Abstract: A freestanding laminate includes a separator and an anode layer. The anode layer includes an electrically conductive carbon active material including particular amounts of an activated carbon; a binder; and an electrically conductive filler. The anode layer is in direct physical contact with a first side of the separator. The freestanding laminate is particularly useful for use in various energy storage devices.
