  • Negative electrode for rechargeable lithium battery and rechargeable lithium battery including same
    Patent number: 10147939
    Abstract: A negative electrode for a rechargeable lithium battery includes a negative active material including a titanium-containing oxide and amorphous carbon. The titanium-containing oxide is present in a larger amount than the amorphous carbon.
    Type: Grant
    Filed: February 21, 2017
    Date of Patent: December 4, 2018
    Assignee: Samsung SDI Co., Ltd.
    Inventors: Sun-Il Park, Young-Kee Kim, Joon-Kil Son, Soojeong Lee
  • Rechargeable lithium battery with controlled particle size ratio of activated carbon to positive active material
    Patent number: 10074848
    Abstract: A rechargeable lithium battery that includes: a negative electrode including a negative active material, and a positive electrode including a positive active material and activated carbon. When the positive active material includes a lithium iron phosphate-based compound, the average particle diameter of the activated carbon is greater than or equal to about 1000% and less than or equal to about 3000% of the average particle diameter of the positive active material.
