复合铜箔行业：产业化拐点已至，对冲通胀与0到1成长共振：电力设备

Investment Rating - The industry rating is "Outperform the Market" [12] Core Insights - The composite copper foil industry is at a critical point of industrialization, with the product solutions becoming more mature. The industry is expected to penetrate mid-to-low-end demand scenarios in the context of high copper prices [3][4] - The composite copper foil offers advantages such as high cost-effectiveness, safety, and energy density, while facing challenges like high internal resistance and low cycle life. The technology consensus around the two-step method of magnetron sputtering and hydroelectric plating is forming [3] - The industry is projected to have a market space exceeding 100 billion, with significant players like Shengli and Baoming gradually advancing small-batch supply. The demand for lithium batteries is expected to reach approximately 3000 GWh by 2026, with a potential shipment volume of 6 billion square meters for composite copper foil [5] Summary by Sections Industry Dynamics - The national "14th Five-Year Plan" emphasizes accelerating the industrialization of composite conductive fluids, reflecting confidence in material performance and feasibility [3] - The rising costs in battery and vehicle manufacturing due to inflation necessitate cost reduction across all segments, which composite copper foil can address by partially replacing copper foil with plastic base films [4] Investment Recommendations - Future potential catalysts include significant business orders from key participants, financing and expansion by leading players, and large-scale deployment of composite copper foil products. It is recommended to focus on leading participants in composite conductive fluids (Shengli Precision, Baoming Technology) and hydroelectric plating equipment companies (Sanfu Xinke, Dongwei Technology) [5]
