Abstract: A battery pack and an electric vehicle are provided. The battery pack (200) includes a battery sequence (201). The battery sequence (201) includes multiple cells (100). A thickness of each cell (100) extends along a first direction. The multiple cells (100) are arranged in sequence along the first direction to form the battery sequence (201). At least one of the cells (100) includes a metal shell (101) and an electrode core (102) packaged in the metal shell (101). An air pressure inside the metal shell (101) is lower than an air pressure outside the metal shell (101). A gap is provided between at least two adjacent cells (100). A ratio of the gap to the thickness of the cell (100) ranges from 0.001 to 0.15.
