METHODS AND APPARATUSES FOR ENERGY STORAGE DEVICE ELECTRODE FABRICATION

Apparatuses and methods for forming an electrode film mixture are described. An apparatus for forming an electrode film mixture can have a first source including a solution comprising a polymer, for example, polytetrafluoroethylene and a critical or supercritical fluid, for example, supercritical carbon dioxide, a second source including a second component of the electrode film mixture, a mixer configured to receive the solution and the second component and to form a slurry comprising the solution and the second component. The apparatus can include a decompressor configured to receive the slurry and decompress the slurry to vaporize the critical or supercritical fluid and precipitate dry polymer.
