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.

Abstract: A method of manufacturing a free-standing electrode film includes preparing a mixture including an electrode active material, a binder, and an additive solution or conductive paste, the additive solution or conductive paste being in an amount less than 5% by weight of the mixture and including a polymer additive and a liquid carrier, as well as a conductive material in the case of a conductive paste. The mixture may have total solid contents greater than 95% by weight. Preparing the mixture may include mixing the additive solution or conductive paste with the electrode active material to lubricate the electrode active material and subsequently adding and mixing in the binder. The method may further include 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.
