In 2020, China plans to launch the largest battery complex in the world with a capacity of 800 MW*h (approximately this amount of energy per year is consumed by a household with 200 apartments). This complex is based not on the usual lithium-ion or lead-acid batteries, but on the redox flow battery where the electricity is stored in the form of chemical energy of solutions—electrolytes. Battery consists of two tanks in which electrolytes are stored and membrane-electrode assembly (MEA)—solutions are supplied to MEA by pumps where they undergo electrochemical reactions which provide charging and discharging of the battery.
