Abstract
An apparatus for forming an electrode film mixture can have a first source including a polymer dispersion comprising a liquid and a polymer, a second source including a second component of the electrode film mixture, and a fluidized bed coating apparatus including a first inlet configured to receive from the first source the dispersion, and a second inlet configured to receive from the second source the second component.
Claims26
A system for forming an energy storage device electrode film, comprising:
- a first source comprising a polymer dispersion, the polymer dispersion comprising a liquid and a polymer, wherein the polymer is a first component of an energy storage device electrode film mixture;
- a second source comprising a second component of the energy storage device electrode film mixture;
- a fluidized bed coating apparatus comprising a fluidized bed volume, a first inlet and a second inlet, the fluidized bed coating apparatus configured to receive the polymer dispersion from the first source through the first inlet into the fluidized bed volume, and the second component from the second source through the second inlet into the fluidized bed volume, and to form the electrode film mixture within the fluidized bed volume, wherein the first and second sources are different sources;
- and
- a calender apparatus configured to receive the electrode film mixture to form an electrode film;
- wherein the system does not comprise an electrode film drying apparatus.
