Abstract: A method of patterning a substrate includes applying a first potential to a spray nozzle, applying a second potential to at least one first cell electrode among a plurality of cell electrodes on a first surface of the substrate, applying a third potential to at least one second cell electrode excluding the at least one first cell electrode among the cell electrodes, and applying a fourth potential to a second surface that is opposite to the first surface of the substrate.

Abstract: A secondary battery includes an electrode assembly including a negative electrode layer, a separation film and a positive electrode layer arranged in a first direction; and a case in which the electrode assembly is accommodated, the case including a first pressing portion which faces a first side surface of the electrode assembly accommodated in the case and applies a first pressing force to the electrode assembly along the first direction. The first pressing portion includes: a first surface facing the first side surface of the electrode assembly accommodated in the case; and a second surface opposite to the first surface and exposed outside the case, the second surface of the first pressing portion including a plurality of first curved grooves arranged along the first side surface of the electrode assembly accommodated in the case and lengthwise extending in a second direction crossing the first direction.
