<P>PROBLEM TO BE SOLVED: To solve the problem in which: a laminated battery is different from conventional lithium ion batteries; its sheath material is composed of films; and therefore, battery blistering arises due to insufficient strength for suppressing deformation of the sheath material when gas is generated inside the laminated battery. <P>SOLUTION: In the laminated battery, a gas adsorption layer 1 is formed on an interior surface portion except sealed portions in an interior surface of a housing part 16 of an electrode group 1 of a sheath material 14 composed of laminate films. The gas adsorption layer 1 is configured to absorb gas generated inside. <P>COPYRIGHT: (C)2012,JPO&INPIT |
