摘要： A method of producing a battery electrode includes dispensing a pasty coating material by a coating installation onto a surface of a moving substrate, wherein the coating installation includes a switchable slotted valve, a feed device that feeds the pasty coating material to the slotted valve, and a slotted nozzle that adjoins the slotted valve and dispenses the pasty coating material onto the surface to be coated therewith; the switchable slotted valve includes a valve bore incorporated into a valve basic body, oriented in a valve direction of extent and having an inner circumferential surface, a feed duct arranged in a region of the inner circumferential surface of the valve bore and opens into the valve bore, a nozzle duct arranged in the region of the inner circumferential surface, a valve sleeve arranged in the valve bore, and a control rod arranged in the valve bore.
