Abstract:
Methods for manufacturing intermittently coated dry electrodes for energy storage devices and energy storage devices including the intermittently coated dry electrodes are disclosed. In one embodiment, the method includes providing a metal layer and providing an electrochemically active free-standing film formed of a dry active material. The method also includes combining the electrochemically active free-standing film and the metal layer to form a combined layer. The method further includes removing a portion of the electrochemically active free-standing film from the combined layer so that the electrochemically active free-standing film is intermittently formed on the metal layer in a longitudinal direction of the metal layer.
