<P>PROBLEM TO BE SOLVED: To provide an electrochemical device capable of efficiently preventing an internal pressure rise in a package in which a storage element is included. <P>SOLUTION: The electrochemical device comprises a storage element 10, a pair of terminals 20 electrically connected to the storage element 10, a gas absorber 30, a liquid holding member 40 interposed between the gas absorber 30 and the storage element 10, and a package 50 comprising a laminate film including the storage element 10, electrolyte (not shown), the gas absorber 30 and the liquid holding member 40. In the electrochemical device, the gas absorber 30 is filled in the package 50, and lithium which is easy to react with carbon dioxide is doped in an active material layer 32 of the gas absorber 30. Therefore, carbon dioxide generated by dissolving propylene carbonate is absorbed by the reaction with lithium doped in the active material layer 32. <P>COPYRIGHT: (C)2012,JPO&INPIT |
