On August 4th, Mengtai Hi-Tech (300876) issued an announcement that the company recently received an invention patent certificate issued by the State intellectual property Office. According to the announcement, the name of the patent for the invention is a wet paper-making process for manufacturing power lithium-ion battery separators.
It is worth noting that Mengtai Hi-Tech also announced on July 15 that it had recently received a patent certificate issued by the State intellectual property Office on the method of manufacturing lithium battery separators with PE-PP orange flap-shaped composite ultra-fine denier fiber.
If we continuously obtain the invention patent for the manufacture of lithium diaphragm, will the production road of Mengtai high-tech diaphragm be opened?
Mengtai Hi-Tech said that the above invention patent is independently developed by the company and has not yet been applied in mass production products, and the acquisition of the patent will not have a significant impact on the company's production and operation, but it will help to further improve the company's intellectual property protection system, give full play to the advantages of independent intellectual property rights, promote technological innovation, and enhance the company's core competitiveness.
Battery Network noted that Mengtai Hi-Tech also said on the investor interactive platform a few days ago that the lithium-ion battery separator and its manufacturing method are still in the stage of research and development and have not yet been mass-produced.
According to the Guohai Securities Research report, with the general trend of global electrification, global electric vehicle sales are expected to exceed 16 million in 2025. Driven by the steady growth of consumer batteries and the rapid growth of energy storage and power batteries, the global demand for lithium batteries is expected to reach 1400G in 2025. CAGR will reach 38% in 2021-2025, corresponding to 22.2 billion square meters of diaphragm demand, and 35% CAGR in 2021-2025.
Under the huge market demand potential, the domestic (C3H6) n fiber leader Mengtai Hi-Tech has been involved in the field of lithium new energy.
