SYSTEM ENERGY DENSITY IN A REDOX FLOW BATTERY

摘要

A redox flow battery (RFB) controllable by a battery management system and having an energy output has a volume of at least 2000 liters and an energy density of at least 10 w-h/liter. In one embodiment, the RFB maintains at an energy density of at least 10 w-h/liter for a minimum of 50 continuous full charge/discharge cycles or the equivalent number of operating hours without user input.

主权项

1. A redox flow battery (RFB) controllable by a battery management system and having an energy output, comprising:
at least one anolyte tank and at least one catholyte tank; at least one stack comprising electrochemical cells; at least one anolyte circulating system; at least one catholyte circulating system; at least one crossover pipe that fluidically connects the at least one catholyte tank and the at least one anolyte tank for electrolyte exchange; and one or more contiguous containers configured to house the at least one anolyte tank, the at least one catholyte tank, the at least one stack, the at least one anolyte circulating system, and the at least one catholyte circulating system in a substantially enclosed manner, wherein the one or more containers has a volume of at least 2000 liters and wherein the RFB operated by the battery management system has an energy density of at least 10 w-h/liter.
