The lithium-ion battery separator is a porous plastic film. It is a key component of the inner layer of the lithium battery. A separator with excellent performance plays an important role in improving the overall performance of the battery. For a long time, separator preparation technology has been mainly in the hands of foreign companies such as the United States and Japan. Since the separator is a high value-added material among lithium battery materials, accounting for about 30% of the cost of lithium batteries, these companies have monopolized the domestic separator market, keeping the domestic separator market price high, and constraining the development of my country's lithium-ion battery industry. the main bottleneck. In the "Twelfth Five-Year Plan for the Development of New Materials Industry" announced this year, the lithium-ion battery separator project was listed as a strategic emerging industry project supported by the state.

　　"Don't underestimate this film. It breaks the market price monopoly of foreign companies and kicks off the localization of lithium-ion battery separators." On April 11, Chairman of Shandong Zibo Zhenghua Additives Co., Ltd. Hou Yongzheng was holding the lithium-ion battery separator that had just come off the assembly line and told reporters happily.

　　"In the fierce market competition, the level of scientific and technological research and development holds the power of life and death of an enterprise. If an enterprise simply relies on old technology and old products, it will eventually come to an end." Hou Yongzheng believes this. Six years ago, when many people did not know much about lithium-ion battery separators, Hou Yongzheng, chairman of Zhenghua Additives Co., Ltd., keenly saw the huge business opportunities and development prospects contained in the lithium-ion battery separator project, and made a decisive decision In order to increase technological innovation and change the company's development plan of single industry structure.

　　The company organized scientific research and invested more than 100 million yuan. After six years of hard work, it finally successfully developed the lithium-ion battery separator preparation technology, breaking the blockade of this technology by foreign companies and successfully replacing imports. According to reports, the global demand for lithium-ion batteries and lithium-ion battery separators is increasing by more than 30% annually. With the gradual promotion of new energy vehicles, the demand for lithium battery materials will further increase in the future. At present, the company's 50 million square meters/year lithium-ion battery separator project has been included in the first batch of strategic emerging industry key projects in Shandong Province. It is expected that the production capacity will reach 20 million square meters by the end of April. After the project is completed and reaches full production, it will achieve sales revenue of 500 million yuan and profits and taxes of 200 million yuan.
