Method and system for safety of silicon dominant anodes |
| 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. |
