Upcoming Seminar on Dry LIB Manufacturing Trends

The Institute of IR Engineers is set to hold a comprehensive seminar focused on the latest developments in the manufacturing processes for dry lithium-ion batteries (LIB) on April 22, 2026. This seminar aims to provide a structured overview of the current trends and practical challenges associated with dry process manufacturing, which excludes the use of solvents, thus offering a significant advantage in performance and productivity.

Background of the Seminar

As the demand for high-performance and highly productive batteries continues to rise, traditional wet processes, which are predicated on solvent usage, have become increasingly limiting due to restrictions in both equipment and operational aspects. In response to these challenges, the dry process has gained popularity as a viable alternative for electrode production, allowing for broader choices in manufacturing approaches. However, implementing dry processes brings its own set of challenges, including material design, mixing, film strength, and handling issues, which must be addressed comprehensively during the seminar.
