Abstract
A pressure-sensitive adhesive tape for a battery outer packaging including: a base material; and a pressure-sensitive adhesive layer arranged on one surface of the base material, where a value calculated from an expression 'a loss modulus of elasticity (G″) of the pressure-sensitive adhesive tape for a battery outer packaging at 70° C.×a thickness (mm) of the pressure-sensitive adhesive layer/a thickness (mm) of the pressure-sensitive adhesive tape for a battery outer packaging' is 8×10Pa or more; a value calculated from an expression 'a storage modulus of elasticity (G') of the pressure-sensitive adhesive tape for a battery outer packaging at 23° C. ×the thickness (mm) of the pressure-sensitive adhesive layer/the thickness (mm) of the pressure-sensitive adhesive tape for a battery outer packaging' is 3×10Pa or less; and a pressure-sensitive adhesive strength of the pressure-sensitive adhesive tape for a battery outer packaging to a stainless-steel plate at 23° C. is 2 N/10 mm or more.
