1. Multifunctional Electrolyte Additive for Lithium-Ion Batteries (Core Application)

- Flame Retardancy & Safety Improvement: As a main flame retardant in electrolytes, it significantly reduces the risk of battery combustion and explosion, especially suitable for power batteries of new energy vehicles and energy storage batteries.

- SEI Film Optimization: Synergizes with additives such as fluoroethylene carbonate (FEC) to form a more stable, low-impedance SEI film on silicon-based anodes, extending cycle life.

- Side Reaction Suppression: Reduces side reactions between electrolyte and electrode materials, lowers battery self-discharge rate, and enhances cycling stability at high temperatures (60°C).

- Wettability Improvement: Lowers electrolyte surface tension, improves wetting of electrode materials, and enhances rate performance.

- Applicable Systems: Ternary material batteries, lithium iron phosphate batteries, high-nickel batteries, silicon-carbon composite anode batteries, lithium-sulfur batteries, etc.

2. Other Application Fields

- Flame Retardancy for Polymer Materials: Used for flame-retardant modification of epoxy resins, polyurethanes and other materials to produce halogen-free flame-retardant electronic packaging materials and circuit board substrates.

- Organic Synthesis Intermediate: Used in the synthesis of functional compounds containing phosphazene rings, such as ionic liquids, surfactants and pharmaceutical intermediates.

- Electrochemical Sensors: Used as a modification material to improve sensor sensitivity and stability for environmental monitoring applications.
