Abstract
An electrode includes an electrode composition having carbon nanotubes; carbon black particles having a Brunauer-Emmett-Teller (BET) surface area greater than 90 m2/g, and an oil adsorption number (OAN) greater than 150 mL/100g, wherein the ratio of the carbon nanotubes to the carbon black particles ranges from 3:1 to 0.25:1 by weight; and an electroactive material selected from lithium nickel cobalt manganese oxide or lithium nickel cobalt aluminum oxide; and a current collector contacting the electrode composition. The total concentration of the carbon nanotubes and the carbon black particles is equal to or less than 3 wt % of the electrode composition.
