The battery module includes: a first-type battery cell and a second-type battery cell, which are connected in series, the first-type battery cell and the second-type battery cell are battery cells of different chemical system, and the volume energy density of the first-type battery cell is less than the volume energy density of the second-type battery cell; and the capacity Cap1 of the first-type battery cell is greater than the capacity Cap2 of the second-type battery cell. While ensuring the safety performance of the battery module, the service life and the energy throughput of the battery module are effectively improved.",
