Abstract
The battery has an electrode assembly that includes one or more anodes and one or more cathodes. A first liquid phase is positioned in an active region of the electrode assembly. The first liquid phase includes one or more first flame retardants and an electrolyte. A second liquid phase is outside of the active region and in contact with the first liquid phase. The second liquid phase includes one or more second flame retardants. A third liquid phase is outside of the active region and in contact with the second liquid phase. The third liquid phase includes one or more third flame retardants. The first liquid phase and/or the electrolyte have a density between the second liquid phase and the third liquid phase.
