Basf Investment lithium battery negative adhesive

Basf has announced that it will invest in the production of waterborne negative adhesives to support the lithium-ion battery industry by transforming two existing dispersion plants in Jiangsu and Guangdong provinces. The two units will produce two innovative negative adhesive products in addition to the existing portfolio. The project is expected to start production in mid-2023.

Although the negative electrode binder of lithium battery accounts for a small proportion in the battery material, it has an important impact on the performance and stability of the battery. Basf's innovative adhesive products can effectively increase battery capacity, improve cycle stability and reduce battery charging time. The investment is in line with the growing demand for lithium-ion batteries, especially in electric vehicles.

Basf's adhesives are designed to overcome the application limitations of lithium-ion batteries, including performance at low temperatures. They are water-based adhesives with high colloidal stability, good compatibility with carboxymethyl cellulose and other auxiliary adhesives, and excellent processing performance and coating performance. In addition, they have excellent mechanical and electrochemical properties.
