"Phosphorus, Sulfur, and Aluminum: Advancements in Sustainable Redox Flow Batteries"

Researchers have developed a proof-of-concept for a new class of molecules based on main group elements, specifically phosphorus and sulfur, that can efficiently store and release energy in redox flow batteries. This discovery offers potential for improving energy storage from intermittent sources like solar and wind. The molecules, called terthiophenes, demonstrated high stability and the ability to store electrons at extreme potentials. While solubility remains a challenge, further modifications to the structure are expected to increase solubility, energy density, and robustness. This research opens up possibilities for using organic systems in flow batteries and reducing reliance on scarce materials and corrosive compounds.
