With the overall expansion of the industry, new energy storage has entered a period of rapid development, and the market's demand for long-term energy storage has increased. Emerging technological paths suitable for constructing large-scale electrochemical energy storage facilities, such as vanadium flow batteries, are also accelerating their layout. As a new force in the field of energy storage, all vanadium flow batteries are poised to emerge.

Fluid flow batteries are tailor-made for energy storage, with stable performance and high safety

Liquid flow battery is a battery technology in which active substances exist in liquid electrolytes. The electrolyte flows through the stack outside the stack under the propulsion of a circulating pump, achieving the conversion of chemical and electrical energy. There are four main technical routes for flow batteries internationally: all vanadium flow batteries, zinc bromide batteries, iron chromium batteries, and sodium polysulfide bromide batteries. Compared to other electrochemical energy storage technologies, flow batteries have inherent safety and ultra long cycle life, making them particularly suitable for large-scale energy storage power plants.

The current industrial chain construction and technological maturity of all vanadium flow batteries are relatively high. Unlike the logic of lithium-ion batteries in energy storage applications, liquid flow batteries are mainly due to their scalability, which can break through the limitations of lithium-ion batteries in energy storage time in the power system, and are used for long-term energy storage. Therefore, they have certain development space in the power system.

Since 2001, all vanadium flow batteries have truly entered the early stages of commercialization, mainly represented by American and Japanese companies in the early stages. The safety advantages over lithium batteries, the technological features that facilitate large-scale construction, and policy support are the main driving forces for the growth of all vanadium flow batteries at present.

Under multiple forces, the prospects for all vanadium flow batteries are relatively clear, and the relatively high cost in the early stages of commercialization is expected to be alleviated with the increase of projects, large-scale production, and technological breakthroughs. Liquid flow batteries have the characteristics of long lifespan, good safety, high output power, large energy storage capacity, and easy expansion, making them the optimal solution for energy storage in the long run.
