The high temperature resistant high porosity lithium ion battery separator is a new type of lithium ion battery separator with special non-woven fabric as the base material. The product has a three-dimensional network structure, which breaks through the traditional technical scheme of the material composition of the polyolefin microporous diaphragm and has high temperature resistance. High porosity, excellent electrolyte wetting, high liquid absorption and liquid retention, and excellent puncture resistance. The lithium ion power battery assembled with it has outstanding performance in terms of cycle life, safety and capacity. Mainly used in automotive power lithium-ion batteries and high-safety energy storage lithium-ion batteries.

Laizhou Lianyou Jinhao New Material Co., Ltd. was established in October 2007 with a registered capital of 10 million yuan and covers an area of nearly 30,000 square meters. It is a high-performance battery separator high-tech enterprise integrating R&D, production and operation.

The company's leading products are high temperature resistant high porosity lithium ion battery separator, nickel based power battery separator, nickel hydrogen battery separator, nickel cadmium battery separator, super capacitor diaphragm, zinc and silver battery separator, high performance battery separator for high speed train. In the domestic and foreign well-known battery manufacturers such as Keliyuan, Matsushita Energy, Zibo Guoli, etc., the products have not only met the high-performance requirements of new energy vehicles such as urban pure electric buses, urban light rail vehicles and hybrid electric vehicles. Moreover, it has been applied and promoted in the fields of high-safety energy storage, military, rail transit, environmental protection and energy conservation, and water treatment.

The company has established Shandong Fiber Functional Membrane Engineering Technology Research Center, Yantai Power Battery Diaphragm Engineering Technology Research Center, and Yantai City Enterprise Technology Center. It has initially built a domestic advanced high-performance battery separator R&D and testing platform
