Blister pack packaging material for lithium battery

Abstract

Abstract PURPOSE:To prevent the secular quality deterioration of a battery by using a multilayer lamination film with the property of vapor barriers that are not provided with a voltage measurement window hole as the blister pack packaging material. CONSTITUTION:A lithium coin type battery 1 is set in a multilayer lamination film 12 and a circumference 20 is heat-sealed by covering a multilayer lamination film 13 from above. The multilayer lamination film is set so that the polyethylene film can form the inside and the polyester film can form the outside. As a result, since the lithium battery is covered by the vapor barrier film, the secular quality deterioration of the battery caused by moisture can be prevented.
