GAS ADSORBER IN LITHIUM-ION BATTERIES

Aspects of the disclosure include lithium-ion cells with gas adsorbers and methods of manufacturing the same. An exemplary vehicle includes an electric motor and a battery pack electrically coupled to the electric motor. The battery pack includes a battery cell that includes an anode layer having an anode active material and an anode current collector, a cathode layer having a cathode active material and a cathode current collector, and a separator positioned between the anode layer and the cathode layer. The battery cell further includes a gas adsorber having a gas adsorbent material. The gas adsorbent material is selected to react with at least one offgas that includes a gas phase cycling byproduct produced when cycling the battery cell to form a compound having a solid phase under a cycling temperature and a cycling pressure of the battery cell.
