Aluminum plastic film to open the process of localization

Aluminum plastic film to open the process of localization

In recent years, with the continuous growth of the market demand for soft-pack batteries, domestic aluminum-plastic film companies that have not yet achieved large-scale supply have ushered in new development opportunities. The industry's leading enterprises Zijiang Enterprises (600210.SH) and Buddha Plastic Technology (000973.SZ) gradually opened the process of domestic aluminum plastic film to replace imports.

Aluminum plastic film is divided into food grade aluminum plastic film and lithium battery aluminum plastic film. Food grade aluminum plastic film is a common packaging material, such as potato chips, capsule packaging and so on. The aluminum-plastic film process for polymer soft-packed lithium batteries is much more difficult. It was first developed jointly with Showa and SONY in 1999. At present, it is the only core material in the core that has not yet achieved large-scale localization, and the technical barriers are extremely high. Aluminum plastic film has extremely high requirements in related performance, far exceeding the diaphragm, positive electrode, negative electrode and electrolyte. The requirements mainly involve four aspects: barrier ability, puncture resistance, electrolyte stability, high temperature resistance and insulation. Any lack of any aspect may lead to a decrease in battery performance and direct scrap. It uses precision coating technology production, at present, the world's more advanced precision coating technology is mainly mastered by Japanese enterprises.

Key Technologies for Composite Hydrogen Storage Bottles

Key Technologies for Composite Hydrogen Storage Bottles

The composite material hydrogen storage cylinder includes an inner lining material, a transition layer, a fiber winding layer, an outer protective layer, and a buffer layer from inside to outside. The filling cycle of hydrogen storage cylinders may be relatively long, and hydrogen has strong permeability under high pressure. Therefore, the lining material of hydrogen storage tanks should have good barrier function to ensure that most of the gas can be stored in the container.
