J. Electrochem. Soc., 161 ( 2014), pp. A1381 - A13A7 Shunt currents can hinder the performance and reduce the lifespan of redox flow batteries. This work focuses on finding the best approach to mitigate
The shunt current depends on the resistance of the electrolyte (R) for the ions to flow from one cell to adjacent cell and it is defined by following equation, where is the resistivity, = length of the channel, = area of the cross section of the channel.
Consequently, the flow frame channels and the manifolds of a stack become pathways for charged ions to migrate from high potential to low potential cells, forming shunt currents . The latter makes the current in each cell of the stack to decrease during charging and increase during discharging steps .
Our BESS energy storage systems and photovoltaic foldable container solutions are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
