Could vanadium flow batteries revolutionize energy storage?

A new type of vanadium flow battery stack has been developed by a team of Chinese scientists, which could revolutionize the field of large-scale energy storage. Vanadium flow batteries are a promising technology for storing renewable energy, as they have long lifespans, high safety, and scalability.

Can a 70 kW-level stack promote the commercialization of vanadium flow batteries?

“This 70 kW-level stack can promote the commercialization of vanadium flow batteries. We believe that the development of this stack will improve the integration of power units in energy,” said Prof. Li Xianfeng, the leader of the research team.

What is Dalian flow battery energy storage peak shaving power station?

The power station is the first phase of the "200MW/800MWh Dalian Flow Battery Energy Storage Peak Shaving Power Station National Demonstration Project". It is the first 100MW large-scale electrochemical energy storage national demonstration project approved by the National Energy Administration.

How does a vanadium flow battery work?

The key component of a vanadium flow battery is the stack, which consists of a series of cells that convert chemical energy into electrical energy. The cost of the stack is largely determined by its power density, which is the ratio of power output to stack volume. The higher the power density, the smaller and cheaper the stack.

What is a vanadium / cerium flow battery?

A vanadium / cerium flow battery has also been proposed . VRBs achieve a specific energy of about 20 Wh/kg (72 kJ/kg) of electrolyte. Precipitation inhibitors can increase the density to about 35 Wh/kg (126 kJ/kg), with higher densities possible by controlling the electrolyte temperature.

Can vanadium ions penetrate a PFSA membrane?

However, vanadium ions can penetrate a PFSA membrane, a phenomenon known as crossing-over, reducing the energy capacity of the battery. A 2021 study found that penetration is reduced with hybrid sheets made by growing tungsten trioxide nanoparticles on the surface of single-layered graphene oxide sheets.
