Abstract: A method for lithiation of an electrode includes providing an electrode to be lithiated, providing a piece of lithium metal with predetermined weight attached to a conductive material, attaching the conductive material to a current collector of the electrode to be lithiated or to a metal tab connected to or from the electrode to be lithiated, placing the electrode to be lithiated, the piece of lithium, and the conductive material in a container, and filling the container with an electrolyte containing a lithium salt.

Abstract: An apparatus for manufacturing an electrode for an energy storage device includes at least one laminator for simultaneously laminating two free-standing electrode films on opposite sides of a current collector and a pair of mill lines operable to produce, respectively, the two films and to feed the two films simultaneously to the laminator. Each mill line may have at least one press including working rolls arranged horizontally for pressing a powder mixture into a respective one of the films and at least one press including working rolls (typically arranged vertically) for reducing the thickness of the respective film. The apparatus may include a mill line expansion module that is insertable into a mill line and has at least one additional press including working rolls for reducing the thickness and controlling other key parameters of the respective film. Films may have elongation below 4% and tensile strength below 250 kPa.

Abstract: A method of manufacturing a free-standing electrode film for an electrode of an energy storage device includes providing a powder mixture of at least one electrode active material and at least one fibrillizable binder and feeding the powder mixture to a mill line including one or more presses. At least one press may include a pair of opposing working rolls and a backing roll associated with each working roll. An apparatus for manufacturing a free-standing electrode film includes a mill line including at least one press having a pair of opposing working rolls and a backing roll associated with each working roll, a barrel of at least one of the backing rolls having a diameter that is at least 1.5 times a diameter of a barrel of the associated working roll, the barrels of the opposing working rolls each having a total indicated runout (TIR) of less than 5 ?m.

Abstract: A method of manufacturing a free-standing electrode film includes preparing a mixture including an electrode active material, a conductive material, and a binder, heating the mixture to 70° C. or higher, subjecting the mixture to a shear force, and, after the mixture has been subjected to the shear force, pressing the mixture into a free-standing film. The method may further include adding a solvent to the mixture. A resulting free-standing electrode film may include an amount of binder less than 4% by weight.
