Abstract
The application relates to a battery module, a manufacturing method and a manufacturing device thereof, a battery pack and a power consumption apparatus. The battery module includes a first-type battery cell and a second-type battery cell having different chemical systems and being electrically connected at least in series, where under the conditions of 25° C. and 100% state of charge (SOC), specific power density Pof the second-type battery cell is higher than specific power density Pof the first-type battery cell. Satisfying: 0.04≤(r/m)/(r/n)≤14, where, rand rare resistances per unit area of a positive electrode plate of the first-type battery cell and a positive electrode plate of the second-type battery cell respectively, and m and n are numbers of laminations of the positive electrode plate of the first-type battery cell and the positive electrode plate of the second-type battery cell.
