  • Secondary battery separator comprising organic/inorganic composite porous layer, and manufacturing method therefor
    Patent number: 10541399
    Abstract: The present invention relates to a secondary battery separator, and a manufacturing method therefor. The secondary battery separator according to the present invention comprises an organic/inorganic composite porous layer for improving thermal resistance and physical strength, and since the organic/inorganic composite porous layer uses polymer particles as a binder, the secondary battery separator, compared with a separator using a solvent-type binder resin using organic solvents, exhibits excellent permeability.
    Type: Grant
    Filed: October 26, 2015
    Date of Patent: January 21, 2020
    Assignee: LG Chem, Ltd.
    Inventors: Joo-Sung Lee, Ji-Eun Kim, In-Gyoung Yu, Sun-Mi Jin, Da-Kyung Han
  • Electrode tab coated with electrical insulating layer and secondary battery comprising the same
    Patent number: 10454090
    Abstract: An electrode tab coated with an electrical insulating layer according to one aspect of the present disclosure, and a secondary battery comprising the same can provide further enhanced electrical insulating effect.

  • Electrode structure including insulating layer, manufacturing method thereof, and electrochemical device including the electrode
    Patent number: 9793535
    Abstract: Disclosed is a method for manufacturing an electrode structure including (S1) coating and drying a slurry for an electrode active material layer on an electrode current collector placed on a heated bottom surface, (S2) coating and drying a slurry for an insulating layer including inorganic particles, a binder, and a solvent, on a heated roller located at a predetermined distance from the bottom surface, and (S3) transferring the dried slurry for an insulating layer to the dried slurry for an electrode active material layer on the bottom surface, and thermo-compressing the dried slurry for an insulating layer and the dried slurry for an electrode active material layer, to form an insulating layer on an electrode surface.
