BATTERY UNIT

摘要

Disclosed is a battery unit (1) comprising a plurality of bipolar cells (2) and collectors (3) arranged between the bipolar cells (2). Each of the bipolar cells (2) is obtained by stacking a plurality of cell elements in each of which a sheet electrode is arranged on both sides of an electrolyte. The collectors (3) serve as heat dissipating members for dissipating the heat generated in the bipolar cells (2). In addition, each of the collectors (3) is provided with a heat dissipating structure which is capable of dissipating the heat generated in the bipolar cells (2).
