Chloroethylene Carbonate

Electrolyte additive for lithium-ion batteries, from a dedicated 40,000 t/y line

Chloroethylene carbonate (CEC) is used as an electrolyte additive for lithium-ion batteries and as an organic synthesis intermediate. High-purity grade serves directly as a flame-retardant additive that improves the cycle performance and service life of battery electrolyte. Gaoyuan commissioned a dedicated CEC line in 2022.

  • High-purity grade for direct flame-retardant use

Concentration, grade and packaging are set to your specification. Tell us the end use and the market, and we will confirm which grade applies and what documentation comes with it.

Applications

Where this chemistry actually gets used.

Every field below has different purity and documentation requirements. Tell us which one you are in and we will confirm the grade before quoting.

Lithium-ion battery electrolyte additive

The main use. Improves the cycle performance and service life of battery electrolyte.

Flame-retardant additive

High-purity grade can be used directly as a flame-retardant additive without further processing.

Organic synthesis intermediate

Intermediate in fine chemical and pharmaceutical synthesis routes.

Specification

Identification and properties.

Assay and impurity limits follow Manufacturer specification and the grade ordered. We send the full specification sheet and a batch certificate of analysis on request.

Purity

Full specification
Purity and impurity limits depend on the grade ordered — battery grade and high-purity grade differ. Request the specification sheet and a batch COA below.

Packaging

How it ships.

Standard export packing is listed here. Drum size, concentration and drum marking are all changed to your specification.

  • Drummed; sealed under an inert atmosphere
  • Packaging format and grade to customer specification

Customisation

  • 01Purity grade to your electrolyte formulation
  • 02Packaging format and drum size

Storage & handling

Read this before the first container lands.

A safety data sheet is issued with the order. The points below are the ones that most often get missed on a first purchase, so they are on the page rather than in an annex.

Storage & transport

  • 01Store sealed, under an inert atmosphere, protected from light
  • 02Keep away from water and strong acids — both cause decomposition
  • 03Store at ambient temperature in a well-ventilated area

Health hazards

  • 01Corrosive to skin; severely irritates the eyes and respiratory mucosa
  • 02Ingestion causes burns to the oesophagus and gastric lining
  • 03Long-term inhalation of vapour may lead to rhinitis, bronchitis and emphysema
  • 04Operators must wear chemical-resistant gloves and gas masks, and ensure adequate ventilation in the working area

Documents

What we send with a quotation.

Which documents apply depends on your market and end use, so we confirm the destination before sending. Sodium chlorite for drinking water, for textile bleaching and for flue gas treatment are three different conversations.

  • Product specification sheet for the grade quoted
  • Batch certificate of analysis (COA)
  • Safety data sheet (SDS)
  • ISO 9001, ISO 14001 and ISO 45001 certificates
  • NSF listing and EU REACH registration, where they apply to your market
