With the increase of domestic and foreign market demand, especially in the application and promotion of power electronics, new energy vehicles, smart grids and other fields, it is expected that the output of aluminum electrolytic capacitors in China will continue to maintain a growth trend. In the future, the continental aluminum electrolytic capacitor industry will develop towards high-end, diversified, customized, and green environmental protection.
1. Definitions and Classification
Aluminum electrolytic capacitor is a kind of capacitor that uses aluminum foil as the positive and negative plates, which refers to the capacitor formed by electrolysis by forming a very thin layer of alumina film on the surface of the aluminum foil as a dielectric. Aluminum electrolytic capacitors are characterized by high capacitance, high voltage, low ESR (equivalent series resistance), and long life. According to different drawing methods, aluminum electrolytic capacitors can be divided into lead type, solder type and bolt type; According to the different electrolyte materials, aluminum electrolytic capacitors can be divided into liquid aluminum capacitors and solid aluminum capacitors; According to different application fields, aluminum electrolytic capacitors can be divided into consumer, industrial, and military-grade aluminum electrolytic capacitors.

2. Relevant policies
In recent years, the mainland government has introduced many relevant policies to promote the development of the aluminum electrolytic capacitor industry, such as the Ministry of Industry and Information Technology and other five departments issued the "Action Plan for Accelerating the Green and Low-Carbon Innovation and Development of Power Equipment", which proposes to accelerate the breakthrough of a number of basic components, basic components, basic materials, basic software, basic technology, and industrial technology foundation of power equipment. Promote the integration and innovation of new materials and power equipment, and promote the collaborative innovation of the upstream and downstream of the industrial chain and the transformation and application of scientific and technological achievements. The policy emphasizes accelerating the breakthrough in the fields of basic components, basic components, and basic materials of power equipment, and aluminum electrolytic capacitors, as one of the indispensable basic components in power equipment, will benefit from this policy orientation and promote its innovation in materials, processes, and technologies. The performance and quality of an aluminum electrolytic capacitor is largely dependent on its base material (e.g., electrode foil, electrolyte, etc.) and manufacturing process. The support of the policy will promote the aluminum electrolytic capacitor industry to make breakthroughs in material research and development, process improvement, etc., so as to improve the overall performance and quality of products.
3. Industry barriers
1. Technical barriers
The production of aluminum electrolytic capacitors involves complex electrochemical techniques, delicate manufacturing processes, and strict quality control systems. These constitute a high technical barrier. First of all, enterprises need to master the core technologies such as accurate proportioning of electrolyte, efficient preparation of electrodes, and optimization of sealing technology. Secondly, in order to ensure the stability and reliability of products, enterprises also need to establish a sound quality inspection system to carry out comprehensive quality control of raw materials, semi-finished products and finished products. In addition, with the continuous progress of science and technology, new production technologies and processes are emerging, and enterprises need to continue to invest in research and development to maintain a leading position in technology, which also increases the difficulty and cost of technological innovation. Therefore, for new entrants who lack technology accumulation and R&D capabilities, the technical barrier is a gap that is difficult to cross.
2. Financial barriers
The aluminum electrolytic capacitor industry is a capital-intensive industry, which requires a large amount of capital investment from raw material procurement, production equipment purchase, production line construction to market promotion. Especially with the continuous improvement of the country's environmental protection requirements, enterprises need to invest more funds in the construction of environmental protection facilities and pollution control. This puts new entrants under tremendous financial pressure. At the same time, the competition in the aluminum electrolytic capacitor industry is becoming increasingly fierce, price wars are frequent, and the profitability of enterprises is declining. New entrants need to have sufficient capital reserves to deal with possible market risks and operating pressures.
3. Brand and market channel barriers
Brand and market channels are important assets for aluminum electrolytic capacitor companies, and they are also important barriers for new entrants. The leading enterprises in the industry have established a sound brand and market channel system, and have high brand awareness and market share. New entrants need to invest a lot of time and money in brand building and marketing to increase brand awareness and market share. At the same time, the customer relationship in the industry is also relatively stable, and customers have higher requirements for product quality and performance. New entrants need to spend more time and effort building and maintaining customer relationships to capture more orders and market share.
Fourth, the industrial chain
1. Analysis of the industry chain
The upstream products of raw materials for aluminum electrolytic capacitors mainly include high-purity aluminum, electrode foil, electrolyte, etc.; the middle of the industrial chain is the production and manufacturing of aluminum electrolytic capacitors; The downstream of the aluminum electrolytic capacitor industry chain is mainly used in power electronics, lighting, consumer electronics, communication equipment, automotive electronics, industrial control, new energy and other industries.
From the upstream point of view: the price fluctuations of raw materials such as high-purity aluminum, electrode foil, and electrolyte directly affect the production cost of aluminum electrolytic capacitors. When prices rise, if producers are unable to pass on costs downstream, their profit margins will be compressed; Conversely, falling prices may boost corporate profits. The quality of raw materials is directly related to the performance and reliability of aluminum electrolytic capacitors. High-quality raw materials can ensure the service life and stability of capacitors, while inferior raw materials may lead to substandard product performance, affecting corporate reputation and market competitiveness.
From the downstream point of view: the demand growth in the downstream market will stimulate the capacity expansion and technological innovation of the aluminum electrolytic capacitor industry. For example, with the rapid development of the new energy vehicle and renewable energy markets, the demand for high-performance and high-reliability aluminum electrolytic capacitors has increased, prompting manufacturers to increase R&D investment, improve product design, and improve the energy density, life and safety performance of capacitors.
