Principle of vanadium battery temperature control technology

Why is temperature control important for vanadium redox flow batteries?

Vanadium redox flow batteries not only require paying attention to the problems of excessive temperature of the electrolyte, but also precipitation occurs at lower temperatures. Therefore, temperature control is very important for these types of batteries.

What is a vanadium redox flow battery?

Vanadium redox flow batteries are recognized as well-developed flow batteries. The flow rate and current density of the electrolyte are important control mechanisms in the operation of this type of battery, which affect its energy power. The thermal behavior and performance of this battery during charging and discharging modes are also important.

How does temperature affect the temperature distribution of a battery?

The main results of this investigation are: The temperature of the battery increases with boosting the working temperature. However, the temperature distribution of the battery with an working temperature of 40 °C in the discharge state is less uniform, resulting in localized heating spots.

Can machine learning be used for thermal management of vanadium redox flow batteries?

Machine learning algorithm is employed for the prediction and optimization in various systems [ 45, 46, 47 ]. This algorithm can also be employed for the thermal management of vanadium redox flow batteries. Sohani A, Cornaro C, Shahverdian MH, Pierro M, Moser D, Nižetić S, Karimi N, Li LKB, Doranehgard MH.

How does working temperature affect battery performance?

The temperature of the battery increases with boosting the working temperature. However, the temperature distribution of the battery with an working temperature of 40 °C in the discharge state is less uniform, resulting in localized heating spots. The working temperature affects the voltage performance of the battery.

How does temperature affect a flow battery?

The temperature of the flow battery increases by changing the working temperature from 10 to 40 °C. It may be due to the fact that an increase in working temperature has a considerable effect on the electrochemical activity, charge, and mass transport of the electrolyte [ 27 ].
