Abstract: A method for fabricating an electrode for a battery cell includes supplying a first electrode film from a first roll. The first electrode film comprises an active material for exchanging lithium ions and a binder. The method includes treating a first side of the first electrode film using a first plasma treatment system; supplying a current collector, and heating and pressing the first side of the first electrode film to a first side of the current collector together using first and second rollers.
