Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A gas adsorption sheet for a secondary battery, comprising: 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: an acrylic resin; and gas adsorbent particles each of which is formed of an inorganic porous material having pores, and is capable of adsorbing a gas, wherein the acrylic resin contains a constituent unit derived from a (meth)acrylic acid alkyl ester, wherein the (meth)acrylic acid alkyl ester has a linear or branched alkyl group having 4 to 12 carbon atoms, wherein a content of a constituent unit derived from a (meth)acrylic acid alkyl ester having a branched alkyl group in the acrylic resin is from 20 parts by weight to 100 parts by weight with respect to 100 parts by weight of the constituent unit derived from the (meth)acrylic acid alkyl ester, and wherein a material for forming the heat-resistant base material is polyamide imide, polyetherimide, polyphenylene sulfide, polyethylene naphthalate, polyimide, or polyetheretherketone. 2. The gas adsorption sheet for a secondary battery according to claim 1 , wherein a content of the gas adsorbent particles is from 10 parts by weight to 90 parts by weight with respect to 100 parts by weight of the gas adsorption sheet for a secondary battery.
