Scientists from Skoltech have developed a new model that simplifies the creation and use of vanadium flow batteries. These industrial energy storage devices can play an important role in the transition to electric vehicles and renewable energy sources. Such batteries are already actively used in China, Germany and the USA to offset peak loads in power grids. Experts are confident that without technologies like these, a major transition to clean energy would be impossible.
According to Mikhail Pugach, a senior researcher at Skoltech, vanadium flow batteries have two electrodes and an electrolyte, but unlike lithium-ion batteries, the chemical reaction that provides the energy takes place in a liquid electrolyte. Although these drives are bulkier and heavier than traditional batteries, they have a number of advantages: greater capacity, durability and flexibility in use. Moreover, vanadium batteries charge quickly, do not pose a fire hazard and do not require imported materials.
The new model can accurately predict how a battery will perform without needing a lot of membrane data. This greatly simplifies the process of developing and maintaining drivers. Sergei Parsegov, co-author of the study, noted that the model helps select optimal materials, which increases reliability and slows down the degradation of the container. It also tells you when to make changes to your electrolyte to help maintain its effectiveness. In this way, Skoltech’s development opens up new opportunities for efficient energy storage and better operation of critical infrastructures such as nuclear power plants and data centers.
