What are the advantages of vanadium batteries compared with traditional lithium batteries?

What are the killer features of vanadium batteries compared with traditional lithium batteries? Vanadium battery is a new type of clean energy storage device. It has been verified by applications in the United States, Japan, Australia and other countries. Compared with lead-acid batteries and nickel-hydrogen batteries in the current market, it has high power, long life, and supports frequent high-current charging. Discharge, green and pollution-free and other obvious technical advantages are mainly used in renewable energy grid-connected power generation, urban grid energy storage, remote power supply, UPS systems, island applications and other fields. ①High efficiency: due to the high catalytic activity of the electrode of the vanadium storage battery, and the positive and negative electrode active materials are stored in the positive and negative electrode electrolyte storage tanks respectively, the self-discharge consumption of the positive and negative electrode active materials is prevented, and the charge and discharge energy conversion of the vanadium storage battery The efficiency is as high as 75% or more, which is much higher than 45% of lead-acid batteries. ②Long life: Since the positive and negative active materials of the vanadium battery only exist in the positive and negative electrolytes, there is no phase change common to other batteries during charging and discharging, and the battery can be deeply discharged without damaging the battery, and the battery has a long service life. ③The capacity and power of vanadium batteries are relatively independent. Generally speaking, the capacity and power of traditional lithium batteries are related to each other. If you want to increase one of them, the other must be increased; flow batteries can be filled with new liquid and electrolyte Increase the capacity by increasing the volume, and increase the system power by increasing the size of the stack. ④Good charging and discharging performance, high-power charging and discharging can be carried out, floating charging and deep discharge are also allowed. Even if the discharge depth of the vanadium battery reaches 100%, it will not affect the battery; and the vanadium battery is not prone to short-circuit, which prevents safety problems such as explosion caused by short-circuit. So far, there have been many demonstration projects of vanadium storage batteries at home and abroad; in general, vanadium storage batteries are still in the demonstration stage. To enter the stage of industrialization and commercialization on a large scale, more breakthroughs must be made in electrolyte, electrode materials, ion exchange membranes, battery module assembly technology, and battery system assembly technology. Many technological breakthroughs made by lithium batteries will also spill over to vanadium batteries, thus accelerating the industrialization process of vanadium batteries.
