CAS 33027-66-6 1,3,5,2,4,6-triazatriphosphorine, 2-ethoxy-2,4,4,6,6-pentafluoro-2,2,4,4,6,6-hexahydro-(PFPN)

Introduction

PFPN is a small molecule composed of nitrogen and phosphorus elements alternately forming a six-membered ring with five fluorine atoms and an ethoxy structure attached to it. Structurally, the six-membered ring skeleton has excellent flame retardant properties. At the same time, the five fluorine atoms attached to the six-membered ring can further improve the flame retardancy of PFPN and also play its advantages in electrochemistry.

Application 

Improved flame retardant performance: PFPN contains two flame retardant elements, phosphorus and fluorine, which can significantly improve the flame retardant effect of the electrolyte, enhance the safety of the battery, and prevent safety hazards such as fire and explosion caused by abuse or overcharging.
Optimized electrochemical performance: PFPN helps to form a stable solid electrolyte interface (SEI) film on the electrode surface, improve the compatibility between the electrolyte and the active material, and thus improve the cycle life and high-voltage performance of the battery.
High-efficiency flame retardant: PFPN, as a carbonization promoter, forms phosphorus-containing free radicals in a high-temperature combustion environment, exerts a gas-phase flame retardant effect, and also acts in the condensed phase to improve the flame retardant performance of the material
