Chinese scientists develop organic molecules that are stable even when they come in contact with air in flow batteries.
Researchers at the Dalian Institute of Chemical Physics have developed novel naphthalene-based organic redox-active molecules for aqueous organic flow batteries. The newly developed ORAMs demonstrate that they can achieve stable cycling in normal ait-atmosphere condictions, a press release said.
This can increase the cost of battery maintenance since the capacity loss is irreversible and severely degrades the battery’s lifespan as well. The electrochemical step added another advantage since the researchers could now introduce hydrophilic alkylamine scaffolds into the naphthalene derivatives. This serves as protection from unintended side reactions while also improving the solubility of the molecules in the water-based electrolyte.
