Description

General description

1.0 M NaPF₆ in EC/DEC=50/50 (v/v) consists of a 1.0 M concentration of sodium hexafluorophosphate (NaPF₆) dissolved in a 1:1 volume ratio of ethylene carbonate (EC) and diethyl carbonate (DEC). The product is a clear solution with strictly minimized impurities including low moisture, low trace metals, low chloride, and low sulfate.

Application

The main application of 1.0 M NaPF₆ in EC/DEC=50/50 (v/v), battery grade is as an electrolyte in sodium-ion batteries (NIBs) Studies have found that when NaPF₆ in a mixture of ethylene carbonate and diethyl carbonate (EC:DEC (1:1 v:v)) used as electrolyte in sodium-ion batteries (SIBs), there is an increase of the ionic conductivity, the cation transference number, and the binary diffusion coefficient thereby increasing the power density NaPF₆ in EC/DEC can provide a stable and effective electrolyte solution that helps form a protective solid electrolyte interface (SEI) on the electrode surfaces, which reduces electrode breakdown and improves overall battery performance
