Low cost electrode decoupled redox flow batteries for grid-scale energy storage
Ramani, Vijay ; Sankarasubramanian, Shrihari
T-018530

— Technology Description Engineers in Prof. Vijay Ramani’s laboratory have developed an electrode decoupled redox flow battery (RFB) with stable electrolyte materials that can generate power densities comparable to all-Vanadium RFBs at less than half the cost. RFBs are a promising option for …

A Highly Efficient Brine Electrolyzer
Gayen, Pralay ; Ramani, Vijay ; Sankarasubramanian, Shrihari
T-019234

— Technology Description Researchers in the Ramani lab at Washington University have developed an electrolyzer capable of selectively splitting salty or brackish water into ultra-pure hydrogen and oxygen at high operating power densities. Originally designed to tap the perchlorate-rich water on the …

High Performance Direct Methanol and Direct Ethanol Fuel Cells with Microscale Bipolar Interface
Ramani, Vijay ; Sankarasubramanian, Shrihari ; Wang, Zhongyang
T-019124

— Technology Description Engineers in Prof. Vijay Ramani’s laboratory have developed a biopolar interface membrane to prevent fuel crossover and improve the performance of direct methanol and direct ethanol fuel cells (DMFC and DEFC). This membrane separator is designed to maintain a steep pH …
