Fluoroethylene Carbonate (FEC) Supplier in Malaysia
- Also known as
- FEC
- 4-Fluoro-1,3-Dioxolan-2-One
Fluoroethylene carbonate supplier for lithium-ion electrolyte and cell manufacturers in Malaysia. Better known as FEC and also written 4-fluoro-1,3-dioxolan-2-one, this fluorinated cyclic carbonate carries the CAS number 114435-02-8. Its job in a cell is to support a stable and elastic interphase on the anode, which is why it is specified in chemistries using high-nickel and silicon-bearing electrodes.
The fluorine substituent is the point of the molecule: it alters how the carbonate reacts at the electrode surface and produces a tougher film than unfluorinated carbonates. Commercial grades are a battery electrolyte additive grade, a high-purity research grade and a standard industrial grade, separated on assay, water and impurity limits. FEC is a clear liquid at ordinary room temperature but tends to solidify below about 20 degrees Celsius.
Typical use is in electrolyte formulation for consumer, electric-vehicle and stationary energy-storage cells, plus development and prototyping work. It is not ethylene carbonate or vinylene carbonate, which are separate additives with their own pages.
Send the required grade, any purity or water limit, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation. Supply is subject to applicable requirements.

Common questions about fluoroethylene carbonate
What does fluoroethylene carbonate do in a lithium-ion cell?
FEC is a fluorinated cyclic carbonate used as a film-forming additive in lithium-ion electrolytes. It helps build a stable and elastic passivating layer on the anode, which matters especially when the electrode contains high-nickel or silicon material.
Why is the fluorine substituent important?
The fluorine atom changes how the carbonate decomposes at the electrode, supporting a tougher, more stable interphase than unfluorinated carbonates. That is the reason FEC is specified in demanding cell chemistries.
Is fluoroethylene carbonate the same as ethylene carbonate?
No. Ethylene carbonate carries no fluorine and has its own page, while fluoroethylene carbonate is the fluorinated version with different interphase behaviour. Do not substitute one for the other in a formulation.
Is fluoroethylene carbonate the same as vinylene carbonate?
No. FEC is fluorinated while vinylene carbonate is an unsaturated carbonate, and the two behave differently as additives. Each has its own page, so order the additive named on the formulation by name.
How should fluoroethylene carbonate be handled in storage?
Keep containers sealed in a cool place and check the safety data sheet for the quoted grade. FEC can solidify when the ambient temperature drops, so warming may be needed before use.
What is needed for a fluoroethylene carbonate quotation?
Provide the grade, any purity or water limit, quantity, delivery location and preferred packing. The offer and its validity period are confirmed on enquiry.
