摘要： PROBLEM TO BE SOLVED: To prevent the breakage of a cell and enhance the cell life by lowering the temperature of the cell in the state where the temperature of the cell upper part is regularly lower than the lower part, when the cell temperature is lowered, so as to solidifying positive and negative electrode active materials from the cell upper part toward the lower part. SOLUTION: In a module vessel 11, cells 10 are housed within cell covers 12, and the adjacent covers 12 are mutually connected by a cell cover connecting plate 18. The vessel 11 has a fluid temperature control device 16 for the heating and cooling necessary for temperature rise and fall of the cells, and an inlet pipe 14 for introducing a heating and cooling fluid 8 into the vessel 11 and an exhaust pipe 15 for exhausting it are set on the upper part of the vessel 11. A periodic inspection requires to lower the temperature from steady operating temperature to room temperature. Since the cooling fluid 8 is then carried on the upper part of the vessel 11, the cell 10 is gradually cooled from the upper part to the lower part. Since the positive and negative active materials are thus solidified from the cell upper part to the lower part within the battery 10, the density is roughed to produce holes, so that no stress acts on each cell component to transformation expansion, particularly, after solidification of sulfur of the positive electrode active material.
