Core Viewpoint - The article discusses the upcoming 2025 High-Performance Lithium Battery Annual Conference and the collaboration between a well-known cylindrical battery company and Jiangsu Yinglian Composite Current Collector Co., Ltd. to enhance the performance of composite current collector materials [2][3][4]. Group 1: Event Details - The 2025 High-Performance Lithium Battery Annual Conference will take place from November 18-20, 2025, at the JW Marriott Hotel in Shenzhen Qianhai [2]. - The event is organized by Gaogong Lithium Battery and Gaogong Industry Research (GGII), with various sponsors including HaiMuxing Laser and Dazhu Lithium Battery [2][3]. Group 2: Collaboration Overview - The partnership aims to integrate resources to improve the performance of composite current collector materials and optimize application solutions [3][4]. - Yinglian Composite Current Collector will provide core raw materials for research and experiments, while the battery company will implement and continuously optimize application solutions [4]. Group 3: Industry Trends - The composite current collector technology has faced challenges in commercialization over the past two to three years, but is now entering a critical development window in 2025 due to policy support and increased attention from the industry [4][5]. - The industry consensus indicates that composite aluminum foil has been gradually ramping up since 2022, and composite copper foil is expected to enter mass production in the second half of 2025 [4]. Group 4: Cost and Yield Improvements - Significant progress has been made in the production cost and yield of composite current collectors, with raw material costs for composite copper foil dropping to approximately 1.25 yuan/m², about one-third of traditional 6μm copper foil [5]. - Current yield rates for leading manufacturers of composite current collectors are around 80%, with some achieving over 95% for 6μm products, potentially leading to a 20% to 30% cost reduction compared to traditional copper foil [5]. Group 5: Policy and Standards Impact - The "Implementation Plan for High-Quality Development of the Copper Industry (2025-2027)" issued by multiple government departments highlights composite copper foil as a key development direction [6]. - New safety standards for electric vehicle batteries, effective from July 1, 2026, will enhance safety performance requirements, making composite current collector materials a crucial option to meet these standards [6][7].
