description The invention relates to a method for producing an electrode (E) for an electrochemical cell, in particular for a lithium cell. In order to produce a homogeneous mixture allowing the time-saving, cost-effective production, for example by dry coating, of an electrode (E) with improved properties and/or with a layer thickness significantly greater than 100 μm, for example for vehicle batteries, in particular for electric and/or hybrid vehicles, in said method at least one binder (B) and at least one particulate fibrillation auxiliary agent (F) are mixed in a mixing process with a high shear load, the at least one binder (B) being fibrillated (fB), and at least one electrode component (E1) is then added to the at least one fibrillated binder (B) in a mixing process with a low shear load. The invention also relates to an electrode (E) produced in this manner and to an electrochemical cell equipped with an electrode (E) of this type.
