Analysis on the development status and prospects of China’s SBR (styrene-butadiene latex) negative electrode binder market in 2023

China's SBR (styrene-butadiene latex) negative electrode binder market development status and prospect analysis in 2023

Lithium battery binder is a material used to connect electrode active materials, conductive agents and electrode current collectors to create a good conductive network between materials and stabilize the internal structure of the pole piece. Binders can be divided into oil-based binders and water-based binders according to different solvents. Water-based binders have the advantages of safety, environmental protection, and high cost performance. SBR (styrene-butadiene latex) negative electrode binder is a type of water-based negative electrode binder. The SBR latex particle unit has a core-shell structure. The shell is a cross-linked structure of copolymer molecular chains, and the outer shell is a hydrophilic polar groups and surfactants. SBR (styrene-butadiene latex) negative electrode binder has high bonding strength and good mechanical stability, and is widely used in the industrial production of graphite negative electrodes.

SBR (styrene-butadiene latex) is mainly used in the production of tires, rubber machinery products, shoes and other products. SBR used in the negative electrode binder field accounts for a relatively small proportion. However, due to the slow growth in the automobile, tire, shoemaking and other industries in recent years, lithium batteries The sustained and rapid development of the industry has driven the growth of the market demand for SBR negative electrode binders, and the proportion of SBR used in the negative electrode binder field has also increased.

According to data released by the Electronic Information Department of the Ministry of Industry and Information Technology, national lithium-ion battery production will reach 750GWh in 2022, a year-on-year increase of more than 130%; anode material output is approximately 1.4 million tons, a year-on-year increase of more than 60%. The output of lithium-ion batteries has continued to grow rapidly in recent years, driving the growth of China’s SBR anode binder market. In 2023, China’s SBR negative electrode binder market size will exceed 2 billion yuan.

The “2023-2028 China SBR (styrene-butadiene latex) negative electrode binder industry market in-depth research and development prospect forecast report compiled and released by the Industrial Research Center 》shows that for a long time, the SBR negative electrode binder market has been dominated by imported products, and the key companies are mainly Japan’s Zeon, Japan’s JSR, Japan’s A&L, and Germany’s BASF. Japan’s Zeion is the world’s leader in water-based negative electrode binders. It is the world’s first enterprise to develop, produce and sell water-based negative electrode binders, with a high market share. In recent years, with the rapid development of the lithium-ion battery industry, there have been many related industrial chain layouts. Currently, SBR negative electrode binders have been domestically produced, and Jingrui Electric Materials has certain competitiveness in the global SBR negative electrode binder field.

Jingrui Electric Materials is a platform-based high-tech enterprise in electronic materials, focusing on the two directions of pan-semiconductor materials and new energy materials. Its leading products include high-purity chemicals, photoresists, lithium battery materials, industrial chemicals and energy, etc. Lithium battery binder products include SBR, CMCLi, PAA, etc., with an annual negative electrode binder production capacity of 37,000 tons. The CMCLi binder developed by Jingrui Electric Materials has been successfully mass-produced. Compared with the traditional CMCNa binder, this product can improve the first-efficiency performance, better low-temperature performance and cycle life.

It is expected that in the next few years, driven by the growth of the lithium-ion battery market, the market size of China’s SBR anode binder products is also expected to continue to grow, and the number of companies will further increase.
