative electrode is about 6.0×10?3 ?·cm to 1.0 ?·cm.

  • Method for making optical fiber preform having ultimately low pmd through improvement of ovality
    Publication number: 20050103057
    Abstract: A method for making an optical fiber preform having an ultimately low PMD (Polarization Mode Dispersion) through improvement of ovality is provided. This method has several collapse steps for collapsing an optical fiber preform having a clad/core deposition layer formed in a preform tube in which a rate of collapse is 0.01-0.06 mm/min at each collapsing step. By using this method, ovality and PMD of the optical fiber preform may be improved.
