Material cost and energy storage capacity are factors that are developing each type of energy storage system must consider. Some materials such as lead, zinc or nickel, low price, rich global reserves, but their electrochemical performance is not as good as lithium or vanadium. In addition, these two metal reserves are rare and difficult to obtain.
Vanadium imported in Russia, my country and South Africa, important for manufacturing alloy steel. Vanadium is also used in liquid flow battery electrolytes, but it is very expensive in the global metal market, only steel companies can bear. Vanadium can also be obtained by recovering purity by slag, oilfield sludge and volcanic ash, but it is difficult to reach 99.
5% purity, and vanadium flow battery electrolyte requires vanadium purity to 99.5%. At the beginning of this month, IMERGY, headquartered in California, announced a new process, using the process extracted by 58.
5%. IMergy uses this process to extract vanadium for company vanadium flow battery electrolyte. Although the purity of 99.
5% is only 1%, it can be greatly reduced, and self-sufficient is achieved by purification. IMergy's predecessor is Deeyaenergy, focusing on iron-chrome flow battery, renamed IMergy in 2013, and began to transfer business to new technologies developed by Chief Technology MAJIDKESHAVARZ. At present, IMERGY is working with other remote equipment for cellular tower, which has produced 5KW / 30KWH batteries, and 30KW / 120KWH large vanadium flow battery system is being designed and tested.
It is important to supply spare power for microgrid and building. IMergy is not the only company that tries to find a cost of cutting raw materials, and many companies such as aluminum industry are constantly looking for new ways to cut costs.
