Tianhong New Material Co., Ltd. is a national high-tech enterprise specialized in the production, research and development, sales and service of lithium battery separator. The company has been actively practicing the concept of green development, promoting the realization of the "double carbon" goal, combining the digital, intelligent and networked development direction, taking root in the new energy vehicle industry chain, and focusing on the research and development and production of lithium battery separator.

Under an electron microscope, the film, which looks like a translucent plastic sheet, is evenly arranged with countless nanoscale micro-pores. Recently, in the laboratory of Tianhong New Material Co., LTD., Li Wangyang, deputy general manager of the company, told reporters that such a structure can make lithium ions in the case of isolating the positive and negative electrodes of the battery, still smooth passage. "As a key component of the technical barrier in lithium batteries, the diaphragm can separate the positive and negative electrodes, prevent battery short circuit, and ensure the free passage of lithium ions, which is as important to lithium batteries as the valve is to the heart." "Li said. Tianhong New Material is a national high-tech enterprise specializing in the research and development and production of lithium battery separator, and a national specialized new "little giant" enterprise. In recent years, the company, which started from food packaging film, has seized the "tuyere" of new energy vehicles, and has extensively carried out production-universation-research cooperation with the team of universities and institutes such as Sichuan University and Hefei University of Technology, and has deeply researched the research and development and production of new membrane Material such as lithium battery separator and degradable film, overcoming the core technology of lithium battery separator production - dry single pull technology, filling the domestic gap. This kind of lithium battery separator products broke the import dependence. The company's lithium battery separator and other products are widely used in new energy vehicles, energy storage, consumer electronics and other fields.

In 2022, Tianhong New Material was rated as a national intellectual property demonstration enterprise, a national postdoctoral workstation, a national intelligent manufacturing excellent scene, a national green factory, and a lithium battery separator were included in the Ministry of Industry and Information Technology's "lithium-ion battery Industry Specifications". Tianhong New Material has also won the titles of pilot unit of intellectual property application of industrial enterprises, China's top 100 Light Industry Science and Technology Enterprises, Anhui Province Technology Innovation Demonstration Enterprise, Anhui Province Smart Factory, Anhui Province new material Advantage Enterprise, Anhui Province "5G+ Industrial Internet" ten innovative applications, Anhui Province innovative Enterprise, Anhui Province first batch of new Material and so on. It is reported that at present, the company's existing 11 lithium battery diaphragm production lines have reached full production, the annual production capacity of 600 million square meters, is expected to reach 400 million yuan this year.

Since its inception, the company has always adhered to scientific and technological innovation. A total of 163 national invention patents have been applied for, of which 42 invention patents and 52 utility model patents have been authorized, and they have participated in the formulation of 2 national standards, 4 group standards, and 6 enterprise standards. Passed GB/T23001-2017 two integration management system certification, GB/T29490-2013 Intellectual property management system certification, IATF16949: 2016, IS09001 quality management system, IS014001 environmental management system certification and OHSAS Occupational health and safety management system, GB/T23331-2020/ISO50001:2018 standard and RB/T114-2014 energy management system, as well as the national industrial product production license.

With the rapid development of the new energy industry, the lithium battery separator industry has a very huge market prospects, Tianhong New Material will further expand the lithium battery separator production capacity and scale of investment, continue to aim at the industry chain leader, combined with industry demand, using their own advantages, brave and courageous forward, for the new energy industry to continue to empower.
