NOVELTY - Resin composition comprises propylene-type modified resin and propylene-based resin. The propylene-type modified resin is obtained by modifying propylene-based resin (a) using ethylenically unsaturated compound (b), and has melting peak temperature of 115-135 degrees C, storage elastic modulus (G'80) of 100 MPa or more at 80 degrees C based on temperature-storage-elastic-modulus curve, and molecular weight distribution obtained by gel permeation chromatography measurement of 1.5-2.5 which is ratio of weight average molecular weight and number average molecular weight.    USE - Resin composition is used for laminated component for battery container for lithium-ion battery (all claimed). Uses include but are not limited to notebook computer, mobile telephone, packaging material for pharmaceutical, retort foodstuff and foodstuff, poultice, medical supplies, trim material and dampproof membrane.    ADVANTAGE - The laminated component obtained using the resin composition has excellent barrier property with respect to water vapor and electrolyte solution, chemical resistance, self-heat sealing property, and mechanical strength, high adhesive strength even at high temperature.    DETAILED DESCRIPTION - Resin composition comprises 30-65 wt.% propylene-type modified resin and 70-35 wt.% propylene-based resin. The propylene-type modified resin is obtained by modifying propylene-based resin (a) using ethylenic unsaturated compound (b), and has melting peak temperature of 115-135 degrees C based on melting curve obtained by differential scanning calorimeter, storage elastic modulus (G'80) of 100 MPa or more at 80 degrees C based on temperature-storage-elastic-modulus curve obtained by solid viscoelasticity measurement, and molecular weight distribution obtained by gel permeation chromatography measurement of 1.5-2.5 which is ratio of weight average molecular weight and number average molecular weight. INDEPENDENT CLAIMS are included for the following:    (1) laminated component, which is formed using contacting aluminum layer and adhesive resin layer. The adhesive resin layer contains resin composition;    (2) battery container, which is obtained by overlapping the laminated component such that heat seal resin layers are opposingly arranged, heat-sealing edge portion, and forming into bag shape; and    (3) lithium-ion battery, which has battery container.
