What's Happening?
Researchers have developed hydroquinone-substituted polyallylamine (PDA) as a promising material for aqueous polymer-air secondary batteries. The synthesis involves condensing 2,5-dihydroxybenzoic acid with polyallylamine, resulting in a polymer with adjustable substitution levels. PDA exhibits excellent electrochemical properties, including high capacity and cyclability, making it suitable for use in rechargeable batteries. The polymer's improved hydrophilicity and electrostatic repulsion allow for efficient charge storage, achieving close to theoretical capacity even at high discharge rates. Additionally, PDA can be decomposed into raw materials through acid hydrolysis, offering a sustainable solution to plastic pollution.
