US Patent 11349161 Rechargeable battery with hydrogen scavenger

Energy storage devices, battery cells, and batteries of the present technology may include a first current collector and a second current collector. The batteries may include an anode material coupled with the first current collector. The batteries may include a cathode material coupled with the second current collector. The batteries may also include a separator positioned between the cathode material and the anode material. The batteries may include a hydrogen-scavenger material incorporated within the anode active material or the cathode active material. The hydrogen scavenger material may absorb or react with hydrogen at a temperature above or about 20° C.
