COMPOSITIONS CONTAINING CARBON BLACK AND GRAPHENES ADDITIVES, RELATED ELECTRODES AND RELATED BATTERIES

Abstract:

An electrode includes an electrode composition having graphenes; carbon black particles having a Brunauer-Emmett-Teller (BET) surface area greater than 90 m.sup.2/g, and an oil adsorption number (OAN) greater than 150 mL/100 g, wherein the ratio of the carbon black particles to the graphenes ranges from 3:1 to 6:1 by weight; and an electroactive material selected from the group consisting of lithium nickel cobalt manganese oxide and lithium nickel cobalt aluminum oxide, wherein the total concentration of the graphenes and the carbon black particles is equal to or less than 2 wt % of the electrode composition; and a current collector contacting the electrode composition.
