  • Publication number: 20250062360
    Abstract: A binder includes composite particles with a polytetrafluoroethylene structure coated with an acrylic polymer. The binder can be for a lithium secondary battery according to one embodiment of the present invention, and not only can solve problems such as agglomeration that can occur when handling conventional binders, but also has excellent physical properties such as low thickness deviation and high tensile strength when manufacturing electrodes. In addition, a battery with these electrodes has improved performance, such as improved capacity retention rate.

  • Patent number: 12219810
    Abstract: The display device includes a substrate including a plurality of pixel areas; and a pixel in each of the plurality of pixel areas. The pixel may include a pixel circuit layer on the substrate and including at least one transistor; a first electrode on the pixel circuit layer and electrically connected to the transistor; a plurality of light emitting elements on the first electrode and electrically connected to the first electrode; a second electrode on the plurality of light emitting elements; and a light blocking pattern on the second electrode and including a plurality of openings corresponding to each of the plurality of light emitting elements. Here, each of the plurality of pixel areas may include an emission area corresponding to each of the plurality of openings and a non-emission area excluding the emission area.

  • Patent number: 7797781
    Abstract: A robot mechanism adopts a dry cleaning method to clean the surface of live-line insulators without using water and can perform cleaning and inspection of the surface of the live-line insulators while automatically moving along an insulator string. The robot mechanism includes a main unit having upper and lower wing frames connected with each other by a connecting bracket to surround the insulator string, a cleaning unit disposed between the upper and lower wing frames and including a base frame to perform dry cleaning with a rotational brush and a CM guide, a lift unit including a clamp and a ball-bearing screw to move the main unit up or down, and an inspection unit to electrically inspect the insulators; and a coupling unit to couple a pair of the main units to allow the pair of main units to move along a tension insulator string or a suspension insulator string.
