  • Lithium ion battery including nano-crystalline graphene electrode
    Patent number: 11158849
    Abstract: Provided are lithium ion batteries including a nano-crystalline graphene electrode. The lithium ion battery includes a cathode on a cathode current collector, an electrolyte layer on the cathode, an anode on the electrolyte layer, and an anode current collector on the anode. The anode and the cathode include a plurality of grains having a size in a range from about 5 nm to about 100 nm. The cathode has a double bonded structure in which a carbon of the graphene is combined with oxygen.
