مدلسازی وابسته به زمان و تحلیل فنی باتری جریانی اکسایشی-کاهشی وانادیومی با غشاء پلیمری

The mentioned paper provides a new approach in the design, modeling and evaluation of vanadium redox flow batteries with polymer membrane. Vanadium redox flow batteries have been proposed as one of the advanced technologies in energy storage systems. This study is based on transient conditions of performance modeling of a battery cell. The proposed time-dependent model has developed based on comprehensive electrochemical, mechanical, fluid and electrical circuit relations along with the concept of taking reasonable assumptions, constraints and appropriate boundary conditions. The results of modeling explain the behavior of different variables such as the concentration of vanadium oxides, the rate of state of change and produced voltage in the battery operating time. On the other hand, the performed parametric study on battery variables represents a significant effect on temperature and initial concentration of the electrolyte solution on the output voltage.
