1. A battery module for a vehicle, the battery module comprising:
a first battery cell, wherein:
the first battery cell has a planar shape,
the first battery cell extends in one direction, and
the first battery cell comprises a first positive electrode and a first negative electrode;
a second battery cell, wherein:
the second battery cell has the planar shape,
the second battery cell extends in the one direction, and
the second battery cell comprises a second positive electrode and a second negative electrode; and
a main cartridge,
wherein:
the main cartridge comprises an insertion space in which the first battery cell and the second battery cell are slidably inserted,
the first positive electrode and the second negative electrode are arranged alternately in a stacking direction and protrude outwards,
the first negative electrode and the second positive electrode are arranged alternately in the stacking direction and protrude outwards,
a stepped portion is provided in an inward end portion of the insertion space,
a first inner surface of the stepped portion is in contact with a first inward end portion of the first battery cell,
a second inner surface of the stepped portion is in contact with a second inward end of the second battery cell,
the first inner surface of the stepped portion and the second inner surface of the stepped portion are spaced apart from each other in a sliding direction of the first battery cell and the second battery cell,
a first positive electrode end portion of the first positive electrode and a second negative electrode end portion of the second negative electrode are in contact with and overlap each other when the first positive electrode and the second negative electrode are bent in the stacking direction to be connected to each other, and
a first negative electrode end portion of the first negative electrode and a second positive electrode end portion of the second positive electrode are in contact with and overlap each other when the first negative electrode and the second positive electrode are bent in the stacking direction to be connected to each other.
