    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 vehicle includes a traction battery and a controller in communication with the battery and programmed to control battery charging in response to a user-selected one of a plurality of charging strategies having different charging rates based on detection of lithium plating in the battery. The charging strategies may include options for faster charging with an urgent or emergency charging strategy selectable a limited number of times to mitigate battery performance degradation associated with lithium plating. A method implemented by a vehicle controller in a vehicle having a traction battery, may include controlling, by the controller, battery charging in response to a user-selected charging strategy selected from one of a plurality of available charging strategies each having a different charging rate and displayed on a user interface in response to detection of lithium plating in the traction battery, at least one charging strategy associated with additional lithium plating if selected.

    Abstract: A lithium-ion battery component and pre-cured electrode are disclosed, featuring a current collector and a slurry containing graphite, silicon-based particles, and a chemically cross-linkable monomer. Upon initiation, the monomer chemically crosslinks to form a binder that mechanically binds the graphite and silicon-based particles, creating a coating adhered to the current collector the chemically crosslinked binder enables volume expansion during charging and facilitates volume contraction during discharging, maintaining some of the electrode's initial capacity. The chemically cross-linkable monomer is present at a weight percentage relative to the graphite and silicon-based particles, while the current collector is composed of a metal foil. The battery component and pre-cured electrode may increase performance and longevity in lithium-ion batteries through their chemically crosslinked binder and slurry composition.
