A new 70 kW-level vanadium flow battery stack, developed by researchers, doubles energy storage capacity without increasing costs, marking a significant leap in battery technology.
Recently, a research team led by Prof. Xianfeng Li from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) developed a 70 kW-level high power density vanadium flow battery stack. Compared with the current 30kW-level stack, this stack has a volume power density of 130kW/m3, and the cost is reduced by 40%.
Vanadium flow batteries are one of the preferred technologies for large-scale energy storage. At present, the initial investment of vanadium flow batteries is relatively high.
Ferro-Alloy Resources Ltd (LON:FAR) is developing the giant Balasausqandiq vanadium deposit in Kyzylordinskaya oblast of southern Kazakhstan. The ore at this deposit is unlike that of nearly all other primary vanadium deposits and is capable of being treated by a much lower cost process.
