Description

Lithium Difluorophosphate (LiPO2F2) is a high-purity inorganic compound with the molecular formula F2LiO2P, widely recognized for its critical role in advanced lithium-ion battery technologies. This white crystalline powder, with CAS number 24389-25-1, is synthesized under stringent conditions to ensure optimal electrochemical performance. As a key electrolyte additive, it enhances the stability and efficiency of lithium-ion batteries by improving the solid-electrolyte interphase (SEI) layer, particularly under low-temperature conditions. Its IUPAC name, lithium;difluorophosphinate, reflects its precise chemical structure, while its synonyms (e.g., Lithium phosphorodifluoridate, MFCD32670669) cater to diverse industrial and research applications. Packaged under inert conditions to prevent degradation, this product is ideal for researchers and manufacturers seeking to optimize battery longevity, reduce self-discharge, and minimize reliance on traditional additives like LiPF6.

Application

Lithium Difluorophosphate (LiPO2F2) is primarily used as an electrolyte additive in lithium-ion batteries to enhance low-temperature performance by reducing SEI layer resistance. It significantly lowers battery self-discharge rates while enabling reduced consumption of LiPF6, improving cost-efficiency. Its application extends to high-energy-density batteries for electric vehicles and portable electronics, where stable cycling and extended lifespan are critical.
