Abstract
An energy storage device can include a cathode, an anode, and a separator between the cathode and the anode. At least one of the electrodes can include an electrode film prepared by a dry process. The electrode film, the electrode and/or the separator can comprise a salt, improved porosity, increased density, be prelithiated, and/or a foam. An energy storage device can include a dry composite solid polymer electrolyte (SPE) film. Process and apparatuses used for fabricating the composite solid polymer electrolyte film, electrode and/or electrode film are also described.
Claims11
A dry composite solid polymer electrolyte (SPE) film of an energy storage device, comprising:
- a dry ion conducting polymer;
- a dry lithium source;
- a dry binder comprising a fibrillized binder;
- an ion conducting medium;
- and
- a dry filler material,
- wherein the SPE film is free-standing and absent of solvent residue.
