Core Viewpoint - Conductive carbon aluminum foil is a modified current collector that reduces contact resistance between current collectors, collects microcurrents of active materials, and improves battery performance, including charge-discharge rates and cycle life [1][2]. Group 1: Material Characteristics - Conductive carbon aluminum foil is produced by coating a uniform layer of conductive materials (such as carbon black, graphite, and graphene) on the surface of aluminum foil, resulting in a more uniform surface compared to traditional aluminum foil [1]. - It enhances the conductivity of the positive electrode, reduces internal resistance, and improves adhesion between active materials and current collectors, primarily used in lithium iron phosphate batteries [1][2]. Group 2: Market Analysis - The global market for conductive carbon aluminum foil is projected to reach $1.115 billion in 2024, with a compound annual growth rate (CAGR) exceeding 50% from 2020 to 2024, and China is expected to account for 79% of global sales in 2024 [4]. - By 2027, the market is anticipated to grow to $3.219 billion, with a CAGR of 15.23% from 2025 to 2031 [13]. Group 3: Industry Trends - The thickness of positive aluminum foil has decreased from 16μm to 10μm, with some manufacturers even using 8μm, while negative copper foil has seen a reduction from 12μm to 6μm, indicating a trend towards lighter battery components [3]. - Future coating materials are expected to diversify, with graphite coatings offering higher conductivity and flexibility, gradually replacing carbon black products [5][6]. Group 4: Application Expansion - Conductive carbon aluminum foil is expanding beyond lithium-ion batteries to applications in supercapacitor bipolar plates, sodium-ion batteries, solid-state batteries, and flexible electronic devices [8][9][10]. - The material is particularly suited for high-performance applications due to its ability to enhance conductivity and mechanical strength [6]. Group 5: Policy Support - China's commitment to peak carbon emissions by 2030 and achieve carbon neutrality by 2060 is driving the rapid development of new energy vehicles and storage systems, creating significant market opportunities for conductive carbon aluminum foil [18]. - Policies supporting the commercialization of energy storage systems and the domestic production of key materials are expected to further boost the industry [18].
