    • An apparatus (500) for forming an electrode film mixture can have a first source including a polymer dispersion comprising (501) a liquid and a polymer, a second source including a second component (502) of the electrode film mixture, and a fluidized bed coating apparatus including a first inlet (504) configured to receive from the first source the dispersion, and a second inlet configured to receive from the second source the second component. A corresponding method for preparing an energy storage device electrode film mixture comprises the steps of providing a polymer dispersion to a first inlet of a fluidized bed coating apparatus, the polymer dispersion comprising a liquid and a polymer, wherein the polymer is a first component of an energy storage device electrode film mixture; providing a second component of the energy storage device electrode film mixture to a second inlet of the fluidized bed coating apparatus; vaporizing the liquid portion of the polymer dispersion within the fluidized bed coating apparatus to form a dried polymer; and forming a fluidized bed of the dried polymer and the second component of the electrode mixture within the fluidized bed coating apparatus to form an electrode film mixture.
