Ammonium polyphosphate (APP, (NH4PO3)n) is a novel multifunctional inorganic aqueous binder that is gaining significant attention in battery research, particularly for Lithium-Sulfur (Li-S) and phosphorus-based batteries. APP is water-soluble, which allows battery manufacturers to avoid toxic and expensive organic solvents like NMP, making the fabrication process "greener" and more cost-effective.
(1) In Lithium-Sulfur batteries, soluble lithium polysulfides (Li2S) often migrate (the "shuttle effect") and degrade the battery. The polar N-H and P-O groups in APP have a strong chemical affinity for these polysulfides, trapping them at the cathode to extend cycle life.
(2) APP is an industrial-grade flame retardant. When used as a binder, it significantly reduces the flammability of the sulfur cathode or phosphorus anode, providing a built-in safety mechanism against thermal runaway.
