Abstract

An adsorption assembly and a battery are provided. The adsorption assembly includes: a housing including a gas permeable portion; and an adsorbent encapsulated by the housing. The adsorption assembly can effectively isolate the adsorbent from the external environment by providing the housing, thereby preventing the adsorption performance of the adsorbent from being affected, and the housing includes a gas permeable portion, which can make the produced gas in the external environment enter the housing and be effectively adsorbed by the adsorbent. In particular, when the adsorbent is used for a battery, especially a soft pack battery, the gas produced inside the battery can be effectively adsorbed to prevent liquid leakage of the battery seal caused by breakage of the battery seal by gas, improving reliability and safety of the battery and extending lifetime of the battery.
