  • Publication number: 20250062322
    Abstract: A silicon-carbon composite of the present invention comprises a lithium silicon composite oxide and carbon, wherein the lithium silicon composite oxide includes silicon particles, silicon oxide, magnesium silicate, and a lithium silicon compound. By comprising two or more carbon layers including a first carbon layer and a second carbon layer, the silicon-carbon composite can improve the performance of a secondary battery, such as slurry stability and initial charge/discharge characteristics, when used as a negative electrode active material of the secondary battery. In addition, the first carbon layer and the second carbon layer of the silicon-carbon composite satisfy specific thickness ranges, and thus, the silicon-carbon composite can further improve the performance of a secondary battery, such as capacity, cycle characteristics, and initial charge/discharge characteristics, when used as a negative electrode active material of the secondary battery.

  • Patent number: 12024423
    Abstract: Provided is a method of fabricating a micro/nanowire having a nanometer- to micrometer-sized diameter at predetermined positions on an object. The method comprises: preparing a micro/nanopipette having a tip with an inner diameter (dpt) which is substantially the same as the diameter of the micro/nanowire to be fabricated; filling the micro/nanopipette with a solution containing a micro/nanowire-forming material; bringing the solution into contact with the object through the tip of the micro/nanopipette; and pulling the micro/nanopipette apart from the object at a pulling speed lower than or equal to a predetermined critical pulling speed (vc) to fabricate a micro/nanowire having substantially the same diameter as the inner diameter of the micro/nanopipette tip (dpt). The critical pulling speed (vc) is defined by a maximum limit of the pulling speed at which the micro/nanowire to be fabricated has the same diameter as the inner diameter of the micro/nanopipette tip (dpt).
