Abstract: A method for key predictors and machine learning for configuring battery cell performance may include providing a cell comprising a cathode, a separator, and a silicon-dominant anode; measuring a plurality of parameters of the cell; and using a machine learning model to determine cell performance based on the plurality of measured parameters. The plurality of parameters may include initial coulombic efficiency and/or second cycle coulombic efficiency. Cells may be classified based on the determined cell performance and similarly performing cells may be binned together. A battery pack may be provided with a plurality of cells. The plurality of cells may be assessed during cycling using the machine learning model. One or more of the plurality of cells may be replaced from the battery pack when the assessing determines a different performance of the one or more of the plurality of cells. The battery pack may be in an electric vehicle.

Abstract: Systems and methods provide for safety of silicon dominant anodes in a battery. The battery may include an anode comprising an anode active material layer on a metal current collector, where the anode active material layer comprises pyrolyzed binder, conductive additives, and 50% or more silicon by weight. The battery may further include a separator, an electrolyte, a cathode, and a solid electrolyte interface between the anode active material layer and the electrolyte, and has a thermal runaway temperature of greater than 260 C. The conductive additives may comprise between 1% and 40% of the active material layer. The anode active material layer may comprise between 20% to 95% silicon. The separator may comprise ceramic-coated polyolefin or polymer-coated polyolefin. The electrolyte may comprise Lithium hexafluorophosphate (LiPF6) and/or lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) in one or more electrolyte solvents. The metal current collector may comprise copper.
