COST EFFECTIVE BATTERY MEMBRANES To Improve Electrochemical Energy Storage Performance BERKELEY LAB EXPERTISE NANOTECHNOLOGY ©Nanosys, Inc. BIOENGINEERING BATTERIES 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.
