Abstract

A lithium-ion battery outer package material includes a base layer, a first adhesive layer, a metallic foil layer, a corrosion prevention treatment layer, a second adhesive layer, and a sealant layer sequentially layered on one of the surfaces of the base layer. When a tensile test is performed in a 23° C. and 40% RH environment, with the specimen width being 15 mm, the distance between gauge points being 50 mm, and the tensile speed being 100 mm/min, the tensile elongation and tensile stress of the specimen are measured. A ratio of tensile elongation measured in a first direction to tensile elongation measured in a second direction is from 135:85 to 140:75, and a ratio of tensile stress measured in the first direction to tensile stress measured in the second direction is from 195:225 to 200:229.
