Description

General description

Ammonium dihydrogenphosphate is a white crystalline solid widely applied in rechargeable batteries, non-linear optics, and fire-retardant coatings. It is insoluble in ethanol and acetone.

Application

Ammonium dihydrogenphosphate can be used:

• As a precursor to fabricate cathode materials for Li-ion batteries to enhance cyclic performance.
• As an electrolyte additive in rechargeable batteries to enhance the ionic conductivity or to reduce the risk of side reactions within the electrolyte.
• To fabricate flame-retardant polymer composites.
