Abstract: The disclosure relates to an output electrode plate and a battery module. The output electrode plate comprises a first metal plate. The first metal plate includes a first region and a second region in a first direction. The first region includes a first overcurrent portion and a second overcurrent portion in a second direction. The second region is connected to the first region. The first overcurrent portion is provided with a through hole which extends in a thickness direction thereof, and a projection of the through hole along the first direction does not exceed a projection of the second region along the first direction in the second direction, and the first metal plate is formed with a minimum overcurrent section at the through hole, such that the minimum overcurrent section is first fused when a current flowing through the first metal plate is greater than a preset current.
