In the rapidly evolving landscape of battery technology, optimizing the processes of coating, drying, post-drying and the overall humidity management holds paramount importance for enhancing the performance, reliability, and cost effectiveness of battery systems. This talk explores the latest advancements and persistent challenges in these critical stages of battery manufacturing. Coating techniques such as roll-to-roll slot-die coating have seen significant advancements, enabling control over electrode thickness and edge elevations, adjusting film morphology by simultaneous multi-layer coating, and meet special product demands by high-speed intermittent and stripe coating. For simultaneous double-layer coating, also tensioned-web coating is under investigation. Many of these coating-related approaches have led to improved electrode properties, contributing to enhanced energy density and cycling stability.
However, challenges persist in achieving uniform coatings, especially for multi-layers and simultaneous double-sided coatings, and ensuring compatibility with various electrode formulations. Drying and post-drying processes play a crucial role in removing solvents, forming solid electrolyte interfaces (SEI), and controlling microstructure, directly impacting battery performance and safety.
Recent developments in drying technologies, including hot-air, infrared, laser and inductive drying, have shown promise in achieving faster drying rates while minimizing undesired binder migration and improving energy efficiency. Additionally, an advanced understanding of post-drying and humidity management should help to lower the overall production costs of battery cell manufacturing.
Nevertheless, challenges remain in scaling up these processes to industrial levels, ensuring reproducibility, and minimizing environmental impacts. Addressing these challenges requires interdisciplinary efforts involving materials science, engineering, and process optimization.
This talk will give an overview about latest research findings, technological innovations, and future prospects in coating, drying, post-drying techniques for battery applications and humidity management aspects. By shedding light on both recent advancements and ongoing challenges, this talk aims to inspire collaborative efforts and drive further innovation in the field of battery manufacturing.
