MATERIAL CAPABLE OF ABSORBING CARBON MONOXIDE AND CARBON DIOXIDE, POWER STORAGE DEVICE ARRANGED BY USE THEREOF, AND METHOD FOR PRODUCING MATERIAL CAPABLE OF ABSORBING CARBON MONOXIDE AND CARBON DIOXIDE

摘要

PROBLEM TO BE SOLVED: To provide a material capable of absorbing CO and COwhich enables the reduction of the quantity of gas (CO, CO, and nitrogen gas) generated inside an enclosure of a power storage device; a method for producing such a material; and a power storage device having such a material filled therein.SOLUTION: A material capable of absorbing CO and COis filled in a battery case 3 of a lithium ion battery E having a positive electrode terminal 1, a negative electrode terminal 2, and a nonaqueous electrolyte enclosed in the battery case 3 (enclosure) together. The material capable of absorbing CO and COcomprises: A-type or LSX-type zeolite having undergone a degassing treatment and a moisturizing treatment for moisturizing the surface with the nonaqueous electrolyte before the filling.
