Abstract

See full text

A free-standing electrode film may comprise an electrode active material and a composite binder comprising polytetrafluoroethylene (PTFE) and polyvinylpyrrolidone (PVP). An electrode for an energy storage device may comprise a current collector and a film on the current collector, the film including an electrode active material and a composite binder comprising PTFE and PVP. A method of manufacturing a free-standing electrode film may comprise preparing a mixture including an electrode active material and a composite binder, the composite binder comprising PTFE and one or more additional binders selected from the group consisting of PVP, polyvinylidene fluoride (PVDF), polyethylene oxide (PEO), and carboxymethylcellulose (CMC). The method may further comprise adding a solvent to the mixture, subjecting the mixture to a shear force, and, after the solvent has been added and the mixture has been subjected to the shear force, pressing the mixture into a free-standing film.
