Sanmenxia Xing Bang special membrane technology development Co., Ltd.   

Sanmenxia Xing Bang special membrane technology development Co., Ltd. is currently the only high-tech company specializing in the development, production and sale of special membrane and lithium battery in Henan province. The registered capital is 16 million yuan, covers an area of 60 mu, and the production scale is 26 million square meters / year. The company has more than 30 people engaged in the project R & D team, and has independently developed the electrospinning film making method and membrane making device. After being investigated, the company has been at the leading level in the world, and has received more than 10 national patents. Currently, the energy storage type Li ion battery separator can be applied to lithium batteries and super capacitors of electric vehicles. The development of special ionic membrane products has diversified products, and can produce nanofiber membranes with a thickness of 10 to 100 microns and a porosity of 40% to 80% according to user needs. Through the national new energy battery research institute technology test and Hebei, Shanghai, Tianjin, Zhejiang, Shenzhen, Henan and other provinces and cities, many power lithium batteries and super capacitor manufacturers load test. The results show that the lithium battery produced by the electrospinning nanofiber membrane is twice as large as the lithium battery produced by the mechanical stretching method, and the battery life is prolonged by more than 30%. The test confirmed that the product is the ideal matching product for new energy vehicles and high-grade cars, with excellent quality and life expectancy of more than ten years. In August 2011, the product was certified by new products (Technology) experts of Henan provincial industrial and commercial bureau. Experts of the appraisal committee agreed that the product (Technology) has outstanding innovation from matrix selection, spinning and film-forming process and related equipment, and the main performance of the product has reached the advanced level of similar products at home and abroad. The company's own production of lithium iron phosphate batteries, with high capacity retention rate, can withstand continuous high current discharge, low self attenuation, cycle performance, long service life, environmental protection and pollution-free characteristics. It is the best choice for automobile starting power, pure electric vehicle, ship and electric bicycle. The cell adopts the nanofiber membrane produced by our company independently. It has the characteristics of high porosity, high permeability, good thermal stability and large volume of liquid absorption. Compared with the battery using ordinary separator, the charge and discharge performance of the battery is increased by about one time, and its service life is increased by more than 30%. All employees of Sanmenxia Xing Bang special Membrane Technology Exhibition Co., Ltd. are willing to cooperate sincerely with you and create brilliant future together.
