澳门渔人码头棋牌Core IPEX has confirmed its novel hydrometallurgical process at X GROUP research and development facilities in South Africa for producing high purity vanadyl sulphate for conversion to Vanadium Redox Flow Battery (VRFB) electrolyte.
澳门渔人码头棋牌Vanadium Flow batteries are attracting a lot of attention because of their ability of mass power storage, combined with their inherent simplicity of construction, use and safety. Core IPEX’s work is aimed at much improved processes to produce VRFB electrolyte to be used in these batteries.
澳门渔人码头棋牌Core IPEX’s work is currently producing vanadyl solutions at around 99.8% grade, with Na constituting 0.14% of total impurities. Recent investigations at bench scale showed Na levels may be further reduced to below 0.02% which will allow >99.9% purity electrolyte to be produced on a sustainable basis. Further pilot scale trials are planned from March 2020 and improved control over Na levels.
澳门渔人码头棋牌Complete demineralisation of make-up water into the ion exchange process will be incorporated into the upcoming trials to further reduce traces of chloride, calcium and iron. This further refinement promises vanadyl sulphate solution of even higher purities, closer to 99.99%.
Conversion of vanadyl sulphate to VRFB electrolyte will be carried out in the piloting facilities of Core IPEX located in the laboratories of Core Resources in Brisbane. The further processing includes vanadium and acid molar corrections as well as adjustments to V3+ and V4+ ratios by electrolysis. This novel approach promises premium quality electrolyte at a compellingly low cost compared to conventional processing alternatives.
