PAIN POINT
Redox-flow batteries have the potential to provide low cost, multi-hour energy storage but are
limited by redox active species migrating across the ion-transporting membrane and shorting the
SEMICONDUCTORS
battery. The cost of battery membranes on the market limits commercial deployment.
SOLUTION
Mechanically robust ion- and size-selective membranes from Berkeley Lab offer the possibility of
ENERGY EFFICIENCY
more reliable, efficient, and high power electrochemical energy storage grids at extremely low cost.
