“电池保镖”大规模量产要来了？可川科技募资5亿元生产复合铝箔，已询价国内设备商

Core Viewpoint - The recent recall of power banks from Roma and Anker has heightened consumer concern over battery safety, leading to increased attention on composite current collectors, which enhance battery safety [1][2] Group 1: Composite Current Collectors - Composite current collectors consist of composite copper foil and composite aluminum foil, with the latter being the focus of Kewan Technology's large-scale production plans [3] - Kewan Technology aims to raise up to 500 million yuan for its "New Composite Materials for Lithium Batteries Project (Phase I)," with a total investment of 748 million yuan, targeting an annual production capacity of 95 million square meters of composite aluminum foil upon full production [3] Group 2: Safety Advantages - The unique "sandwich" structure of composite current collectors, featuring polymer layers such as PET and PP, provides excellent insulation and reduces the risk of thermal runaway by controlling short-circuit currents [2][3] - The reduced burrs produced during puncture tests indicate that composite current collectors can significantly enhance battery safety [3] Group 3: Cost and Equipment - The production cost of composite aluminum foil remains high due to reliance on imported Japanese equipment, with over 80% of total equipment costs attributed to vacuum coating machines [4] - Kewan Technology plans to invest 533 million yuan in equipment purchase and installation, with 450 million yuan allocated for 18 vacuum coating machines, each costing approximately 25 million yuan [4]
