Battery performance continues to improve, and DTD (vinyl sulfate) application demand grows steadily

DTD (vinyl sulfate) is an SEI film-forming additive that can inhibit the initial capacity drop of the battery and the expansion of the battery after being cooked in a high-temperature room, and improve the battery charge-discharge performance and cycle times. In addition to being used in batteries, DTD can also be used as a pharmaceutical intermediate, and its application demand is high in hypertension drugs.

There are multiple DTD production methods. The current mainstream technologies include acylation method, substitution method, addition method, dioxane synthesis method, and oxidation method. Among them, oxidation method is currently the main applied production method. The DTD industry has been developing for a short period of time, and the current production technology is not yet mature. The above production methods each have their own advantages and disadvantages. As a new type of additive, DTD has low output and high production costs due to the immature production process, which hinders the development of the industry.

According to the “2022-2027 DTD (vinyl sulfate) industry market in-depth research and investment prospect forecast analysis report” released by the Industrial Research Center It shows that DTD is mainly used in ternary batteries to improve battery performance. It is expected that my country’s DTD market demand will be approximately 9,500 tons by 2022. As battery performance improves and the proportion of DTD added increases, the market demand for DTD will grow steadily, and the demand for DTD will reach 43,000 tons by 2025. The output of DTD is low and the production process requirements are high. The current product price is relatively expensive at 250,000/ton. It is estimated that the size of my country’s DTD market will be about 2.1 billion yuan in 2022. With the continuous development of the DTD industry, the price of DTD is also expected to decline. It is estimated that the size of my country’s DTD market will be approximately 6.5 billion yuan by 2025.

In terms of market competition, since 2018, my country’s DTD industry has developed rapidly and has gradually achieved domestic substitution. There are currently many companies in the DTD field, including Tianci Materials, Yanyi, Shi Dashenghua, Zhejiang Fuwei, Xinzhoubang, etc. Among them, Tianci Materials has a DTD production capacity of 1,000 tons and is still expanding its production. It is expected to have 1,000 tons of DTD by 2023. The production capacity is 7,000 tons; Shida Shenghua’s DTD production capacity is around 2,000 tons; Yanyi has a DTD production capacity of 3,000 tons.

With the expansion of production by leading enterprises, the production efficiency of individual devices has improved, achieving strong scale effects, and the leading pattern has become prominent. In terms of production technology, product purification, continuous production capabilities, and pollutant treatment capabilities will be improved in the future, production efficiency will be improved, and costs will decrease. In the future, the DTD industry will develop in the direction of being more environmentally friendly, simple to operate, high in safety, and high in yield.

Industry analysts people said that DTD, as a new additive, has good application prospects in batteries. With the development of my country’s power battery industry development, the demand for DTD applications is rising, and the industry has broad prospects for development. In terms of production, due to the complexity of DTD processing technology and the high industry threshold, there are currently few companies in this field, and the production capacity and output are low. However, in order to meet market demand, my country’s leading DTD companies have expanded production and gradually moved towards large-scale production, which is conducive to promoting the development of the industry.
