摘要: A battery cell (1) has an electrode composition, a frame member (3) placed annularly so as to surround the electrode composition, and a positive electrode current collector and a negative electrode current collector for closing openings of the frame member (3) from both sides in the thickness direction. The frame member (3) has a fragile portion (9) for communicating inside and outside of the frame member (3) when the pressure inside the frame member increases above a certain level. The battery cell (1) in question allows increase in the pressure inside the frame member (3), thereby preventing damage.

摘要: A cell system includes: a stacked-type cell module (100) having a plurality of lithium ion unit cells (1) being stacked and having through holes (3a, 3b) formed therein; a gas supply part (31); a cooling liquid supply part (32); a temperature sensor (35); and a control part (36) that controls switching between a normal control mode and a high-temperature control mode based on a signal from the temperature sensor (35). In the normal control mode, the control part (36) controls the gas supply part (31) to supply a gas to the through holes (3a, 3b), and at the same time, controls the cooling liquid supply part (32) to stop supply of a cooling liquid, and in the high-temperature control mode, the control part (36) controls the cooling liquid supply part (32) to supply the cooling liquid to the through holes (3a, 3b) to which the gas is supplied, and at the same time, controls the gas supply part (31) to stop supply of the gas. According to this cell system, the increase in temperature of the cell is suppressed while having a simple configuration with a reduced formation region of through holes provided in a lithium ion cell.
