Sodium iron phosphate pyrophosphate (NFPP)

This product, a sodium iron phosphate pyrophosphate cathode material developed for sodium-ion battery research, belongs to the polyanion family and exhibits excellent cycling stability. Due to its strong hygroscopic nature, the material requires strict handling conditions, including vacuum-sealed storage and a production environment with a dew point below -30 °C. Electrode preparation involves baking at 105 °C for 4 hours, and electrochemical testing is typically performed using a dedicated sodium-ion electrolyte (e.g., KLD-NC06). Commonly employed in half-cell evaluations for cathode performance screening and fundamental studies, this material is well-suited for researchers investigating high-cycle-life polyanion cathodes. It is supplied in various quantities (20 g to 1 kg) and must be kept sealed in a cool, dry place to maintain its properties.
