A novel, boltless and easily assembled zinc–air battery configuration is developed to compare with the conventional configuration commonly used in most academic studies. A zinc–air battery with a boltless configuration can fundamentally avoid the man-made leakage risk by sealing the internal environment via mechanical fasteners on the battery body and enhancing the cell capacity by modifying the battery configuration. The volume energy density and the mass energy density of zinc–air battery stacks with five zinc–air batteries in series are 117.3 Wh L−1 and 68.0 Wh kg−1, respectively, both exceeding those of commercial lead-acid batteries. This study simulates the static and dynamic application of zinc–air battery stacks as a power supply for an electric motorcycle and a single flow battery energy storage unit, showing high commercial application potential in mobile power supply and scale energy storage.
