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.

摘要： The present disclosure provides a lithium-ion battery with the configuration where optical signals are output from the light-emitting parts of each unit cell that constitutes the assembled battery, wherein the complexity of wiring can be reduced, and the allowable amount of misalignment can be increased. In a lithium-ion battery (1) in which an assembled battery (50) configured by a plurality of laminated unit cells (30) is accommodated in an outer package (70), each of the unit cell is provided with a light-emitting part (20) that emits light based on the characteristics of the unit cell concerned to output an optical signal, and an optical waveguide (light guide plate) (60) is arranged adjacent or close to a light-emitting surface of the light-emitting part to be a common transmission path of the optical signal from the light-emitting part of the plurality of unit cells.
