With the continuous escalation of the energy crisis, new energy is being vigorously developed around the world. However, due to the instability of new energy sources such as wind energy and solar energy, it has become a top priority for all countries to seek a good energy storage system. Among new batteries such as lithium batteries and sodium-sulfur batteries, vanadium batteries are recognized as the best energy storage batteries.

Vanadium battery is a new type of battery researched and developed in recent years. Its full name is all-vanadium redox flow battery. It is reported that the main advantages of vanadium batteries are deep discharge at high current density, long cycle life, rapid charging, and low price compared to other energy storage devices. Moreover, currently my country's vanadium mines account for 35% of the global vanadium mines, and the output accounts for 48% of the world's, ranking first in the world, enabling low-cost mass production.

At present, new energy sources such as solar energy, wind energy and tidal energy have been continuously developed and utilized. Due to the unpredictable and changeable characteristics of these new energy sources, a good energy storage system is required to store these energy sources in order to achieve better more fully utilized. Compared with other batteries such as lithium batteries, vanadium batteries are very suitable for large-scale static energy storage.

Vanadium batteries have broad application prospects in energy storage. According to the relevant data of the battery industry in recent years and my country's newly released "New Energy Vehicle Industry Development Plan", it can be estimated that the current market for lead-acid batteries, lithium batteries and other automotive power batteries accounts for a large proportion, while the wind power used in vanadium batteries The market size of energy storage equipment and urban peaking energy storage equipment will be about four times that of it.

The development of vanadium batteries in Japan and other countries has entered a relatively mature stage. The high-power vanadium battery energy storage system has been put into use and has begun to enter the stage of large-scale commercialization. my country's current research on vanadium batteries is still in its infancy. In the field of large-scale vanadium energy storage batteries, it is considered that it will take time to realize industrialization. However, due to the good application prospects of vanadium batteries in large-scale energy storage, it has also attracted the attention of many battery manufacturers in recent years.
