Metal-based batteries incorporating magnets to apply Lorentz force are disclosed herein. In one example, a zinc-bromine battery includes an aqueous electrolyte containing bromine (Br.sub.2), bromine ion complexes, or bromine precursors, a plurality of zinc cations (Zn.sub.2+), and a plurality of anions of bromine; a first electrode containing zinc (Zn); a second electrode in fluid communication with the first electrode via the aqueous electrolyte; and a magnet proximate to the first electrode and/or the second electrode. The magnet has a field strength to exert sufficient Lorentz force on the plurality of zinc cations (Zn.sub.2+) such that the zinc cations (Zn.sub.2+) forming a vortex proximate to a surface of the first electrode during galvanic charging and discharging of the zinc-bromine battery.

A core pack assembly, a battery, a battery pack, and a vehicle are provided. The core pack assembly includes a core pack and one or more wicking components. The core pack is provided with tabs, and each wicking component is arranged on an outer surface of the core pack and located on a same side of the core pack as the tabs, and is configured to absorb electrolyte outside the core pack and transfer the electrolyte into the core pack.
