平面红外干燥：锂电前段成本新解

Core Viewpoint - The article discusses the advancements in drying technology for lithium battery manufacturing, particularly focusing on the transition from traditional hot air drying systems to new infrared drying systems, which promise significant energy savings and efficiency improvements [4][10]. Group 1: Current Challenges in Drying Technology - The traditional hot air drying systems are large, often occupying over 4000 square meters, and involve significant investment in auxiliary systems like boilers and heat exchange equipment [5][6]. - The drying process accounts for approximately 15% of the overall carbon emissions in lithium battery production, with potential carbon tax costs reaching nearly $600 million at a carbon price of $25 per ton [6][10]. Group 2: Innovations in Infrared Drying Technology - The new infrared drying system developed by Reso New Materials utilizes self-developed graphene materials as a heat source, achieving over 80% infrared conversion efficiency and operating effectively at temperatures between 200 and 300°C [7][8]. - Key benefits of the infrared system include over 50% energy savings, a 40% increase in drying efficiency, and a reduction in oven length by 30% to 50%, leading to lower construction and integration costs [7][8]. Group 3: Implementation and Future Prospects - Since 2022, Reso has delivered over 200 infrared systems, with applications across various stages of battery production, including negative electrode coating and separator coating [8][9]. - The infrared system is designed to operate independently without auxiliary heat sources, making it particularly suitable for projects with space constraints or stringent carbon emission requirements [9][10].
