CELL MODULE AND POWER SUPPLY

摘要

PROBLEM TO BE SOLVED: To provide a cell module having a compact size by virtue of an effective cooling of a unit cell, as well as having a long life by virtue of a reduction in temperature dispersion. SOLUTION: A cell module 1 and a power supply 300 have a battery 18 formed of plural layers of a stack of a positive electrode foil 101a, a negative electrode foil 101b and an insulating separator 102. The battery 18 is included within a cell container 19. Plural layers of the positive electrode foil 101a and the negative electrode foil 101b are extended from the separator 102, and connected electrically and thermally to positive and negative electrode portions 103 and 104 in the cell case 19. A heat sink 20 is thermally connected to the positive and negative electrodes 103 and 104.
