Provided is a gas adsorption sheet for a secondary battery, which contains gas adsorbent particles excellent in gas adsorption property, and allows the gas adsorption performance of the gas adsorbent particles to be sufficiently exhibited. According to one embodiment of the present invention, there is provided a gas adsorption sheet for a secondary battery, including: a heat-resistant base material; and a gas adsorption layer arranged on at least one surface of the heat-resistant base material, wherein the gas adsorption layer contains: a binder resin; and gas adsorbent particles each of which is formed of an inorganic porous material having pores, and is capable of adsorbing a gas.

Gas adsorption sheet for secondary batteries

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&#x2033;) of the pressure-sensitive adhesive tape for a battery outer packaging at 70&#xb0; C.&#xd7;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&#xd7;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&#xb0; C. &#xd7;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&#xd7;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&#xb0; C. is 2 N/10 mm or more.

Pressure-sensitive adhesive tape for battery outer packaging

The present invention relates to a pressure-sensitive adhesive tape for battery containing: a substrate; and a pressure-sensitive adhesive layer provided on at least one side of the substrate, in which the pressure-sensitive adhesive tape has a thickness change ratio of 20% or less after immersion in a mixed solvent of ethylene carbonate/diethyl carbonate [former/latter (volume ratio)=1/1] at 60&#xb0; C. for 8 hours; and a 180&#xb0; peeling adhesive strength (against aluminum foil, peel temperature: 25&#xb0; C., peel rate: 300 mm/minute) of 0.5 N/10 mm or more after the above immersion.

Pressure-sensitive adhesive tape for battery and battery using the pressure-sensitive adhesive tape

An adhesive of the invention is used for polarizing plate to provide a transparent protective film on at least one side of a polarizer and comprises a resin solution comprising a polyvinyl alcohol-based resin, a crosslinking agent and a colloidal metal compound with an average particle size of 1 nm to 100 nm, wherein 200 parts by weight or less of the colloidal metal compound is added to 100 parts by weight of the polyvinyl alcohol-based resin. The adhesive for polarizing plate can reduce the occurrence of knicks.
