  • Patent number: 11978901
    Abstract: A cathode for a lithium secondary battery includes a cathode current collector, and a cathode active material layer formed on the cathode current collector. The cathode active material layer includes a cathode active material and a conductive material ID/IG is in a range from 0.5 to 1.25 in a Raman spectrum of the cathode active material layer. The cathode active material includes lithium metal oxide particles containing nickel and manganese and having a content of cobalt of less than 2 mol % among all elements except for lithium and oxygen.

  • Patent number: 9651670
    Abstract: A method and apparatus for improving anti-jamming performance are provided. A threshold value level estimated in a GPS (global positioning system) receiver RF/IF stage, a threshold value weight, a median value of a median value of a 2˜8 MHz bandwidth is estimated as a threshold value with respect to a frequency component exceeding the estimated threshold value level, and an adjustable K-median threshold scheme is provided in a multi-jamming environment.
