2025高工新能源新材料产业大会 | 英联复合集流体将作主题演讲

Core Viewpoint - The 2025 High-Performance New Energy Materials Industry Conference will focus on the acceleration of composite conductive materials in the lithium-ion battery sector, highlighting the strategic partnership between Yinglian Composite Conductive Materials and a leading global polymer lithium-ion battery manufacturer [1][2]. Group 1: Industry Developments - The composite conductive materials industry is experiencing accelerated industrialization, with Yinglian's partnership with a top consumer battery manufacturer seen as a key move into the consumer electronics lithium battery supply chain [1]. - Yinglian's new factory in Jiangsu is set to produce 1 billion square meters of composite aluminum foil and 5 billion square meters of composite copper foil, positioning the company among the global leaders in production capacity [2]. Group 2: Technological Innovations - Yinglian's core products utilize a "PET base film + metal layer" sandwich structure, achieving significant technical breakthroughs with a metal layer thickness of only 2.5μm for composite copper foil and 4.5μm for composite aluminum foil [2]. - The safety of Yinglian's composite conductive materials has been enhanced, passing 100% puncture tests to ensure they do not smoke, catch fire, or explode [2]. - The lightweight design of the battery system has resulted in a 13.8% increase in energy density [2]. Group 3: Reliability and Manufacturing Solutions - The corrosion rate of composite copper foil after 72 hours of immersion at 80℃ is consistent with traditional copper foil, while composite aluminum foil shows no corrosion after 120 hours in electrolyte at 85℃, meeting the durability requirements for power batteries [3]. - Yinglian has validated dual solutions for welding challenges in composite conductive materials, focusing on material thinning and ultra-thin material welding to address process compatibility issues [4].
