Abstract: The present disclosure relates to a battery module comprising a first battery unit and a second battery unit, each of which comprises N secondary batteries, N is an integer greater than or equal to 2, and each secondary battery comprises a first electrode lead and a second electrode lead having opposite polarities. The first electrode lead has a melting point higher than that of the second electrode lead, and N first electrode leads of the first battery unit and N second electrode leads of the second battery unit are arranged to form a layered construction. The battery module has a plurality of connection points distributed in the layered construction, the number of which is greater than or equal to N, and each connection point is adapted to electrically connect one first electrode lead of the first battery unit to at least one second electrode lead of the second battery unit.
