RE: News Technical Difficulties And Latest Development Of Vanadium Battery3 Aug 2020 21:56
good find ...
"However, the installed capacity of vanadium battery is gradually increasing. According to the statistics of international vanadium Technical Committee, there are 113 vanadium battery projects in operation in the world, with a total installed capacity of 39.664mw and a total capacity of 209.8mwh"
The theory and application of lithium battery are very mature, and the energy density is very high, which is an advantage. But vanadium batteries are used for scale power. β Yan Chuanwei said that this involves different industrial links. Vanadium batteries are suitable for large capacity energy storage applications, while lithium batteries involve small capacity.
Based on different application scenarios, the technical advantages of the two batteries are also different. The charge and discharge of vanadium battery does not involve solid state reaction, and the loss of electrolyte is very small. Based on this advantage, vanadium battery used in large-scale power storage will reduce the power loss in the transmission phase
"The main thing is that the cost is too high.β Zhang Zhongyu said that the theme of his report at the forum was to reduce the cost of vanadium battery. βTaking 10kW / 40kwh vanadium battery energy storage system as an example, the cost of energy storage system accounted for the largest proportion of vanadium electrolyte cost, accounting for 41% of the total cost, and the cost of power stack reached 37%, and the total cost of both reached 78%. The most effective way to reduce the price of vanadium battery is to reduce the production cost of vanadium electrolyte and stack"
