Abstract

See full text

A battery module, a battery pack, and an electric apparatus are provided. In some embodiments, the battery module includes a first type of cell and a second type of cell that are cells of different chemical systems, where the first type of cell includes n first cells, the second type of cell includes m second cells, n and m each are selected from an integer greater than 1, at least one of the first cells and at least one of the second cells are electrically connected in series, and the first cell and the second cell satisfy at least the following relationships: 0.08≤ΔRB/ΔRA≤3.50, and 0.10 mΩ/100 cycles≤ΔRA≤0.40 mΩ/100 cycles, where ΔRA is a discharge resistance growth rate of the first cell, and ΔRB is a discharge resistance growth rate of the second cell; and IMPBA, where IMPA is an alternating current impedance of the first cell, and IMPB is an alternating current impedance of the second cell.
