BATTERY MODULE

摘要

PURPOSE: A battery module is provided to reduce constant resistance because a plurality of electrode groups are electrically connected through a conductive barrier and to decrease the weight of a battery module. CONSTITUTION: A battery module(100) includes: a plurality of electrode groups including a positive electrode, negative electrode and a separator arranged between the positive electrode and the negative electrode; a housing in which the electrode group is built in; and a conductive barrier which partitions the inner space of the housing and electrically connects the electrode groups.
