Description

Description générale

Fluoroethylene carbonate (FEC), Technipur^®is a fluorinated cyclic carbonate, that comes in powder/crystal or chunk form with white in color. It has a purity of ≥99% and is designed to address R&D activities in the ongoing development and optimization of high-performance batteries. It is soluble in many organic solvents such as dimethyl carbonate (DMC), ethylene carbonate (EC), and diethyl carbonate (DEC). For smaller SKUs, visit 757349

We are committed to bringing you Greener Alternative Products, which belongs to one of the four categories of greener alternatives. Fluoroethylene carbonate is an enabling product, used as an electrolyte additive and is helpful to improve the performance of batteries, thus has been enhanced for energy efficiency.

Application

Fluoroethylene carbonate (FEC) is extensively used as a film-forming electrolyte additive in lithium-ion batteries, where it facilitates the formation of a stable, lithium fluoride (LiF)-rich solid electrolyte interphase (SEI); which is insoluble in the electrolyte; in turn increasing the cycling efficiecny and discharge capacity retention of the secondary battery. Experiments concluded that use of fluorinated solvents or other performance additives such as FEC in the electrolyte can improve the low temperature performance, oxidation resistance, flame retardancy and wettability of the electrode. In another experiment, it has been found that the freestanding Si-carbon nanotubes (CNTs) composite paper anodes for Li-ion batteries achieve higher specific capacity and better capacity retention in terms of long-term cycling when FEC (10 wt%) is used as an additive.[1][2][3]
