16 million!

Recently, Lihua Yiweiyuan Chemical Co.
, Ltd.
issued an announcement: the company signed the "20,000 tons/year high-purity dimethyl carbonate technology license agreement" with Japan's Ube Industrial Co.
, Ltd.
The technology for producing high-purity dimethyl carbonate from ester was licensed to the company, and the license fee totaled 300 million yen (ie 16.
3989 million yuan, estimated at the current exchange rate)
.

Entering the field of electrolytes

The 20,000-ton/year high-purity dimethyl carbonate production capacity is part of the company's fundraising project "100,000-ton/year high-purity dimethyl carbonate project"
.
If the agreement is fulfilled in place, the company will add high-purity dimethyl carbonate products, further enriching the company's product structure, marking an important step forward for the company in the field of lithium battery electrolyte, enhancing the company's competitiveness, and contributing to the company's annual output of 20,000 tons The production capacity of the high-purity dimethyl carbonate plant has a long-term and positive impact
.

Dimethyl carbonate is a new chemical that has attracted much attention in the chemical industry at home and abroad in recent years.
Because of its wide range of uses, it is known as the "new cornerstone" of today's organic synthesis
.
High-purity dimethyl carbonate (referred to as "HPDMC") is mainly used in lithium battery electrolyte.
As one of the four key materials of lithium battery, electrolyte is mainly used in three fields of new energy vehicles, 3C digital and energy storage
.

Lithium battery electrolyte is mainly composed of solvent, additives and electrolyte, among which solvent accounts for about 80% of the electrolyte quality and is the main raw material of electrolyte
.
According to data from the Lithium Battery Research Institute (GGII) of the High-tech Industrial Research Institute, China will ship 500,000 tons of electrolytes in 2021, a year-on-year increase of 100%
.
With the continuous expansion of downstream demand, further growth is expected in the future
.

Domestic dimethyl carbonate (DMC) production capacity

By the end of 2021, the national dimethyl carbonate (DMC) production capacity totaled 1.
256 million tons per year, of which industrial-grade production capacity accounted for over 80%
.
On the one hand, the demand for industrial-grade DMC occupies a dominant position in the total demand; on the other hand, battery-grade DMC has high requirements for purity, and the corresponding process requirements are relatively high.
Mainly, there are very few companies producing battery grade DMC
.

At present, there are only 4 domestic companies that have mastered the battery-level DMC process, namely Shi Dashenghua, Shandong Haike, Aoke Co.
, Ltd.
and Anhui Zhongyan Red Sifang.
Among them, the leading enterprise Shidashenghua accounts for more than 60% of the current battery-level DMC production capacity
