Could a rechargeable flow battery save energy?

MIT researchers have engineered a new rechargeable flow battery that doesn’t rely on expensive membranes to generate and store electricity. The device, they say, may one day enable cheaper, large-scale energy storage.

How do flow batteries increase power and capacity?

Since capacity is independent of the power-generating component, as in an internal combustion engine and gas tank, it can be increased by simple enlargement of the electrolyte storage tanks. Flow batteries allow for independent scaleup of power and capacity specifications since the chemical species are stored outside the cell.

What is a redox flow battery?

Redox flow batteries (RFBs) constitute an attractive renew-able energy storage technology which, unlike Li ion batteries, can be scaled up with independent control of the system’s energy and power capacities.

What is a flow battery?

Flow batteries allow for independent scaleup of power and capacity specifications since the chemical species are stored outside the cell. The power each cell generates depends on the current density and voltage. Flow batteries have typically been operated at about 50 mA/cm 2, approximately the same as batteries without convection.

How much power does a flow battery produce?

In experiments, Braff and his colleagues operated the flow battery at room temperature over a range of flow rates and reactant concentrations. They found that the battery produced a maximum power density of 0.795 watts of stored energy per square centimeter.

Why is a flow battery more efficient?

Also, note that as the volume of the cell components gets small relative to the volume of the electrolytes, the flow battery approaches its theoretical maximum of energy density. Higher capacity systems are thus more efficient in this respect, as the majority of the weight is the electrolyte which directly stores energy.
