A recognition method for a battery cell package and a structure thereof includes: a) providing a plurality of battery cells arranged in a stack or in a wrapped roll; b) providing a tape, an isolation film or an electrode slat having a shape recognition structure; c) providing a packaging bag; d) placing the tape, the isolation film or the electrode slat at an outer layer of the battery cells; and e) placing the plurality of battery cells into the packaging bag and drawing an air out of the packaging bag such that an outer surface of the packaging bag reveals the shape recognition structure of the tape, the isolation film or the electrode slat. Therefore, the specifications and models of the battery cell packages can be determined with ease to facilitate the categorization and storage of the battery cell packages.
