    Abstract: According to one or more embodiments, a method of producing a lithium-ion cell includes constructing a cell defining a cavity housing an electrode assembly including a cathode, an anode, a separator, and an electrolyte, forming the cell to generate formation gas in the cavity, and releasing the formation gas from the cavity. The method further includes placing a solid adsorbent in the cavity adjacent the electrode assembly after the releasing, and sealing the cavity with the solid adsorbent therein such that post-formation gas is adsorbed by the solid adsorbent in the cavity.

    Abstract: A metal-ion battery includes an anode assembly and a cathode assembly ionically coupled by an electrolyte. The anode assembly includes a current collector and an anode material capable of intercalation of metal-ions. When the battery is at rest, ionic transfer between the anode and cathode at a minimum and the anode assembly potential with respect to the electrolyte may increase. The increased potential may exceed the reduction potential of the current collector material causing ions to erode from the current collector and contaminate the cathode. The use of a metal, metal alloy or metal compound reduces the rest potential and erosion of the current collector. For example, a lithium foil physically in contact with a copper current collector in a lithium-ion battery reduces the overall anode potential thereby reducing copper dissolution.
