As the place where the reaction occurs, the vanadium stack is separated from the storage tank for storing the electrolyte, which fundamentally overcomes the self-discharge phenomenon of traditional batteries. The power only depends on the size of the stack, and the capacity only depends on the electrolyte storage and concentration. The design is very flexible; when the power is constant, to increase the energy storage capacity, it is only necessary to increase the volume of the electrolyte storage tank or increase the volume or concentration of the electrolyte. Yes, without changing the size of the stack; the purpose of “instant charging” can be achieved by replacing or adding the electrolyte in the state of charge. It can be used to build kilowatt-level to 100-megawatt energy storage power stations, with strong adaptability.
VRFB has a large degree of freedom in site selection and occupies less land. The system can be fully closed and operated without acid mist and acid corrosion. The electrolyte can be reused, no emissions, simple maintenance and low operating costs. It is a green energy storage technology. Therefore, for renewable energy generation, vanadium batteries are ideal substitutes for lead-acid batteries.
Vanadium battery features long system life. System efficiency is high. The cycle efficiency of the vanadium battery system can reach 65-80%. Support frequent charging and discharging. Vanadium batteries support frequent high-current charging and discharging, and can be charged and discharged hundreds of times a day without reducing battery capacity. It supports overcharge and overdischarge. The vanadium battery system supports deep charge and discharge (DOD 80%) without damaging the battery. The charge-discharge ratio is 1.5:1. The vanadium battery system can realize fast charge and discharge to meet the load requirements. Low self-discharge rate. The active materials in the positive and negative electrolytes of vanadium batteries are stored in separate tanks. In the system shutdown mode, the electrolyte in the tank has no self-discharge phenomenon.
Startup is fast. During the operation of the vanadium battery system, the charging and discharging time is less than 1 millisecond/the battery system design is flexible. The power and capacity of the vanadium battery system can be independently designed and configured according to customer requirements to achieve rapid upgrades. Low maintenance cost. The vanadium battery system realizes fully automatic operation, low operating cost, long maintenance period and simple maintenance. Environmentally friendly and pollution-free. The vanadium battery system is closed at room temperature and meets environmental protection requirements. It can be fully recovered without any disposal issues.
