Explain the working principle of vanadium battery

Vanadium battery (VRB) is a new type of clean power storage equipment. It has been verified by the United States, Japan, Australia and other countries. Compared with the lead-acid batteries and nickel-hydrogen batteries in the current market, it has high power, long life, and frequent support. Distinguished technical advantages such as current charging and discharging, green and pollution-free, are mainly used in the fields of renewable power grid-connected power generation, urban grid energy storage, remote power supply, UPS system, and island use. Disclosure data shows that after a one-time charge, the vanadium battery has a battery life of up to 1000 kilometers, and the charging time is only 3 minutes and 5 minutes. The cost is 40% of the current 24V lithium battery. It is praised in terms of battery life, charging time and cost. The perfect battery. Compared with other energy storage systems, the advantages of the all-vanadium oxidation recovery flow battery are as follows: 1. The stack is separated from the storage tank for storing the electrolyte as the place where the reaction occurs, which fundamentally overcomes the self-discharge phenomenon of the traditional battery. 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 clicked, to increase the energy storage capacity, only need to increase the volume of the electrolyte storage tank or increase the volume or concentration of the electrolyte That is, there is no need to change the size of the stack; the purpose of instantaneous charging can be achieved by replacing or adding the electrolyte in the charging state. It can be used to build energy storage power stations ranging from kilowatts to 100 megawatts, with strong adaptability. 2. Good charging and discharging performance, capable of high-power charging and discharging, as well as floating charge and deep discharge. For lead-acid batteries, the greater the discharge current, the shorter the battery life; the deeper the discharge depth, the shorter the battery life. Even if the discharge depth of the vanadium battery reaches 100%, it will not affect the battery. Moreover, vanadium batteries are not prone to short circuits, which guards against safety issues such as blasting caused by short circuits. Schematic diagram of the basic operating principle of vanadium batteries 3. The number of rechargeable and dischargeable batteries is extremely large. In theory, the life span is countless. The charging and discharging time ratio is 1:1, while the lead-acid battery is 4:1. In addition, the charging and discharging switching speed of vanadium batteries is fast, less than 20 milliseconds, which is very conducive to balanced power supply. 4. High energy power. DC to DC energy power can reach more than 80%, while lead-acid battery only has about 60%. The condition of each unit battery in the vanadium battery pack is basically the same, and the protection is simple and convenient. 5. The site selection is free and occupies a small area. The system can be automatically shut down and operated without acid mist or acid corrosion. The electrolyte can be reused, no emissions, simple protection, and low operating cost. It is a green energy storage technology. Therefore, regarding renewable power generation, vanadium batteries are an ideal substitute for lead-acid batteries.
