Description

Background technique [0001] Removable power storage has been dominated by lithium-based battery technology. Demand for this power is increasing with the electrification of vehicles, such as electric vehicles, and the growing popularity of portable consumer electronics. Typically, lithium-ion batteries are capable of delivering power in the microwatt to kilowatt range, while megawatt-capacity batteries have only recently been developed. High-capacity lithium-based batteries may use materials that are expensive to produce and place. [0002] The ability to store megawatt-hours of energy is necessary for grid and renewable energy applications. Currently, large-scale flow batteries are being developed for such applications due to their stability and scalability compared to lithium-based batteries. Flow batteries use a pair of chemical components that circulate through the cell, harnessing chemical energy to generate electricity. However, flow batteries are usually stationary b...
