<P>PROBLEM TO BE SOLVED: To obtain a lithium ion cell having a structure which controls the temperature in the cell and equalizes the temperature distribution of the entire cell. <P>SOLUTION: Each lithium ion cell 1 is disposed in the middle of a cooling passage 9 where a cooling medium C flows. A connection part 4a, having a large heat value, is disposed at the upstream side of the cooling passage 9 from among the pair of connection parts 4a, 4b connecting with a charge/discharge part 2 in a cell container 5. The connection part 4b, having a small heat value, is disposed at the downstream side of the cooling passage 9. This structure suppresses the temperature rise of the cell at the downstream side and equalizes the temperature distribution of the entire cell. <P>COPYRIGHT: (C)2013,JPO&INPIT |
