The equipment has good horizontal and vertical uniformity in rolling, and the appearance of the rolled products is high-quality. The equipment is supplied with pressure by the hydraulic system for roller rolling, suitable for situations where high requirements are placed on rolling force and consistency of rolling gaps.
The coating machine is a three roll transfer coating equipment that is convenient for surface coating processes on various substrates. Especially applied in the lithium-ion battery industry, while meeting the requirements of coating accuracy and consistency, it is designed with excellent drying effect.
Compared with traditional copper foil, PET substrate has good safety performance, light weight, and good ductility, which can help improve the energy density of batteries.
Composite aluminum foil is a new-type of battery current collector, which has thinner aluminum film, overall lighter weight, and higher safty during penetration expeirment compared to the conventional rolling aluminum foil.
