NOVELTY - The flow battery (200) has at least one cell with low resistance positive electrode (212) in positive half cell and low resistance negative electrode (222) in negative half cell. A pump (263) circulates electrolyte through a flow channel (221) of negative half cell. The pump and flow channel provide high mixing rate of electrolyte in the deposition region proximate the deposition surface. The electrolyte has a greater metal ion concentration than the equilibrium saturation concentration of metal ion in the electrolyte.    USE - Flow battery e.g. alkaline zinc/ferro-ferricyanide rechargeable flow battery or zinc redox flow battery for hybrid vehicle and all electric vehicles.    ADVANTAGE - Enables low cost manufacture of high capacity, efficient and high performance flow battery with battery design having cell stack consisting of low resistance positive electrode and low resistance negative electrode in which electrode resistances are selected for uniform high current density across the region of the cell stack. Allows flow of electrolyte having high mixing level through at least one negative half cell in the zinc deposition region proximate the deposition surface, where the electrolyte close to the deposition surface has sufficiently high zinc concentration for deposition rates on the deposition surface that sustain the uniform high current density. Enables to optimize a high performance redox flow battery including engineering the flow rate and flow channel of the flow battery to ensure uniform mass transfer rate across the deposition surface at optimal fluid velocity, local current density to amount that is sufficiently high to prevent mossy deposition and the concentration depletion along the flow channel on the zinc side to approximately not greater than 10 percent of the inlet concentration. Reduces pump power consumption by ensuring a laminar or substantially laminar flow outside of any intentional turbulent region of the cell.
