A new type of flow batteries that would be promising
Scientists at the University of Southern California (UCS) have developed a new type of redox battery from cheap and abundant materials. They used
iron sulphate, which is a waste product from the mining industry, and AQDS (or anthraquinone disulphonic acid), which is used in redox batteries because of its high stability, solubility and energy storage capacity.
They found that these two abundant and inexpensive materials can work in tandem with great effect. They have a major capacity to store energy on a large scale. In addition, the new redox flow batteries do not degrade even after hundreds of charging cycles.
Using these two components, they estimate that the cost of electricity will be $66 per kWh, less than half the cost of vanadium batteries and almost three times less than lithium-ion batteries ($156/kWh).

NDLR We are given the composition, the price, but not the defects of the process (stability, speed and size of the load, ...). As if to confirm, there is no indication of the time required for production and marketing.
