The prosperity of the new energy automobile industry continues to increase, and the market demand for vinylene carbonate (VC) is becoming increasingly strong.

Vinylene carbonate (VC), also known as ethylene carbonate and 1,3-dioxol-2-one, has a chemical formula of C3H2O3 and is an organic compound. Vinylene carbonate appears as a colorless and transparent liquid with relatively stable chemical properties. According to different uses, vinylene carbonate can be divided into electronic grade and industrial grade.

Vinylene carbonate has a wide range of applications, including lithium battery electrolyte, surface coatings, biomedicine, etc. In the field of lithium battery electrolyte, vinylene carbonate, as an organic film-forming additive, can effectively improve the charge and discharge efficiency and cycle characteristics of lithium-ion batteries. At present, vinylene carbonate has become the mainstream additive for lithium battery electrolytes, accounting for nearly 40.0% of its production costs. In recent years, benefiting from the increasingly strong market demand for new energy vehicles, lithium battery shipments have increased significantly, which will provide broad space for the development of the vinylene carbonate industry.

According to the “2022-2027 Vinylene Carbonate Industry In-depth Market Research and Investment Strategy Suggestions Report released by the Industrial Research Center, Due to the reduction in the supply of vinylene carbonate in my country, its market price has rebounded, and the market size has shown a continued growth trend. In 2021, my country’s vinylene carbonate market size will reach 1.05 billion yuan, a year-on-year increase of 39.5%. Currently, South China and East China are the largest consumer markets for vinylene carbonate in my country, accounting for 70.0% of the market size.

The production process of vinylene carbonate mainly adopts the synthesis method, using ethylene carbonate as the raw material, using sulfonyl chloride as the chlorinating agent to generate monochloroethylene carbonate, and then undergoing a dehalogenation reaction to finally produce vinylene carbonate. The synthesis method is prone to produce toxic gases such as chlorine. Affected by factors such as national environmental protection policies and the deepening of supply-side structural reforms, the production of vinylene carbonate in my country has become more difficult in recent years, resulting in a gradual decline in output. In 2021, my country’s vinylene carbonate output reached 3215.7 tons, a year-on-year decrease of 9.6%.

Zhejiang Yongtai Technology Co., Ltd., Jiangsu Huasheng Lithium Battery Materials Co., Ltd., and Shenzhen Xinzhoubang Technology Co., Ltd. are the main manufacturers of vinylene carbonate in my country. Huasheng Lithium Battery occupies a leading position in my country’s vinylene carbonate and fluoroethylene carbonate (FEC) markets, and the company’s products are widely used in photovoltaic power stations, power tools, new energy vehicles and other fields. According to the annual report of Huasheng Lithium Battery Company, the company achieved revenue of 1.0 billion yuan in 2021, a year-on-year increase of 124.0%.

Industry analysts said that vinylene carbonate, as an important organic synthesis intermediate and basic chemical raw material, has been widely used in many fields. As the prosperity of the new energy vehicle industry continues to improve, the market demand for vinylene carbonate will continue to grow. my country’s vinylene carbonate production technology has matured. Under the influence of positive factors such as the deepening of environmental protection concepts, the industry will develop in a green direction.
