  • Positive Electrode Active Material for Lithium Secondary Battery and Positive Electrode Material Mixture, Positive Electrode, Lithium Secondary Battery Comprising the Same
    Publication number: 20240105934
    Abstract: A positive electrode active material for a lithium secondary battery has a mixture of microparticles having a predetermined average particle size (D50) and macroparticles having a larger average particle size (D50) than the microparticles. The microparticles have the average particle size (D50) of 1 to 10 ?m and are at least one selected from the group consisting of particles having a carbon material coating layer on all or part of a surface of primary macroparticles having an average particle size (D50) of 1 ?m or more, particles having a carbon material coating layer on all or part of a surface of secondary particles formed by agglomeration of the primary macroparticles, and a mixture thereof. The macroparticles are secondary particles having an average particle size (D50) of 5 to 20 ?m formed by agglomeration of primary microparticles having a smaller average particle size (D50) than the primary macroparticles.

  • Tires with resonators for noise reduction
    Patent number: 11794527
    Abstract: A tire with a resonator for noise reduction includes: a main groove unit which has a plurality of main grooves formed to extend along a circumferential direction of the tire; a resonance unit which is formed between a pair of the main grooves; a neck unit which is provided to communicate the resonance unit with one of the pair of main grooves; and a cuff unit which is provided to connect the resonance unit and the other of the pair of main grooves.
