1. Industry Overview: Basic Components and Strategic Value

  Aluminum electrolytic capacitors are indispensable basic components in electronic circuits, hailed as the 'vitamin of modern industry.' They account for approximately 34% of the global capacitor market. Currently, against the backdrop of China's accelerated advancement of 'new quality productive forces,' the strategic position of aluminum electrolytic capacitors in key areas such as new energy, new energy vehicles, and industrial power supplies has become increasingly prominent. In recent years, as Japanese manufacturers have gradually withdrawn from the mid-to-low-end market, domestic enterprises are accelerating their transformation towards high-end, green, and intelligent directions, deepening the process of domestic substitution.

  From a global perspective, the industry has roughly gone through three stages: the initial stage, the stage of development of solid aluminum electrolytic capacitors, and the stage of rapid industrial growth. Since the 21st century, countries and regions such as Japan, South Korea, and China have actively invested in technological research and development of solid aluminum electrolytic capacitors, focusing on the development of new electrolytes and exploration of solid-liquid hybrid technologies, which has rapidly improved product manufacturing levels and continuously expanded application ranges. Meanwhile, driven by rising overseas production costs, global manufacturing capacity has been comprehensively and rapidly transferred to mainland China, greatly promoting the growth of China's aluminum electrolytic capacitor industry.

  Although China's aluminum electrolytic capacitor industry started relatively late, it has developed rapidly, also going through roughly three development stages, and is currently in a period of high-speed growth. Domestic enterprises have achieved technological breakthroughs in some specific fields and successfully developed various high-end products. However, the overall industrial structure still mainly consists of mid-to-low-end products, with broad room for continuous improvement in both industrial scale and technological level.

Core of the Upstream Industrial Chain: Materials Determine Performance

  The upstream core raw materials of aluminum electrolytic capacitors mainly include aluminum foil, electrolyte, and electrolytic paper. Among these, aluminum foil is the key material that determines the overall performance, quality, and reliability of the capacitor. Its cost accounts for about 30%-60% in conventional products and can be as high as 50%-70% in large high-voltage products. The downstream application fields are extensive, covering consumer electronics, industrial lighting and power supplies, as well as strategically growing industries such as new energy and new energy vehicles.

2. Industry Development Trends: Advancement in High Performance and Greenness

  Looking ahead, the aluminum electrolytic capacitor industry will evolve towards higher performance, higher reliability, and greater environmental friendliness. Under the goals of 'dual carbon' and the green development orientation of the '14th Five-Year Plan,' low-energy consumption, lead-free, and recyclable capacitors have become research hotspots. At the same time, with the explosive demand from downstream sectors such as AI servers, 5G communications, and new energy vehicles, the market demand for high-end capacitors with characteristics such as high voltage, high frequency, and high temperature resistance continues to rise.

  Domestic enterprises should seize the development opportunities of 'new quality productive forces,' actively layout high-end product lines, break through key material and technological barriers, enhance their core competitiveness in the global industrial chain, and solidify the path of domestic substitution.
