A roll map of an electrode coating process includes a roll map bar and a representation part. The roll map bar is displayed on a screen in synchronization with movement of an electrode between an unwinder and a rewinder while being coated with an electrode slurry in a roll-to-roll state. The roll map bar is displayed in the form of a bar by simulating the electrode in the roll-to-roll state. The representation part is configured to visually show either one of or both quality-related and defect-related acquired data associated with the electrode coating process. The acquired data is shown at a certain location on the roll map bar corresponding to a location in the electrode at which the data is measured. A roll map of an electrode coating process is generated by a process. A roll map of an electrode coating process is generated by a system.
