Gas adsorption sheet for secondary battery with cover film

Abstract

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. A gas adsorption sheet for a secondary battery with a cover film according to an embodiment of the present invention includes: a gas adsorption sheet for a secondary battery including a heat-resistant base material, and a gas adsorption layer arranged on at least one side of the heat-resistant base material; and a cover film arranged on the gas adsorption layer on a side opposite to the heat-resistant base material. 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.
