Abstract:
An electrode for an energy storage device includes carbon black particles having (a) a Brunauer-Emmett-Teller (BET) surface area ranging from 70 to 120 m2/g; (b) an oil absorption number (OAN) ranging from 180 to 310 mL/100 g; (c) a surface energy less than or equal to 15 mJ/m2; and (d) either an La crystallite size less than or equal to 29 Å, or a primary particle size less than or equal to 24 nm.
