The rapid development of the electronic information industry has driven the continuous improvement of electrolytic copper foil production capacity

Copper foil can be divided into two types: electrolytic copper foil and rolled copper foil. Electrolytic copper foil refers to metal copper foil produced by electrolysis. Compared with rolled copper foil, electrolytic copper foil has the advantages of simple manufacturing process, low production cost, soft texture, and easy processing, and is a mainstream product in the copper foil market.

According to the “2022-2027 China Electrolytic Copper Foil Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, Electrolytic copper foil is a segmented product of copper foil, accounting for nearly 99.0% of the copper foil market. Driven by the rapid development of the electronic information industry, my country’s electrolytic copper foil production capacity continues to increase. According to statistics from the China Electronic Materials Industry Association, my country’s electrolytic copper foil production capacity will reach 721,000 tons in 2021, a year-on-year increase of 19.2%.

The production of electrolytic copper foil requires processes such as dissolving copper, purifying, preparing electrolyte, manufacturing copper foil, surface treatment, product slitting, and product testing. Electrolyte preparation is a key step in the production process of electrolytic copper foil, which will determine the quality and performance of electrolytic copper foil. The cleaned copper material needs to be dissolved into sulfuric acid, and then filtered, purified and other steps are performed to prepare a high-purity electrolyte. Although the electrolytic copper foil production process is not complicated, each link must be strictly monitored and controlled. my country’s electrolytic copper foil industry has low thresholds and lacks unified standards, resulting in uneven product quality. This is the main challenge facing the development of the industry.

                                                                                                                                                                                                          but due to the insufficient production of high-end electrolytic copper foil in our country, the production of high-end electrolytic copper foil has to rely on the import market, and the industry trade deficit is large. According to statistics from the General Administration of Customs of China, my country’s electronic copper foil imports will reach 131,000 tons in 2021, an increase of 21,000 tons compared with 2020 and a year-on-year increase of 19.1%. At present, the demand for high-end electrolytic copper foil in my country continues to grow. As production technology continues to make breakthroughs and innovations, it is expected that the localization rate of high-end electrolytic copper foil will increase in the future.

The development of the electrolytic copper foil industry is greatly affected by the demand in application fields. Electrolytic copper foil is an important raw material for the production of power batteries, automotive electronics, copper clad laminates (CCL), printed circuit boards (PCB) and other fields. From the perspective of the printed circuit board (PCB) field, as a provider of electrical connections for electronic components, my country’s printed circuit board (PCB) industry is developing well. According to statistics from the Electronic Copper Foil Materials Branch of the China Electrical Materials Association, my country’s printed circuit board (PCB) market size will reach US$44.20 billion in 2021, a year-on-year increase of 25.9%. The continued release of market demand provides broad development space for my country’s electrolytic copper foil industry.

Industry analysts said that driven by the rapid development of the printed circuit board industry, my country’s electrolytic copper foil market demand continues to rise, and industry development The outlook is bright. Affected by factors such as low industry thresholds, my country’s high-end electrolytic copper foil production is insufficient and needs to rely on the import market. With continuous breakthroughs in production technology, the market share of domestic high-end electrolytic copper foil will further increase, which will have a positive impact on the development of the industry.
