Sigma-Aldrich LITHIUM HEXAFLUOROPHOSPHATE SOLUTION IN&

Our 1.0 M LiPF₆ in EC/EMC=30/70 (w/w) with 1 wt.% VC is a battery-grade electrolyte designed for use in lithium-ion batteries. This electrolyte contains a 1.0 M concentration of lithium hexafluorophosphate in a mixture of ethylene carbonate and ethyl methyl carbonate with a vinylene carbonate additive. Our electrolyte is highly pure with carefully minimized impurities of water, acid, and metals. It is safely packaged in an aluminum bottle under inert, dry conditions.

Our battery-grade 1.0 M LiPF₆ in EC/EMC=30/70 (w/w) with 1 wt.% VC electrolyte is optimized for safety, thermal stability, and performance for lithium-ion batteries. The 30/70 blend of EC/EMC combines the high dielectric constant of ethylene carbonate and the low viscosity of ethyl methyl carbonate to afford an electrolyte with a wide electrochemical stability window and excellent wetting. The vinylene carbonate additive helps to form a passivating solid-electrolyte interface (SEI), which improves the electrochemical performance at higher working temperature and resists thermal damage[1][2] Our electrolyte is compatible with a wide range of cathode and anode materials, including graphite, lithium-metal, LFP, and NMCs making it ideal for use in many battery applications[3]
