Once known as Shanghai Wisteria Packaging Materials Co., Ltd, as the company will focus on the transition to high value-added industrial films, in November 2011 the company formally changed its name, will become a listed company's new energy materials research and development, production and sales platform.

Zijiang new materials built 10000 square meters of 100,000 clean workshop, with casting, laminating, coating and slitting with the international leading level of imported equipment, mainly engaged in lithium-ion batteries with aluminum-plastic film, solar batteries with backsheet materials and new environmentally friendly energy-saving materials and other products, research, development, production and sales, specializing in lithium-ion batteries, solar batteries, construction and electrical appliances and other industries to provide products and Solutions.

As the main raw material for lithium-ion batteries, aluminum-plastic film, domestic lithium battery companies are mainly dependent on imports, and there are only a few suppliers in the world.

Lithium battery diaphragm exhaust mainly comes from lithium battery coating process, that is, lithium battery positive and negative electrode coating and diaphragm coating lithium battery positive and negative electrode coating is in the lithium battery positive and negative electrode coated with a layer of organic solvents (N-methyl pyrrolidone, ethanol) generated by the organic exhaust, lithium battery diaphragm coating is the surface of lithium battery diaphragm printing and packaging of the layer of organic solvents coated (acetone, ethanol).
